Metallic nano particles as emulsion stabilisers

Recently, the research focus is shifting towards replacing classic surfactants with colloidal particles in stabilizing emulsions. This review gives an overview of utility of metallic nanoparticles as emulsion stabilizers. The emphasis is on the use of metallic nanoparticle stabilized Pickering emulsions as carriers for antibiotics. It’s an established fact that metallic nanoparticles possess antimicrobial properties themselves and can be a good choice for formulating drug delivery systems. Additionally, they have a capability to evade drug resistance mechanisms in bacteria. Metals like gold, silver, copper, iron, manganese etc are used extensively. So, combining plant based antimicrobials and a metallic nanoparticle into one drug delivery system, with an add-on of the recommended antibiotic seems a promising possibility.
