New Findings on Skin Cancer from Linkoping University Summarized (Photodynamic effects of zinc oxide nanowires in skin cancer and fibroblast)

July 15, 2014

By a News Reporter-Staff News Editor at Cancer Weekly -- New research on Oncology is the subject of a report. According to news originating from Norrkoping, Sweden, by NewsRx correspondents, research stated, "Cytotoxic effects of zinc oxide (ZnO) nanomaterials, individual and conjugated with a photosensitizer (protoporphyrin IX), were studied in the presence and absence of ultraviolet light exposure (240 nm of light wavelength for a very short time exposure) in cell cultures of human normal and cancerous skin models."

Our news journalists obtained a quote from the research from Linkoping University, "Zinc Oxide nanowires (ZnO NWs) were grown on the capillary tip and conjugated with protoporphyrin IX (PpIX). This coated tip was used as tool/pointer for intracellular drug delivery protocol in suggested normal as well as carcinogenic cellular models."

According to the news editors, the research concluded: "After true delivery of optimal drug, the labelled biological model was irradiated with UV-A, which led to a loss of mitochondrial membrane potential, as tested by neutral red assay (NRA)."
