From ANI London, Aug 11: Scientists from University of Virginia have developed new light-emitting biomaterial that could improve tumour imaging. The new material is an oxygen nanosensor that couples a light-emitting dye with a biopolymer and simplifies the imaging of oxygen-deficient regions of tumours. Such tumours make cancer aggressive and difficult to treat. The new material is based on poly(lactic acid), a biorenewable, biodegradable polymer that is safe for the body and the environment, and is easy and inexpensive to fabricate in many forms, including films, fibers and nanoparticles. It is being useful for medical research as well as environmental research, sustainable design and green products. The research team along with cancer researchers at Duke University Medical Centre synthesized the new material by combining a... [read full story]
