Biofilms are the cause of 80% of microbial infections. species have emerged as multi- and pan-drug-resistant bacteria and pose a great threat to human health. These act as nosocomial pathogens and form excellent biofilms, both on biotic and abiotic surfaces, leading to severe infections and diseases. Various methods have been developed for treatment and control of biofilm including photodynamic therapy, radioimmunotherapy, prophylactic vaccines and antimicrobial peptides. Nanotechnology, in the present scenario, offers a promising alternative. Nanomaterials possess unique properties, and multiple bactericidal mechanisms render them more effective than conventional drugs. This review intends to provide an overview of biofilm and the significant role of various nanoparticles as anti-biofouling agents, surface-coating materials and drug-delivery vehicles for biofilm control and treatment of infections.

This work investigated the effect of zinc oxide nanoparticles functionalized with curcumin (ZnO+CUR) supplementation during the maturation (IVM) of bovine oocytes on the embryo production and the cellular antioxidant response. A total of 1,625 cumulus-oocyte complexes (COCs) were cultured in the maturation medium in the absence (0 µM - control) or presence of different concentrations of ZnO+CUR (3 µM, 6 µM or 12 µM). After IVM, COCs were destined either to 1) embryo production or 2) analysis of reactive oxygen species production, superoxide dismutase (SOD) activity, catalase (CAT) activity and total antioxidant capacity (FRAP).

A novel magnetic nanostructured molecularly imprinted polymer probe (FeO@MIP) was developed for the continuous detection of Ti/Fe. The synthesis employed 50 nm FeO nanoparticles as the core matrix, with Ti and Fe serving as template molecules. Functional monomers α-methylacrylic acid (MAA) and acrylamide (AM) were used, along with ethylene glycol dimethacrylate (EGDMA) as the crosslinking agent and 2,2'-azobisisobutyronitrile (AIBN) as the polymerization initiator, utilizing a microwave-assisted procedure.

Synthetic dyes, such as Congo red (CR), pose serious threats to human health and aquatic ecosystems because of their carcinogenicity and resistance to degradation, necessitating the development of efficient and eco-friendly remediation strategies. In this study, silver nanoparticles (AgNPs) were synthesized via a green method using Ocimum sanctum (holy basil) leaf extract and applied for CR dye removal from aqueous solutions. The adsorption process was optimized using response surface methodology (RSM) based on Box-Behnken design (BBD), evaluating the influence of key parameters including pH, AgNP dosage, initial dye concentration, contact time, and temperature.

Salmonella Typhimurium (S. Typhimurium) is one of the most common food-borne diseases, highlighted as the top food-borne bacterial pathogen in the world with a low infectious dose (1 CFU) and high mortality rate. It is commonly associated with numerous foods such as dairy products, protein sources (multiple types of meat, poultry, and eggs), and bakery products.

Background: Organic chemicals have been known to cause allergic diseases such as bronchial asthma and hypersensitivity pneumonitis; however, the possibility that they do not cause irreversible pulmonary fibrosis has not been considered. Polyacrylic acid (PAA), an organic chemical, has caused irreversible progressive pulmonary fibrosis in exposed workers, indicating its potential to induce pulmonary inflammation and fibrosis. Although intratracheal instillation studies are commonly used for evaluating lung pathology, traditional methods face challenges with chemical substances, particularly nanoparticles, which tend to aggregate in suspension and prevent uniform pulmonary distribution.
