Title: Innovations of Xiaomin Niu in Quantum Dots Technology
Introduction
Xiaomin Niu is an accomplished inventor based in Philadelphia, PA, known for his significant contributions to the field of quantum dots technology. He has been instrumental in developing innovative solutions for in vivo near-infrared imaging applications. His work has led to the creation of two notable patents that showcase his expertise and creativity in this cutting-edge area of research.
Latest Patents
Xiaomin Niu's latest patents focus on the synthesis of tin sulfide quantum dots (SnS QDs) for in vivo near-infrared imaging. The patents describe an aqueous approach to synthesize capped SnS QDs, which involves attaching one or more extending molecules to the capping molecule via peptide bond formation at elevated temperatures. The capped SnS QDs may have a capping molecule to Sn:S molar ratio ranging from 16:3:1 to 16:12:1. A suspension of SnS QDs was heat-treated at 200°C for 0.5 to 4 hours, resulting in QDs that exhibited an NIR emission peak at 820-835 nm with an excitation wavelength of 690 nm. The synthesized SnS QDs demonstrated a high positive zeta potential of approximately 30 mV, indicating potential cytotoxicity. However, by neutralizing the SnS QDs, the cytotoxicity was reduced to an acceptable level. Notably, the heat-treatment step can be bypassed by adding a glycerol solution containing Sn anions and capping molecules to a glycerol solution of Sn ions.
