What are the Applications of Size Tunable Fluorescence?
Size tunable fluorescence has numerous applications across various fields:
1. Biomedical Imaging: Quantum dots are used as fluorescent probes for imaging due to their high brightness and stability compared to traditional dyes. Their size-dependent emission allows for multiplexing, where different sized quantum dots can be used to label different biological targets simultaneously.
2. Displays and Lighting: Nanomaterials with size tunable fluorescence are used in LEDs and display technologies. For example, quantum dot LEDs (QLEDs) provide high color purity and efficiency.
3. Sensing and Detection: These materials are also employed in biosensors and chemical sensors. Their fluorescence properties can change in response to the presence of specific molecules, making them excellent for detecting various substances.
