Recent Nanotechnologies to Overcome the Bacterial Biofilm Matrix Barriers

Small, Journal Year: 2022, Volume and Issue: 19(6)

Published: Dec. 5, 2022

Abstract Bacterial biofilm‐related infectious diseases severely influence human health. Under typical situations, pathogens can colonize inert or biological surfaces and form biofilms. Biofilms are functional aggregates that coat bacteria with extracellular polymeric substances (EPS). The main reason for the failure of biofilm infection treatment is low permeability enrichment therapeutic agents within biofilm, which results from particular features matrix barriers such as negatively charged components highly viscous compact EPS structures. Hence, developing novel strategies enhanced penetrability crucial. Herein, current progress nanotechnology methods to improve agents’ against matrix, regulating material morphology surface properties, utilizing physical penetration nano/micromotors microneedle patches, equipping nanoparticles degradation enzymes signal molecules, first summarized. Finally, challenges, perspectives, future implementations engineered delivery systems manage infections presented in detail.

Properties and Characterization Techniques of Graphene Modified Asphalt Binders

Nanomaterials, Journal Year: 2023, Volume and Issue: 13(5), P. 955 - 955

Published: March 6, 2023

Graphene is a carbon-based nanomaterial used in various industries to improve the performance of hundreds materials. For instance, graphene-like materials have been employed as asphalt binder modifying agents pavement engineering. In literature, it has reported that (in comparison an unmodified binder) Modified Asphalt Binders (GMABs) exhibit enhanced grade, lower thermal susceptibility, higher fatigue life, and decreased accumulation permanent deformations. Nonetheless, although GMABs stand out significantly from traditional alternatives, there still no consensus on their behavior regarding chemical, rheological, microstructural, morphological, thermogravimetric, surface topography properties. Therefore, this research conducted literature review properties advanced characterization techniques GMABs. Thus, laboratory protocols covered by manuscript are atomic force microscopy, differential scanning calorimetry, dynamic shear rheometer, elemental analysis, Fourier transform infrared spectroscopy, Raman electron thermogravimetric X-ray diffraction, photoelectron spectroscopy. Consequently, main contribution investigation state-of-the-art identification prominent trends gaps current state knowledge.

Antimicrobial Antioxidant Polymer Films with Green Silver Nanoparticles from Symphyti radix

Polymers, Journal Year: 2024, Volume and Issue: 16(3), P. 317 - 317

Published: Jan. 24, 2024

Antimicrobial natural polymer film with silver nanoparticles (AgNPs) biosynthesized using aqueous plant root extracts as reducing capping agents and for formatting show extensive applicability pathogenic microorganism problems. The formation of AgNPs was confirmed by transmission electron microscopy (TEM) scanning microscopy–energy-dispersive spectroscopy (SEM–EDS) techniques. antimicrobial activity biofilm green analysed inhibiting the growth Gram-negative Gram-positive bacteria culture Kirby–Bauer disk diffusion susceptibility test. Total phenolic content antioxidant were slightly higher in Sym. Radix than Radix/AgNPs. effect film/AgNPs against selected test cultures substantially more robust pure film. Pictures obtained TEM revealed presence spherical-shaped nano-objects an average size 27.45 nm. SEM–EDS studies uniform distribution metal throughout biopolymeric matrix. Morphological surface showed that films even, without holes or other relief irregularities. These apparent Symphyti radix film/AgNPs’ biological functions could provide a platform fighting era multi-drug resistance.
