Background
While silver nanoparticles (AgNPs) are increasingly attractive as an antibacterial agent in many applications, the effect of AgNPs on bacterial protein profiles, especially AgNPs stabilized by polymeric molecules, is not well understood.
Objectives
To investigate the changes in bacterial protein patterns by AgNPs capped with poly (4-styrenesulfonic acid-co-maleic acid) (AgNPs-PSSMA) polymer toward
Methods
The growth of bacteria after incubated with AgNPs-PSSMA for different time intervals was determined by optical density at 600 nm. Their protein patterns were observed using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), and the proteomic analysis of extracted proteins was determined by liquid chromatography-tandem mass spectrometry (LC–MS/MS).
Results
AgNPs-PSSMA was able to inhibit the growth of both
Conclusions
The antibacterial effect of AgNPs-PSSMA may arise by changing the bacterial proteins and thus interfering with the normal cell function.
