Abstract

Highlights

Bioimaging is a very useful modern method for disease diagnosis and investigation of biological processes [1, 2]
The valence band maximum of CIS quantum dots (QDs) is composed of hybrid orbitals of S and Cu [3]; a decrease in the proportion of copper in the QDs leads to a decrease in the copper contribution to the formation of the valence band maximum
In order to make the QDs synthesized in an organic medium compatible with biological fluids and tissues, it is necessary to convert their hydrophobic ligand shell into a hydrophilic one

Summary

Introduction

Bioimaging is a very useful modern method for disease diagnosis and investigation of biological processes [1, 2]. The main goal that has to be achieved for an effective bioimaging is the use of a highly luminescent phosphor with long-term stability of properties under different conditions, as well as with the minimum possible toxicity. The most promising luminophores for this application are quantum dots (QDs). The use of QDs for bioimaging has significantly improved its capacity.
