Carbon Quantum dots
Carbon Quantum Dots (CQDs) are a class of nanomaterials composed of carbon-based nanoparticles with sizes typically below 10 nanometers. These particles possess unique optical, electrical, and chemical properties, which distinguish them from bulk carbon materials like graphite and graphene. CQDs are often characterized by their bright fluorescence, excellent biocompatibility, and ease of surface modification, making them highly versatile for a wide range of applications.
Applications
Biomedical Applications:
Bioimaging and Biosensing: CQDs are used as fluorescent probes for bioimaging due to their strong fluorescence and low cytotoxicity. They can be used to label cells, tissues, and biomolecules for in vivo and in vitro imaging. Furthermore, CQDs are employed in biosensors for detecting biomolecules, such as glucose, proteins, and nucleic acids, with high sensitivity and selectivity.
Drug Delivery: CQDs can be functionalized to carry drugs and other therapeutic agents. Their small size and surface-modification capabilities enable them to effectively deliver drugs to targeted cells or tissues, improving the efficiency of treatments.
Cancer Therapy: CQDs can be used in photothermal therapy, where their ability to absorb light and convert it into heat is used to target and destroy cancer cells. Additionally, their high surface area allows them to be functionalized with specific molecules that target cancer cells for enhanced therapy.
Photodynamic Therapy: CQDs can act as photosensitizers in photodynamic therapy (PDT) for cancer treatment. When exposed to light, CQDs generate reactive oxygen species (ROS) that can damage cancerous tissues, offering a non-invasive treatment option.
Environmental Sensing and Detection:
Heavy Metal Ion Detection: CQDs can be functionalized to selectively detect heavy metals like mercury, lead, and cadmium in water and soil. Their fluorescence properties change in the presence of these ions, making them useful for environmental monitoring and pollution control.
pH and Temperature Sensors: Due to their size-tunable fluorescence properties, CQDs can be used as pH and temperature sensors. Changes in environmental conditions affect the fluorescence emission of CQDs, making them effective for real-time monitoring in various environments.
