Nano compound on their size and composition we can observe peculiar properties, such as quantum confinement in semiconductor nanocrystals, surface Plasmon resonance in some metal NPs and super para magnetism in magnetic materials. Noble metal NPs, in particular gold and silver NPs, are among the most extensively studied Nanomaterials and have led to the development of numerous techniques and methods for molecular diagnostics, imaging, drug delivery and the rapeutics. Most of their unique physicochemical properties at the nanoscale, such as Localized Surface Plasmon Resonance (LSPR), have been explored for the development of new biosensors. This review will focus on these unique physicochemical properties of noble metal NPs that have thus far been explored for the development of new highly sensitive and specific bio sensing techniques, favouring those that have already been successfully tested with biological samples.

Silver Nano Particle Ink

Silver Nano Particle Ink

Silver Nano Particle Ink: Printed electronics will bring to the consumer level great breakthroughs and unique products in the near future, shifting the usual paradigm of electronic devices and circuit boards from hard boxes and rigid sheets into flexible thin layers and bringing disposable electronics, smart tags, and so on. The most promising tool to achieve the target depends upon the availability of nanotechnology-based functional inks. A certain delay in the innovation-transfer process to the market is now being observed. Nevertheless, the most widely diffused product, settled technology, and the highest sales volumes are related to the silver nanoparticles-based ink market, representing the best example of commercial nanotechnology today.

Nano Dimensions provides conductive inks specifically tailored for use in antennas, including radio-frequency identification (RFID) technology for a variety of devices including smart cards, various ID products, arrays and more. The Nanoshel family of silver nanoparticles inks, deposited by contactless, digital, inkjet printing, delivers outstanding results.

Nano Dimension has also developed a suite of dielectric inks to meet the advanced needs of the electronics community. The insulating properties of these materials are just as important and advanced as the conductive properties of the conductive inks. For electronic circuits to function properly, properties relating to interference, adhesion, thermal dissipation and flammability have to be engineered into the ink. Our one-part nano-epoxy insulating dielectric material provides solutions suited for both rigid and flexible circuits.

Silver Nano Particle Ink

Probably the first nanotechnology ever discovered and applied was that of black ink based on carbon black and bone black, containing fullerenes and a wide variety of aromatic small molecules. Today, printing technology has expanded its horizon toward the realization of electron devices on any substrate, according to two main approaches: 1) analog printing, involving the use of linear/rotary machines that are able to realize multiple copies of the same pattern at a rather high speed (serigraphy, gravure, offset, flexography), involving generally micro structured inks; and 2) digital printing, where raster machines realize at rather slow speed a single copy of a pattern that could be changed simply working at the software level (inkjet printing, 3-D printing), involving nanostructured inks.

In order to exploit the potential of metal NPs fully and to provide effective strategies to tune electronic and optical properties of materials, the control of size and morphology of nanostructures are of fundamental and technological interest.60 Noble metal NPs (Ag, Au, Pt) are extremely interesting because of their unique properties, and among them Ag possess the highest electrical and thermal conductivity, along with other properties, which promote its extensive use in a wide range of applications. Nowadays, Ag NPs are largely used to produce conductive tracks with inkjet printing, thanks to the high conductivity and thermal stability of such materials.

Conductive inks normally are aqueous or organic solvent dispersions of silver NPs that are stabilized by surfactants and polymers that undergo printing, a drying step, and at the end a sintering process that is commonly achieved by heating the printed substrates to a temperature usually higher than 200°C. Alternatively, more unconventional techniques, such as microwave, laser radiation, flash sintering, plasma and electrical- or chemical-induced sintering, can be pursued.

Sintering at 200°C is much below the melting point of silver (960°C), and it can be attributed to the enhanced surface diffusion of atoms and to surface premelting; therefore, even in the sintering process, the dimension and shape of Ag NPs are one of the first properties to be investigated.

Ag NPs used for inks generally have spherical shape with diameters ranging from 5 to approximately 100 nm with narrow dimensional distribution. Several works are presented in the literature using such NPs. Fuller et al described an inkjet ink based on colloidal silver NPs of spherical shape with a diameter of approximately 5–7 nm dispersed 10 wt% in α-terpineol, which was sintered at 300°C on a hot plate, giving conductive lines of 80 µm and presenting a resistivity of 3 µΩ/cm.

