Review on UV – Visible Spectroscopy and HPLC
Abstract: Like Fourier-transform infrared spectroscopy, UV-visible spectroscopy is used to determine the purity of pharmaceutical compounds. Many substances have chromospheres, which absorb certain wavelengths of ultraviolet or visible light. Using the Beer–Lambert equation, the absorption of spectra obtained from these samples at given wavelengths can be directly related to the sample concentration. Normally, UV and UV-visible spectra are recorded at high and low pH, and the results of both are compared …

Development and Performance Evaluation of a Polyethersulfone–Graphene Oxide Ultrafiltration Membrane for Simultaneous Drug Delivery and Virus Removal: An Experimental Investigation
Abstract: The development of multifunctional ultrafiltration membranes for simultaneous controlled drug delivery and viral removal has gained considerable attention in biomedical engineering, pharmaceutical sciences, and water purification. Polyethersulfone (PES) membranes offer excellent thermal, chemical, and mechanical stability; however, their hydrophobicity can limit permeability, antifouling performance, and biocompatibility. This study proposes the fabrication of PES–graphene oxide (GO) ultrafiltration membranes using the phase inversion technique, with systematic variation of GO concentration to optimize …

The Ames Test in Twenty-first Century
Abstract: Since the 19th century, industrial development has increased exposure to mutagens and possible carcinogens. In order to avoid these health risks, several techniques have been developed to recognize genotoxins. In the 1970s, Dr. Bruce Ames and colleagues, studying the histidine operon of Salmonella typhimurium, observed that histidine (−) auxotroph mutants were reverted to histidine (+) upon exposure to a mutagen. The researchers further observed that known carcinogens were mutagenic to …
