Light-activated molecular machines display broad spectrum antibacterial action
<p>TEM images of <em>E. coli</em> treated with 1% DMSO or 0.5x MIC of different visible light-activated molecular machines. Light-activated molecular machines (MM) are synthetic molecular structures that, following light activation, undergo successive unidirectional rotation that results in a drilling-like rapid motion that can thrust the motor through biological membranes. Transmission electron microscopy (TEM) images revealed that treatment of <em>E. coli</em> with 0.5x MIC of different MM (DL-654, DL-877, DL-878) followed by activation with 42.6 J cm<sup>-2</sup> of 405 nm light resulted in substantial changes in cell morphology including the detachment of the inner membrane from the cell wall, damage to peptidoglycan, distortion of the cell surface, and formation of outer membrane vesicles, denoting membrane and periplasmic stress, that were not evident in 1% DMSO-treated and irradiated cells. </p>

Data from: Antibacterial activity of graphene oxide nanosheet against multi drug resistant superbugs isolated from infected patients
Graphene oxide (GO) is a derivative of graphene nanosheet which is the most promising material of the decade in biomedical research. In particular, it has been known as an antimicrobial nanomaterial with good biocompatibility. In this study, we have synthesized and characterize GO and checked its antimicrobial property against different Gram-negative and Gram-positive multi drug resistant (MDR) hospital superbugs grown in solid agar-based nutrient plates with and without human serum through the utilization of agar well diffusion method, live/dead fluorescent staining and genotoxicity analysis. The main focus of the antimicrobial activity analysis is to distinguish the killing performance of GO in artificial and blood containing media because after injection into the bloodstream the activity of GO may be modified by adsorption of blood proteins or other biomolecules. No significant changes in antibacterial activity were found in these two different conditions. We also compare the bactericidal capability of GO with some commonly administrated antibiotics and in all cases the degree of inhibition is found to be higher. The data presented here are novel and show that GO is an effective bactericidal agents against different superbugs and can be used as a future antibacterial agent.