Ag-based inks for inkjet-printing flexible electronics

Concentrated silver NPs are well-recognized materials with potential applications in the field of printing technology. These are used for the preparation of metallic structures on various substrates, because of their high electrical conductivity and resistance to oxidation. Such inks should meet some important requirements: for instance, they should not dry out and clog when in the print-head, they should have good adhesion to the substrate with limited coffee-ring effect and reduced particle aggregation, and they should be characterized by suitable viscosity and surface tension, as they determine drop size, drop-placement accuracy, satellite formation, and wetting of the substrate. These requirements are very well met by Ag NP-based inks.

Alloy Nanoparticles

 Alloy Nanoparticles

Alloy Nanoparticles are cornerstones of nano science and nanotechnology. Nano structure science and technology is a broad and interdisciplinary area of research and development activity that has been growing explosively worldwide in the past few years. It has the potential for revolutionizing the ways in which materials and products are created and the range and nature of functionalities that can be accessed. It is already having a significant commercial impact, which will assuredly increase in the future. Some nano materials occur naturally, but of particular interest are engineered nano materials (EN), which are designed for, and already being used in many commercial products and processes. They can be found in such things as sunscreens, cosmetics, sporting goods, stain-resistant clothing, tires, electronics, as well as many other everyday items, and are used in medicine for purposes of diagnosis, imaging and drug delivery.

The two main reasons why Alloy Nanoparticles at the nano scale can have different properties are increased relative surface area and new quantum effects. Nano materials have a much greater surface area to volume ratio than their conventional forms, which can lead to greater chemical reactivity and affect their strength. Also at the nano scale, quantum effects can become much more important in determining the materials properties and characteristics, leading to novel optical, electrical and magnetic behaviors. Nano materials are already in commercial use, with some having been available for several years or decades. The range of commercial products available today is very broad, including stain-resistant and wrinkle-free textiles, cosmetics, sun screens, electronics, paints and varnishes. Nano coatings and nano composites are finding uses in diverse consumer products, such as windows, sports equipment, bicycles and automobiles.

Metal Oxide Nanoparticles

 Metal Oxide Nanoparticles

PROPERTIES OF Metal Oxide Nanoparticles: The current knowledge on oxide materials allows to affirm that most of their physical-chemical properties display an acute size dependence. Physical-chemical properties of special relevance in Chemistry are mostly related to the industrial use of oxides as sensors, ceramics, absorbents and/or catalysts. A bunch of novel application within these fields rely on the size-dependence of the optical, (electronic and/or ionic)transport, mechanical and, obviously, surface/chemical (redox, acid/base) properties Metal Oxide Nanoparticles. We should stress that size effects in oxide chemistry have frequently two interrelated faces, structural/electronic quantum-size and size-defect or non-stoichiometry effects. Hence, here we will describe the influence of these two phenomena in the main physic-chemical properties of oxides.

THE WORLD OF Metal Oxide Nanoparticles

Metal Oxide Nanoparticles play a very important role in many areas of chemistry, physics and materials science. The metal elements are able to form a large diversity of oxide compounds. These can adopt a vast number of structural geometries with an electronic structure that can exhibit metallic, semiconductor or insulator character. In technological applications, Metal Oxide Nanoparticles are used in the fabrication of microelectronic circuits, sensors, piezoelectric devices, fuel cells, coatings for the passivation of surfaces against corrosion, and as catalysts. In the emerging field of nanotechnology, a goal is to make nanostructures or nano arrays with special properties with respect to those of bulk or single particle species.

Metal Oxide Nanoparticles can exhibit unique physical and chemical properties due to their limited size and a high density of corner or edge surface sites. Particle size is expected to influence three important groups of basic properties in any material. The first one comprises the structural characteristics, namely the lattice symmetry and cell parameters. Bulk oxides are usually robust and stable systems with well-defined crystallographic structures. However, the growing importance of surface free energy and stress with decreasing particle size must be considered: changes in thermodynamic stability associate with size can induce modification of cell parameters and/or structural transformations and in extreme cases the Metal Oxide Nanoparticles can disappear due to interactions with its surrounding environment and a high surface free energy. In order to display mechanical or structural stability, metal oxide nanoparticles must have a low surface free energy.

Metal Oxide Nanoparticles As the particle size decreases, the increasing number of surface and interface atoms generates stress/strain and concomitant structural perturbations. Beyond this “intrinsic” strain, there may be also “extrinsic” strain associated with a particular synthesis method which may be partially relieved by annealing or calcinations. Also, non-stoichiometry is a common phenomenon. On the other hand, interactions with the substrate on which the Metal Oxide Nanoparticles are supported can complicate the situation and induce structural perturbations or phases not seen for the bulk state of the oxides.
