Because of already predominant and prevalent all over the world and highest grade utilization of different smallest to largest size silver nanoparticle (AgNps) consumer products and raised concern of scientific voice in particular for the aquatic environment, analytical and various scientific techniques for the characterization of such consumer products are of need and bound necessary. However because smallest to largest size silver nanoparticle (AgNps) consumer products are of different compositions like chemical stabilizer and deagreegator and polydispersities, analysis and characterization especially of the various size distribution curve is really challenging.

In this work an asymmetric flow field fractionation (A4F) multi detector system (UV/vis), thin layer liquid and surface chromatography, dynamic light scattering, inductive couple plasma mass spectrometry- ICPMS), Zeta potential, Image J estimation and spectroscopy in combination with a method to distinguish and quantify the size of different particles and it’s segregation and dissolved Ag fractions (ICPMS after ultracentrifugation), for the characterization of AgNps consumer products with different degrees of polydispersities is presented.

In this composition, an endeavor is made to illustrate the amalgamation and characterization of silver nano particles with a wide run of sizes (from 2.75 nm up to 1908.2 nm in sweep) by lessening silver nitrate powder with polyvinyl pyrollidone in watery arrangements within the nearness of a sodium borohydride stabilizer. The coming about particles were found circular totals with a unpleasant surface and poly dispersity file underneath 18.26%.(>0.783PDI) The molecule optical, cummulant, diluents and electrical conductivity properties were inspected by energetic light diffusing and zeta potential but morphology was assessed after examination by transmission electron microscopy & image-j. Silver nanoparticles were specifically coated with polyvinyl pyrollidone with a sodium borohydride stabilizer. Optical properties on a single-particle level were examined by implies of auto relationship work estimations. The successful poly dissimilarity list of the charged silver nanoparticles was moo sufficient to make a colloidal gem at moo ionic quality. Colloidal shape is found more harmful than suspended particles in 1.5 molar sodium chloride arrangements; this appears increment of silver nano particles estimate due to agglomeration, will diminish the harmfulness but increment teratogenicity.
