Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
Quantum Dots Chemical Sensing for various ions is in progress and is of main concern currently. Ion sensing can be carried out using QDs via analyte-induced changes in the photoluminescence of QDs

For ion detection, Quantum Dots Chemical Sensing is the most usual process observed after interaction between quantum dot and organic analytes, usually involving photo-induced electron transfer (PET) and Förster resonance energy transfer (FRET)

Quantum Dots Chemical Sensing that have a receptor part based on a biochemical principle are usually called biosensors. The selectivity and sensitivity provided by Nature have been utilized in such sensors, frequently by immobilizing the biologically active compounds, such as enzymes and immunoglobulins, within a receptor part of the sensor. An effective way of obtaining the biological selectivity is a combination of cell cultures, tissue slices, organs and sometimes of whole living organisms with the transducer.

Quantum Dots Chemical Sensing can be based on various optical principles (absorbance, reflectance, luminescence, fluorescence), covering different regions of the spectra (UV, Visible, IR, NIR) and allowing the measurement not only of the intensity of light, but also of other related properties, such as lifetime, refractive index, scattering, diffraction and polarization. As an example, a luminescent sensor can be constructed by associating a sensing element, which emits light when in contact with a specific analyte, with a photodiode, which converts the energy of the incident light into a measurable signal.

Quantum Dots Chemical Sensing have numerous advantages over conventional electricity-based sensors, such as selectivity, immunity to electromagnetic interference, and safety while working with flammable and explosive compounds. They are also sensitive, inexpensive, non-destructive, and have many capabilities. Optrodes do not require a reference cell, as is the case in potentiometry. Furthermore, they can easily be miniaturized and allow multiple analyses with a single control instrument at a central site.
