How to prevent nanosilver and carbon nanotubes from becoming toxic to organisms, especially from harming the body when they enter the blood, lungs or other sensitive parts?
Sarada K Gopinathan
Surface Coating: Coating nanosilver particles with biocompatible materials can reduce their toxicity. Size Control: Smaller particles are more likely to be toxic, so controlling particle size can help mitigate risks. Stabilization: Using stabilizing agents to prevent aggregation can reduce the likelihood of toxic effects. Surface Functionalization: Modifying the surface of CNTs with functional groups can mitigate adverse biological responses. Purity and Consistency: Ensuring the purity and consistency of raw materials used in CNT synthesis can prevent toxicity due to contaminants and surface defects. Aspect Ratio Control: Restricting the use of CNTs with high aspect ratios, as long CNTs can have asbestos-like pathogenicity, which can be alleviated by chemical modification or shortening.
For Nanosilver:
For Carbon Nanotubes:
Also, check for cytotoxicity of the synthesized material via computation and invitro, vivo studies for further clarifications.
