The Superhero of Molecule Detection: Gold Nanoflowers and Nanoislands

November 30, 2024

Ever tried to find a tiny needle in a massive haystack? That's similar to detecting specific molecules like Rafiki 6G (R6G) in a crowded environment. Surface-enhanced Raman scattering (SERS) is like a super-powered microscope that can spot these rare molecules. But making a surface that consistently

Gold Complexes that Change Color When Crushed: A Cool Science Experiment

November 30, 2024

Scientists have made six new kinds of gold complexes that contain something called fluorene. They used fancy tools like NMR, mass spectrometry, and X-ray diffraction to figure out what these complexes look like. Before being crushed, these complexes glow in different colors like blue-green, yellow-g
