Detection of protein by optical sensors based on II-VI quantum dots.

Abstract

roteins are essential biomolecules within the body, playing critical roles in various biological processes. Due to the importance of proteins in cellular functions, it is necessary to monitor their concentrations and the processes in which they participate. Quantum dots (QDs) are nanoscale colloidal particles with advanced optical and electronic properties compared to larger particles. In contrast to traditional organic fluorescent reagents, QDs exhibit several unique characteristics, including a narrow emission spectrum, high resistance to photobleaching, high luminous efficiency, and a large Stokes shift. These properties make QDs highly promising for applications in biosensing. The use of fluorescent QDs in biosensing, especially for protein detection, holds significant potential. The aim of the study. This study aims to summarize existing literature on protein detection using optical sensors based on II-VI quantum dots, to inform new scientific and practical advancements.
