Quantum dot manufacturing relies on a process called high temperature dual injection which has been scaled by multiple companies for commercial applications that require large quantities (hundreds of kilograms to tons) of quantum dots. This reproducible production method can be applied to a wide range of quantum dot sizes and compositions.
Carbon quantum dots have been extensively investigated especially due to their strong and tunable fluorescence emission properties, [7] which enable their applications in biomedicine, optronics, catalysis, and sensing. [8]
One of the most important properties of core–shell semiconducting nanocrystals (CSSNCs) is that their cores, which are quantum dots, fluoresce, which is important in their biomedical and optical applications. [53] The shells are highly modular, and thus the bulk properties, such as solubility and activity of the CSSNCs can be changed.
In order to use quantum dots in many biology related applications, the quantum dots must be soluble in aqueous environments. For quantum dots to be solubilized in water, the amphiphilic ligands must be on the surface of quantum dots. DNA can be used as a solubilization ligand due to its amphiphilic nature. [1]
The dots can be random in size, can be made of bio-inert material, and they demonstrate the nanoscale property that color is size-dependent. As a result, sizes are selected so that the frequency of light used to make a group of quantum dots fluoresce is an even multiple of the frequency required to make another group incandesce.
Silicon quantum dots have been used in prototype applications owing to their biocompatibility and the ubiquitous nature of silicon, compared to other types of quantum dots. In addition to these fundamental properties, the unique optical properties of silicon quantum dots (i.e., long-lived excited states, large Stokes shift and tunable ...
She has also explored the use of quantum dots as optical waveguides, and the applications of metal halide perovskites in integrated photonics. [3] She has developed efficient solar cells based on quantum dots [ 4 ] and optical tweezers for biological sampling, and contributed to optogenetics , the light-based control of biological cells, using ...
[2] [3] Some of the contributions he has made to science and engineering has been (a) the development of quantum dots for biomedical applications, [4] [5] (b) the size and shape dependent cellular interactions of nanoparticles in vitro and in vivo, (c) the identification of the protein corona on nanoparticle and its effect on cancer targeting ...
