In this article we review the key technologies for GaN based materials and devices. Developments in the methods for thin film deposition by metalorganic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE) and resulting film properties are highlighted. Breakthroughs in materials growth has enabled extremely high efficiency blue and green GaN LEDs to be achieved for the first time. GaN LEDs complete the primary color spectrum and have enabled bright and reliable full-color solid state displays to be realized. Recently, room temperature operation of pulsed current injection blue-violet lasers emitting at 417 nm has further increased possible applications for GaN based optoelectronic devices.

We herein report a facile, green, cost-effective, plant-mediated synthesis of gold nanoparticles (AuNPs) for the first time using Combretum erythrophyllum (CE) plant leaves. The synthesis was conducted at room temperature using CE leaf extract serving as a reducing and capping agent. The as-synthesized AuNPs were found to be crystalline, well dispersed, and spherical in shape with an average diameter of 13.20 nm and an excellent stability of over 60 days. The AuNPs showed broad-spectrum antibacterial activities against both pathogenic Gram-positive (Staphylococcus epidermidis (ATCC14990), Staphylococcus aureus (ATCC 25923), Mycobacterium smegmatis (MC 215)) and Gram-negative bacteria (Proteus mirabilis (ATCC 7002), Escherichia coli (ATCC 25922), Klebsiella pneumoniae (ATCC 13822), Klebsiella oxytoca (ATCC 8724)), with a minimum inhibition concentration of 62.5 µg/mL. In addition, the as-synthesized AuNPs were highly stable with exceptional cell viability towards normal cells (BHK- 21) and cancerous cancer cell lines (cervical and lung cancer).
