@ Atul, actually silver cation is not a particle so you cannot compare. Obviously, you may compare between silver mega-particle with nano- silver particles. Due to nano-size and excellent penetration capacity, I think, silver nanoparticles may be more toxic than silver mega-particles at similar concentration.
J. C. Tarafdar Sir, obviously, silver cation is not a nanoparticle but silver cation is considered as Lewis acid which react with Lewis bases such phosphorus and Sulphur containing biomolecules. Similarly, when bacterial cell exposed to silver nanoparticles, silver ion release from it and exerts its effect on cell. Some times or most of the time silver nanoparticles act as silver bullet that directly fracture the cell. So, in this respect I asked the question.
Thank you sir for your insightful answer.
Definitely, it will be helpful in getting in depth knowledge.
