Synthesis,.PhysicoChemical.Properties,.and.Biologic.Activity.of.Nanosized. Silver.Particles

During.the.last.decade.in.different.fields.of.science,.medicine,.and.engineering,.nanosized.metallic. particles.have.been.used.with.great.success..The.importance.of.nanosized.particles.was.stressed. in.1959.by.Richard.Freiman,.winner.of. the.Nobel.Prize. in.physics,. in.his. lecture.at. the.California.Institute.of.Technology:.“There.is.Plenty.of.Room.at.the.Bottom.in.Miniaturization,”.during. which.he.told.of.the.immense.possibilities.of.materials.and.devices.of.atomic.and.molecular.size.. He. pointed. out. that. in. small. assemblies. of. atoms,. quantum. effect. must. be. taken. into. account,. and.that.physical.laws.do.not.exclude.the.possibility.of.developing.such.systems..Beginning.from. the.1990s,.the.amount.of.publications.on.nanotechnology.and.its.use.in.different.fields.increased. sharply.[1-5]..Buchachenko.[2].noted.the.increased.importance.of.chemistry.for.the.development. of.nanotechnology..Even.before.the.beginning.of.the.“Nanoboom,”.different.small-sized.systems. were.investigated.by.scientists,.such.as.microorganisms,.aerosols,.catalysts,.carbon.black,.zeolytes,. ultradisperse.powders,.thin.films,.and.many.others..Many.archeologic.discoveries.showed.the.use.of. colloid.systems.in.the.ancient.world.(for.example,.the.use.of.“Chinese.ink”.in.ancient.Egypt)..Thus,. the.modern.concept.of.nanotechnology.includes.also.many.“old”.fields.of.science.[4,5].
