Time-dependent Phosphorescence Color of Carbon Dots in Binary Salt Matrices through Activations by Structural Confinement and Defects for Dynamic Information Encryption.

Angewandte Chemie, 2023
The emergence of time-dependent phosphorescence color (TDPC) materials has taken information encryption to high-security levels. However, due to the only path of exciton transfer, it is almost impossible to obtain TDPC for chromophores with a single ...

Universal Phosphorescence Immunoassay

Analytical Biochemistry, 1994
The aim of this study is to develop a universal phosphorescence immunoassay method using monoclonal antibodies to Pd-coproporphyrin (Pd-CP) and conjugates of various proteins with Pd-CP. Pd-CP and monoclonal antibodies obtained allow a convenient method for the determination of various antigens to be developed.
