Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

Advanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Microbial drug resistance and the roles of the new antibiotics.

Cleveland Clinic Journal of Medicine, 2001
Physicians should be cautious in prescribing broad-spectrum antibiotics, particularly vancomycin and the fluoroquinolones, because widespread use of these drugs is promoting antibiotic resistance. Resistance is now found in many organisms, including staphylococci, enterococci, streptococci, pneumococci, and Pseudomonas aeruginosa.

Fabrication of a Lipopolysaccharide‐Targeting Peptide‐Based Colloid for Alleviating Carbapenem‐Resistant Enterobacteriaceae‐Induced Cutaneous Infection

Advanced Healthcare Materials, EarlyView.
In this study, a novel cationic peptide, IW is designed and synthesized, with a tandem‐repeat sequence demonstrating potent activities against a broad spectrum of clinically relevant Carbapenem‐resistant Enterobacteriaceae in both the planktonic and biofilm states. IW is then formulated with P407 to form IW‐P407 colloids.

Effectiveness of Antibiotics: Anti-Bacterial Activity or Microbial Drug Resistance?

Bangladesh Journal of Microbiology, 2020
Antibiotics, both broad- and narrow spectrum, are widely used for treatment of specific infection by a consortium of microorganisms or by a single pathogen, respectively. Oral or intravenous, or even topical administration of different categories of antibiotics in various forms is a common practice round the globe.
