TL;DR: The reduction of [Ag(NH(3))(2)](+) by maltose produced silver particles with a narrow size distribution with an average size of 25 nm, which showed high antimicrobial and bactericidal activity against Gram-positive and Gram-negative bacteria, including highly multiresistant strains such as methicillin-resistant Staphylococcus aureus.

TL;DR: In this article, a simple one-step method of silver nanoparticle (NPs) preparation with controlled size is introduced, where silver NPs were prepared by reduction of [Ag(NH3)2]-complex cation by d-maltose in the presence of low concentrations (1 × 10−10 mol/L to 1 × 10 −7 mol /L) of high-molecular-weight poly(acrylic acid) (PAA), this modification of the reduction reaction results in managing the prepared silver nanoparticles' size in the range from 28 nm
