Contact lenses for diagnostic and therapeutic use

Human bodily fluids and secretions contain molecules known as biomarkers that contain a wealth of information about the body’s health and the presence of disease. Among secretions such as tears, sweat and saliva, tears are considered the best source of biomarkers, with concentrations similar to those found in blood. Tears are also sterile, readily available […]

Detecting bacteria with fluorescent nanosensors

Researchers from Bochum, Göttingen, Duisburg, and Cologne have developed a new method for detecting bacteria and infections. They use fluorescent nanosensors to track down pathogens faster and more easily than with established methods. A team headed by Professor Sebastian Kruß, formerly at the University of Göttingen, now at Ruhr-Universität Bochum (RUB), describes the results in […]

New Nanoparticle Antitumor Vaccines Control Melanoma Growth in Preclinical Models

At the Wistar Institute, researchers merged synthetic DNA technology with their expertise in protein engineering to successfully create nanoparticle antitumor vaccines that stimulated strong CD8 T cell immunity and regulated melanoma growth in preclinical models……. https://www.azonano.com/news.aspx?newsID=37525&utm_source=azonetwork_newsletter&utm_medium=email&utm_campaign=nanoparticles_and_colloids_newsletter_6_october_2020

Ultra-Sensitive Graphene-Based Sensors for Next-Generation Surgical Robotics

Sensors have played a crucial role in medicine and life sciences as a medium to monitor vital organs and diagnose patients. However, the current conventional sensors developed by various sensing methods, such as lateral flow immunoassay (Viro Research, 2019), fluorescent microarray (Jaksik, Iwanaszko, Rzeszowska-Wolny, & Kimmel, 2015), electrochemical methods (Song, Xu, Kuroki, Liao, & Tsunoda, 2018), […]

Giant nanomachine aids the immune system

Cells that are infected by a virus or carry a carcinogenic mutation, for example, produce proteins foreign to the body. Antigenic peptides resulting from the degradation of these exogenous proteins inside the cell are loaded by the peptide-loading complex onto so-called major histocompatibility complex molecules (MHC for short) and presented on the cell surface. There, […]

Magnetic gold nanohybrid will help fight cancer

A team of NUST MISIS scientists, together with colleagues from Russia and Germany, have presented a detailed study of magnetite-gold nanohybrids. In the future, such nanoparticles can help in theranostics—the diagnostics and subsequent therapy of oncological diseases. The results of the work have been published in the Journal of Materials Chemistry B.
