Copper Nanoparticles

Applications

Catalysis

Chemical Synthesis: Copper nanoparticles are widely used as catalysts in various chemical reactions, including oxidation, hydrogenation, and coupling reactions. Their high surface area and reactivity make them more efficient than bulk copper in promoting these reactions. For example, they are used in the selective hydrogenation of organic compounds in the production of pharmaceuticals and fine chemicals.

Electronics and Sensors

Conductive Materials: Due to their high electrical conductivity, are used in the fabrication of conductive inks, electrodes, and circuits for printed electronics. They are also applied in the production of flexible and wearable electronic devices, where traditional conductors like copper wires may not be practical.

Sensors: Copper nanoparticles are employed in sensor technology for detecting gases, chemicals, and biological molecules. Their high surface reactivity and the ability to undergo rapid changes in conductivity or optical properties in response to stimuli make them ideal for use in chemical sensors and biosensors.

Biomedical Applications

Antimicrobial Activity: Copper nanoparticles are known for their antimicrobial properties and are used in wound dressings, medical devices, and antibiotic coatings to prevent infections. The nanoparticles can kill bacteria, fungi, and viruses, making them useful in healthcare settings.

Drug Delivery: Copper nanoparticles are studied for their ability to act as drug delivery systems, particularly for cancer therapy. They can be functionalized with various drugs or therapeutic agents and targeted to specific sites in the body, increasing the efficacy and minimizing side effects of treatments.

Cancer Therapy: Copper nanoparticles can also be used in photothermal therapy (PTT) for cancer treatment. When exposed to near-infrared light, these nanoparticles absorb the energy and convert it into heat, which can be used to kill cancer cells in a localized area.
