Characterization of the stability (non-aggregation) of three sized antibiotic nanocarriers (AgMUNH-Oflx NPs) in the modified LB medium using UV–vis absorption spectroscopy. The UV–vis absorption spectra of 6 nM, 0.8 nM, and 7 pM AgMUNH-Oflx NPs for the Ag NPs with diameters of (A) 2.4 ± 0.7, (B) 13.0 ± 3.1, and (C) 92.6 ± 4.4 nm in the modified LB medium at (a) 0 and (b) 24 h remain essentially unchanged over time, which indicates that the nanocarriers are stable (non-aggregated) in this medium over 24 h.
