TI  - Synthesis, characterization and antibacterial assessment of 
      SiO(2)-hydroxypropylmethyl cellulose hybrid materials with embedded silver 
      nanoparticles.
PG  - 747-752
AB  - Antibacterial SiO(2) hybrid materials based on tetraethyl orthosilicate (TEOS), 
      hydroxypropylmethylcellulose (HPMC) and silver were prepared by the sol-gel 
      method. The content of cellulose derivate was 5 wt% and the silver concentration 
      varied from 0.5 wt% to 2.5 wt%. The amorphous nature, morphology and 
      antibacterial behaviour were studied. Fourier transform infrared (FTIR) spectra 
      of the hybrids showed characteristic peaks for SiO(2) network. Scanning electron 
      microscope (SEM) analysis confirmed the formation of spherically shaped silver 
      nanoparticles with a size of 30 nm on the matrix surfaces. Bacillus subtilis and 
      Escherichia coli K12 were used as model microorganisms. The hybrid materials 
      demonstrated bacteriostatic and bactericidal effect on the tested bacteria. 
      Highest sensitivity to the obtained hybrids was observed in B. subtilis with 
      significant lag-phase delay and biggest inhibition zone sizes.
