Scientists discover ‘tug of war’ in gold nanoparticles, opening path for advanced biosensors

Indian scientists have discovered how everyday molecules like amino acids and salts influence the behaviour of gold nanoparticles, a finding that could pave the way for more reliable biosensors, improved diagnostic tools and advanced drug delivery systems. Gold nanoparticles are widely used in optical technologies because of their unique interaction with light. Their colour and optical properties change depending on whether they remain isolated or form clusters. While this makes them useful in ...

Tiny gold nanoparticles show promise in early detection of Parkinson’s Disease

Scientists at the Institute of Nano Science and Technology (INST), Mohali, have developed a nanotechnology-based tool that could enable early detection of Parkinson’s Disease (PD), one of the fastest-growing neurological disorders worldwide. The research team explored how proteins behave differently in the brain during disease and focused on α-synuclein, a protein closely linked to Parkinson’s. This protein, which is harmless in its normal form, tends to clump into toxic aggregates that da...
