COOH Functionalized MWCNTs (>95%, OD: 20-30 nm)

COOH Functionalized MWCNTs

COOH functionalized MWCNTs have a wide range of applications due to the unique combination of enhanced dispersion, increased reactivity, and biocompatibility provided by the carboxyl groups on their surface.

Biomedical Applications

Drug Delivery Systems

NA are widely used as carriers for drug delivery. The carboxyl groups on their surface can be used to attach drugs, therapeutic agents, or biomolecules. This functionalization enhances the solubility and bioavailability of poorly soluble drugs. Furthermore, can be targeted to specific cells or tissues, improving the efficacy of the treatment and reducing side effects.

For example:

Cancer therapy: NA can be loaded with anticancer drugs (e.g., doxorubicin) and delivered directly to tumor sites, increasing the drug’s effectiveness while minimizing damage to healthy cells.

Biosensors and Diagnostics

The surface chemistry of makes them ideal for use in biosensors. The carboxyl groups provide reactive sites for attaching biological recognition elements (e.g., antibodies, enzymes, DNA strands), enabling highly sensitive detection of biomolecules. These sensors can be used for medical diagnostics (e.g., detecting glucose levels, DNA markers, or protein biomarkers) or environmental monitoring.

Tissue Engineering

NA can be incorporated into scaffolds for tissue engineering. NA their biocompatibility and ability to interact with cells enhance the growth and proliferation of cells, making them suitable for the development of artificial tissues or organs, such as bone or cartilage.
