Applications

Biomedical Applications

Drug Delivery:
OH-MWCNTs are used as carriers for drug delivery systems. The hydroxyl groups on the surface of MWCNTs can form covalent bonds with various therapeutic agents, including drugs, proteins, and genes. These functionalized nanotubes can be designed for targeted drug delivery, which helps increase the effectiveness of treatment and minimize side effects. The hydroxyl groups also enhance the solubility of the MWCNTs, making them more compatible with biological fluids for in vivo applications.

Biosensors:
OH-functionalized MWCNTs are employed in the development of highly sensitive biosensors. The hydroxyl groups enable the functionalization of MWCNTs with biological recognition elements, such as antibodies or enzymes. This enhances the ability of the biosensor to detect specific biomolecules, such as cancer markers or pathogens, with high precision. These sensors can be used for early disease detection, environmental monitoring, and food safety.

Tissue Engineering:
In tissue engineering, OH-MWCNTs are used to enhance the mechanical properties of scaffolds for cell growth and tissue regeneration. The functional groups on the surface of MWCNTs promote cell adhesion and proliferation, which is essential for regenerating tissues like bone, cartilage, or nerve cells. The integration of OH-MWCNTs into scaffolds leads to improved scaffold performance, supporting more efficient tissue growth.

Energy Storage and Conversion

Supercapacitors:
OH-MWCNTs are used in the development of supercapacitors—devices that store electrical energy. The functionalization of MWCNTs with hydroxyl groups enhances their dispersion and improves their interaction with electrolytes. This results in higher energy and power densities, as well as better cycling stability. OH-MWCNTs are incorporated into the electrodes of supercapacitors to increase their charge/discharge rates and efficiency.

Lithium-Ion and Sodium-Ion Batteries:
OH-functionalized MWCNTs are used to enhance the performance of lithium-ion batteries and sodium-ion batteries. In these applications, OH-MWCNTs are integrated into the anode or cathode materials, improving their conductivity, capacity, and cycling stability. The hydroxyl groups help improve the interfacial bonding between the MWCNTs and active materials in the battery, enhancing the battery’s overall efficiency and lifespan.
