Nanomaterials with a photothermal effect for antibacterial activities: an overview

Nanoscale, Год журнала: 2019, Номер 11(18), С. 8680 - 8691

Опубликована: Янв. 1, 2019

Nanomaterials and nanotechnologies have been expected to provide innovative platforms for addressing antibacterial challenges, with potential even deal bacterial infections involving drug-resistance. The current review summarizes recent progress over the last 3 years in field of nanomaterials a photothermal conversion effect. We classify these into four functional categories: carbon-based nanoconjugates graphene derivatives or carbon nanotubes, noble metal mainly from gold silver, metallic compound nanocomposites such as copper sulfide molybdenum sulfide, polymeric well other nanostructures. Different categories can be assembled each enhance effects activities. describes their fabrication processes, unique properties, modes, healthcare applications.

Responsive and Synergistic Antibacterial Coatings: Fighting against Bacteria in a Smart and Effective Way

Advanced Healthcare Materials, Год журнала: 2019, Номер 8(3)

Опубликована: Янв. 4, 2019

Abstract Antibacterial coatings that eliminate initial bacterial attachment and prevent subsequent biofilm formation are essential in a number of applications, especially implanted medical devices. Although various approaches, including bacteria‐repelling bacteria‐killing mechanisms, have been developed, none them entirely successful due to their inherent drawbacks. In recent years, antibacterial responsive the microenvironment, possess two or more killing triggered‐cleaning capability emerged as promising solutions for infection contamination problems. This review focuses on progress three types such synergistic coatings, i) self‐defensive which can “turn on” biocidal activity response bacteria‐containing microenvironment; ii) mechanisms interact synergistically reinforce each other; iii) smart “kill‐and‐release” switch functionality between bacteria releasing under proper stimulus. The design principles potential applications these discussed brief perspective remaining challenges future research directions is presented.

A Mini Review of Antibacterial Properties of ZnO Nanoparticles

Frontiers in Physics, Год журнала: 2021, Номер 9

Опубликована: Март 11, 2021

The development of antibiotic resistance bacteria is one the most pressing problems in world health care. One promising ways to overcome microbial antibiotics use metal nanoparticles and their oxides. In particular, numerous studies have shown high antibacterial potential zinc oxide (ZnO-NP) relation gram-positive gram-negative bacteria. This mini-review includes an analysis results recent years aimed at studying activity based on oxide. dependence effect size applied E. coli S. aureus given. influence various synthesis main types modifications NP-ZnO increase efficiency are also considered.

Nanomaterials and nanotechnology for the delivery of agrochemicals: strategies towards sustainable agriculture

Journal of Nanobiotechnology, Год журнала: 2022, Номер 20(1)

Опубликована: Янв. 4, 2022

Nanomaterials (NMs) have received considerable attention in the field of agrochemicals due to their special properties, such as small particle size, surface structure, solubility and chemical composition. The application NMs nanotechnology dramatically overcomes defects conventional agrochemicals, including low bioavailability, easy photolysis, organic solvent pollution, etc. In this review, we describe advances pesticides fertilizers, which are two earliest most researched areas agrochemicals. Besides, article concerns with new applications other bio-pesticides, nucleic acid pesticides, plant growth regulators (PGRs), pheromone. We also discuss challenges industrialization trend Constructing nano-agrochemical delivery system via facilitates improvement stability dispersion active ingredients, promotes precise reduces residual pollution decreases labor cost different scenarios, is potential maintain sustainability agricultural systems improve food security by increasing efficacy inputs.

Antibacterial Nanomaterials: Mechanisms, Impacts on Antimicrobial Resistance and Design Principles

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(17)

Опубликована: Янв. 31, 2023

Antimicrobial resistance (AMR) is one of the biggest threats to environment and health. AMR rapidly invalidates conventional antibiotics, antimicrobial nanomaterials have been increasingly explored as alternatives. Interestingly, several show AMR-independent effects without detectable new therefore suggested prevent evolution. In contrast, some are found trigger evolution AMR. Given these seemingly conflicting findings, a timely discussion two faces urgently needed. This review systematically compares killing mechanisms structure-activity relationships antibiotics nanomaterials. We then focus on nano-microbe interactions elucidate impacts molecular initiating events Finally, we provide an outlook future propose design principles for prevention
