Micro Powders

Micro Powders

Micro Powders play a very important role in many areas of chemistry, physics, and materials science. The metal elements can form a large diversity of oxide compounds by employing various synthesis techniques. They exhibit metallic, semiconductor, or insulator character due to the electronic structure difference. The variety of attributes of oxides enable the wide applications in the fabrication of microelectronic circuits, sensors, piezoelectric devices, fuel cells, coatings against corrosion, and as catalysts. For example, almost all catalysts involve an oxide as active phase, promoter(or support) which allows the active components to disperse on.

Micro Powder In the chemical and petrochemical industries, products worth billions of dollars are generated every year through processes that use oxide and metal/oxide catalysts. For the control of environmental pollution, catalysts or sorbents that contain oxides are employed to remove the CO, NOx, and SOx species formed during the combustion of fossil-derived fuels. Furthermore, the most active areas of the semiconductor industry involve the use of oxides. Thus, most of the chips used in computers contain an oxide component. Till now, there are still many potential applications of materials under continuous investigation and new synthesis methods being developed. To exploit new applications metal oxide materials is one of the mean purposes of inorganic chemist. Micro Powders are usually robust and stable systems with well-defined crystallographic structures.

Micro Powder and metal borides, because of their extreme hardness and abrasiveness, are used in the manufacture of specialty saw blades and abrasive wheels. Both have very high melting points: 3350°C and 3000°C, respectively. Due to its high hardness, Micro Powders powder is used as an abrasive in polishing and lapping applications, and also as a loose abrasive in cutting applications such as water jet cutting. It can also be used for dressing diamond tools.

Metal Nanoparticles

 Metal Nanoparticles

Metal-nanoparticles In the last decade the use of Metal Nanoparticles has been having a great impact in bio sensing. In particular, the unique properties of noble metal Nanoparticles have allowed for the development of new bio sensing platforms with enhanced capabilities in the specific detection of bioanalytes. Noble metal Nanoparticles show unique physicochemical properties (such as ease of functionalization via simple chemistry and high surface-to-volume ratios) that allied with their unique spectral and optical properties have prompted the development of a plethora of bio sensing platforms. Additionally, they also provide an additional or enhanced layer of application for commonly used techniques, such as fluorescence, infrared and Raman spectroscopy. Herein we review the use of noble metal nano particles for bio sensing strategies—from synthesis and functionalization to integration in molecular diagnostics platforms, with special focus on those that have made their way into the diagnostics laboratory.

Metal-nanoparticles are, in general, one of the most common nanotechnology-based approaches for enveloping biosensors, due to their simplicity, physiochemical malleability and high surface areas. They can measure between 1 to 100 nm in diameter, have different shapes and can be composed of one or more inorganic compounds, such as noble metals, heavy metals, iron, etc. The majority of them exhibit size-related properties that differ significantly from those observed in micro particles or bulk materials.

Metal-nanoparticles on their size and composition we can observe peculiar properties, such as quantum confinement in semiconductor nanocrystals, surface Plasmon resonance in some Metal Nanoparticles 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 Nanoparticles 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. While some recent reports have addressed specific bio-application for noble Metal Nanoparticles,
