Application

Cadmium Telluride Quantum Dots (CdTe QDs) are available in solid form. They are coated with carboxyl groups which makes them water soluble to make aqueous solutions. These carboxyl functionalized hydrophilic quantum dots can be further conjugated for use as labels. CdTe QDs can be used for optical and display applications; solar cells and biomedical applications.

This study was undertaken to evaluate the antioxidant potential of an aqueous extract from Merremia emarginata leaves because this plant has a very high flavonoid and phenol content. The in vitro antioxidant activity was measured by diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic
