Functionalised iron nanoparticle–penicillin G conjugates: a novel strategy to combat the rapid emergence of β-lactamase resistance among infectious micro-organism

Figures & data

Figure 1 UV–visible spectrum of iron solution (…▪…), native iron nanoparticles (-•-) and functionalised iron nanoparticles (-▴-).

Figure 2 (a) AFM image of native iron nanoparticles and (b) its particle size distribution. For size distribution analysis, the diameter of approximate 100 particles were analysed.
