Polydopamine Nanoparticles, 100 mg dry powder
Polydopamine nanoparticles are synthetic nanoparticles formed from the polymerization of dopamine, a neurotransmitter found in the human brain.
Features:
Versatile Surface Chemistry: Polydopamine nanoparticles possess a high affinity for binding to various substrates, including metals, polymers, ceramics, and biological materials. This property allows for easy functionalization of the nanoparticle surface with different molecules, such as drugs, proteins, antibodies, or imaging agents, enabling their use in targeted drug delivery, imaging, and sensing applications.
Adhesive Properties: Polydopamine nanoparticles exhibit strong adhesive properties, similar to those found in natural adhesives, such as mussels. This makes them useful for surface coating and bonding applications, including coating of medical devices, improving the biocompatibility of implants, and enhancing the adhesion of materials in various industries.
Biocompatibility: Polydopamine nanoparticles are biocompatible, they have low toxicity and are well tolerated by living organisms. This property makes them promising candidates for various biomedical applications, including drug delivery, tissue engineering, and bioimaging.
Photothermal Conversion: Polydopamine nanoparticles can convert light energy into heat due to their strong light-absorbing properties. This feature has been exploited for applications in photothermal therapy, where the nanoparticles are used to selectively generate heat in targeted tissues or tumors, leading to localized cell destruction.
Stability and Durability: Polydopamine nanoparticles exhibit excellent stability and durability, allowing them to retain their properties under various environmental conditions, including changes in pH, temperature, and salt concentration. This stability enhances their potential for long-term applications and storage.
