Description 1171-1175
Quantum Dots (QDs) are ultra-fine nanometer-sized semiconductor particles with a core-shell structurepossess both
electrical and optical properties. Their unique ability to emit pure, monochromatic light on being exposed to light makes
them extremely versatile in their applications. The color of the light emitted directly depends on their size and shape.
Smaller QDs emit shorter wavelengths, closer to the violet end of the visible light spectrum (~380-450 nm), while larger
QDs emit longer wavelengths i.e in reddish spectrum (~620-750 nm).
Owing to their “tunability”, QDs can be exploited in a wide range of fluorescent, photonic, and electrochemical
applications. QDs represent elements mainly from Group II-VI (e.g., CdSe) or Group III-V (e.g., InP) with the resultant
optical and electronic properties of the quantum dots being somewhere between bulk semiconductor material and individual
atoms or molecules. Besides applications in energy and photonics, they are under extensive investigation and development
for use in disease diagnosis and therapy, specifically in the area of controlled drug delivery, biosensing and imaging. This
review surveys the progress of research explores their properties, synthesis, applications, delivery systems in biology, and
their toxicity.
