A black phosphorus based synergistic antibacterial platform against drug resistant bacteria

Abstract

Black phosphorus nanosheets were decorated with Ag nanoparticles through an in situ growth strategy, exhibiting synergistic antibacterial activity against drug-resistant bacteria.

A nontoxic biocompatible nanocomposite comprising black phosphorus with Au–γ-Fe2O3 nanoparticles

“…Au-g-Fe 2 O 3 -black phosphorus (AIB) nanocomposite 2.3.1 Synthesis of BP NSs. BP NSs were prepared from bulk BP crystals by adopting a method previously reported by Ouyang et al 18 with slight modication. Initially, 2.0 g of NaOH was added into 60 mL of N-methyl-2-pyrrolidone (NMP) and sonicated in water bath for 5 min.…”

Black Phosphorus Nanosheets Counteract Bacteria without Causing Antibiotic Resistance

“…This offers the possibility of using exfoliated BPNs as antibacterial agents. Several groups have reported that black phosphorus is successful in killing bacteria, however, the antibacterial mechanism is not clear. Therefore, we systematically examined the antibacterial actions of BPNs by incubating two model species, Escherichia coli ( E. coli , a Gram‐negative bacterium) and Staphylococcus aureus ( S. aureus , a Gram‐positive bacterium), in the presence of different concentrations of BPNs (0.01–5 mg mL −1 ) of different thickness (bulk, 1000 and 15 000 rpm).…”

Nanomaterials as Delivery Vehicles and Components of New Strategies to Combat Bacterial Infections: Advantages and Limitations

“…BP has recently emerged as a new potential antibacterial agent. The layer-dependent wide range bandgap (0.3–2.0 eV) of BP compared to the zero bandgap of graphene makes it an ideal candidate for near-infrared (NIR) light irradiated antibacterial activity [101]. More information related to NIR and its use in clinical application is given in Section 3.7.…”

“…It also has natural biodegradable properties in vivo unlike the much-researched graphene which requires functionalization for biodegradable properties. Furthermore, BP acts both as a supportive substrate and a green reductant for Ag [101] and Au [102] NPs, which are known to be excellent nano-sized antibacterial materials.…”
