[The study of antimicrobial properties of silver nanoparticles in the form of a colloidal solution in the matrix of finely dispersed silica].

In the experimental study obtained with chemical method colloid solution of nanoparticles (NPs) of silver (Ag) and a composite on his base in the matrix of finely dispersed silica with particle size of 8-12 nm and NPs concentration in basic solution of 0,0016% (0,016 mg/cm3) were established to exhibit high antimicrobial activity against the test organisms: E. coli, P. aeruginosa, S.

[Study of the mechanisms of interaction between intestinal bacteriophages and polyaluminum coagulants].

The authors have investigated the adsorption-elution of intestinal bacteriophages T2 and MS2 as a model of enteric viruses, by using the coagulants aluminum oxychloride (AOX78) and aluminum sulfate (AS). The investigation has ascertained the effective removal of the phages from water with AOX78 (98.7-100%) and the low efficiency of elution of coliphages from the particles of AOX hydrolysis products (0.
