Optical spectra of silver nanoparticles in aqueous solution (a), silver nanoparticles in chloroform solution (b) and silver nanoparticles encapsulated liquid crystalline dendrimer (c) 4. Conclusions Optical spectra of fourth generation liquid crystalline poly(propylene-imine) PPI dendrimer with antimicrobial silver nanoparticles in chloroform solution were investigated. Shift of plasmon resonance peak towards to IR region about 20 nm in the PPI-Ag system was observed in comparison with pure silver nanoparticles in chloroform and silver nanoparticles in distilled water.
