Lipid nanoparticles carry gene-editing cancer drugs past tumor defenses

As they grow, solid tumors surround themselves with a thick, hard-to-penetrate wall of molecular defenses. Getting drugs past that barricade is notoriously difficult. Now, scientists at UT Southwestern have developed nanoparticles that can break down the physical barriers around tumors to reach cancer cells. Once inside, the nanoparticles release their payload: a gene editing [...]

Graphene Nanosensor Detects Biomarkers Through Tears

In an article recently published in the journal Talanta, researchers demonstrated a new approach to enable the specific detection of biomarkers in human tear by employing an aptamer-based graphene affinity nanosensor. The ability to detect and measure the biomarkers in undiluted physiological fluids allows the application of nanosensors in measuring the biological fluid samples whose [...]

Towards Carbon Clean Manufacturing with Eco-Friendly Nano-Lubricants

Grinding is an essential manufacturing process, yet the heat due to friction associated with the process causes damage to the part being processed. Lubrication is used to reduce friction; however, traditional petroleum-based lubricants can harm the environment and are hazardous to humans. A paper published in the Journal of Cleaner Production addresses the issues associated with [...]
