Nanotechnology

Ever wondered how tiny tests can deliver big answers in minutes? Join us for a hands-on workshop that cracks open the science behind biosensors—tiny, clever devices that behave like biological detectives. It’s the same science behind blood-glucose tests, and rapid COVID kits—and in this workshop, you’ll see exactly how it works.

The real showstopper? Optical biosensors powered by gold nanoparticles. When a target such as a bacterium, toxin, or antibiotic binds to the biosensor, the gold nanoparticles shift from red to blue right before your eyes. No bulky instruments. No complicated electronics. Just add a drop of sample and watch the science happen. Simple, affordable, and fast—these sensors are transforming testing in homes, clinics, and the field.

Professor Juewen Liu

Professor Liu’s research group applies the fundamental principles of chemistry, physics, and biology to produce nanoscale materials, devices, and systems to understand basic sciences, advance technology, and impact medicine.
