Abstract

Correction for ‘Synthesis and antimicrobial photodynamic effect of methylene blue conjugated carbon nanotubes on E. coli and S. aureus’ by Paramanantham Parasuraman et al., Photochem. Photobiol. Sci., 2019, DOI: 10.1039/c8pp00369f.

Biodegradable MoOx@MB incorporated hydrogel as light-activated dressing for rapid and safe bacteria eradication and wound healing

“…The loading capacity of MB by MoO x NPs was measured by the reported method with slight modications. 42 2 mg of MoO x @MB NPs and 2 mL of absolute ethanol were mixed and then vortexed for 5 min to accelerate the release of MB. Then, to collect the released MB, the mixture was centrifuged at 12 000 rpm for 20 min.…”

Photosensitizer Anchored Nanoparticles: A Potential Material for Photodynamic Therapy

“…The carbon-based NPs are extensively used in tumor therapy due to their improved optical features, less toxicity, antimicrobial activity, and better compatibility. The recent usage of carbon-based materials such as Fullerenes, [115] Carbon nanotubes, [116] and Graphene [117] based NPs are used for PDT. It is ideal for drug delivery due to the π-π stacking.…”

“…Functionalized single-walled carbon nanotubes (SWCNTs) produced photodynamic inactivation on the cell membrane and enhanced antibacterial activity. This led to improved free radical production for PS anionic dye like methylene blue [116] and rose Bengal. [127] While cationic dye such as malachite green functionalized on the multi-walled carbon nanotubes (MWCNTs) produced better phototoxicity against different pathogens and eliminated the biofilms formed by the drugresistant micro-organism.…”

A hemostatic keratin/alginate hydrogel scaffold with methylene blue mediated antimicrobial photodynamic therapy

“…17 With the use of methylene blue as a photosensitizer, light of appropriate wavelength and molecular oxygen causes aPDT to generate reactive oxygen species that destroy microbial cells. 18 In the present study, we combined the characteristics of keratin and alginate, and enhanced the mechanical strength and wound dressing properties of keratin by adding alginate to composite scaffolds. The composite scaffolds were physically crosslinked by Ca 2+ to reduce the side effects of chemical crosslinking degradation products on the human body and speed up the hemostatic cascade via Ca 2+ release.…”
