Abstract
This paper reports an Ag–Bi–S-based nanotheranostic platform with an ingeniously designed heterostructure, an appropriate size, and good imaging and therapy performances. By comparing the fluorescence property and Bi element content, the optimal heterostructure was demonstrated to be Ag2S/Bi2S3 core/shell. The hydrophilic Ag2S/Bi2S3-PEG nanocrystals with hydrodynamic diameter of 37.56 nm exhibited near-infrared-II fluorescence, good CT imaging contrast, and a high photothermal conversion efficiency (38.4%), and have shown significant potential in the precision diagnosis and treatment of tumors.
期刊介绍：
Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C.Journal of Materials Chemistry B is a Transformative Journal and Plan S compliant. Example topic areas within the scope of Journal of Materials Chemistry B are listed below. This list is neither exhaustive nor exclusive：
Antifouling coatings
