Research into the potential anticancer activity of gallium was stimulated by the discovery that 67 Ga, when injected into rodents bearing implanted tumors, localized in high concentration within these tumors. This discovery led the development of the 67 Ga scan as a method for detecting tumors in patients and prompted further evaluation of the …

Unidimensional photonic crystal-based biosensors have gained much attention in the area of blood glucose measurement.

Pure gallium (Ga) is not widely studied for electrochemical CO 2 reduction (EC CO 2 R) due to its low melting point near room temperature. However, in this study, metallic Ga was selected and subjected to EC CO 2 R under varying conditions of applied potentials, electrolytes, concentrations, and photoirradiation. The results showed that …
