Abstract
AbstractQuantum dots are the most innovative molecules created in the modern era. These molecules are of nano-size ranged from 1-10 nm with unique photoluminescence characteristics. The unique properties of luminescence madethem an excellent candidate for cellular labelling and detection markers. The fabrication by conjugating with a library of biomolecules opened the gates for various innovative bioimaging and diagnostic protocols and drugdelivery systems. Having these versatile properties, QDs are originating as next-generation bio-nanotechnological tools for mankind to answer many biomedical issues in the fields of diagnosis and treatment. In this book chapter, a comprehensive discussion was made on the QDs, and their critical physico-optical characteristics, and their application in bioimaging, diagnosis, and drug targeting.KeywordsPhotoluminescenceDrug deliveryBioconjugationBiomarkersBioimagingDetection
