While many people love colorful photos of landscapes, flowers or rainbows, some biomedical researchers treasure vivid images on a much smaller scale – as tiny as one-thousandth the width of a human hair. To study the micro-world and help advance medical knowledge and treatments, these scientists use fluorescent nano-sized particles. Quantum dots are one type of nanoparticle, more commonly known for their use in TV screens. They’re super tiny crystals that can transport electrons. When UV light hits these semiconducting particles, they can emit light of various colors. That fluorescence allows scientists to use them to study hidden or otherwise…
