Tunable, bacterio-instructive scaffolds made from functional graphenic materials

Abstract

Functional graphenic material (FGM) scaffolds instruct bacterial attachment through electrostatic interactions with the bacterial cell wall.

Calcium phosphate graphene and Ti3C2Tx MXene scaffolds with osteogenic and antibacterial properties

“…A possible cause for this phenomenon may be the surface charge of MXene versus CaPG, as MXene has a more negative surface potential than CaPG (Figure S5). 42,43 The presence of both the antibacterial as well as antifouling properties observed with differing MXene weight percentages allow for tunability in the desired application.…”

Ionic liquids revolutionizing biomedicine: recent advances and emerging opportunities

“…ILs offer a promising strategy to address this issue. 79 Due to the negative electrostatic charge present on bacterial cell surfaces, 80,81 the cations of ILs can easily affect the bacterial surface. 82,83 Meanwhile, the combination of different cations and anions produces a wide range of ILs with tunable structures, enabling the customization of their properties against bacteria, such as Gram-positive Staphylococcus aureus (S. aureus), Gram-negative Pseudomonas aeruginosa (P. aeruginosa), and Escherichia coli (E. coli).…”

Quaternized Silk Fibroin Nanocarriers Loaded with Chlorin e6 for Photodynamic Elimination of Drug-Resistant Bacteria and Biofilms

“…The combination of nanocarriers and PSs could enhance the water solubility and diffusion distance of PSs, allowing them to effectively aggregate at the infection site. This enhanced the efficacy of photodynamic activity. , In addition, positively charged bacteria have received immense attention because they can selectively target negatively charged bacterial membranes through strong electrostatic adsorption. − Therefore, the fabrication of a cationic nanocarrier-loaded PSs with small size and low toxicity is theoretically feasible.…”
