Biomimetic sharkskin surfaces with antibacterial, cytocompatible, and drug delivery properties.

Biomaterials advances
Fighting with the infection is one of the most challenging and costly burdens of the healthcare system. Several types of antibiotics and antibacterial agents have been designed and used in combating this dilemma. Nevertheless, the overuse of drugs an...

Chitosan-gum arabic embedded alizarin nanocarriers inhibit biofilm formation of multispecies microorganisms.

Carbohydrate polymers
Biofilm formation by microorganisms is a serious clinical problem that leads to drug failure. Nanocarriers (NCs) have shown good potential for controlling drug-resistant biofilms, although the effective penetration and retention of NCs in biofilms is...

Antibiofilm activity of glycolic acid and glyoxal and their diffusion-reaction interactions with biofilm components.

Food research international (Ottawa, Ont.)
Biofilms on food-contact surfaces act as potential reservoirs of microbial pathogens and can cause operational problems. The search for effective biofilm control agents is a significant research need. In this study, glycolic acid (GA) and glyoxal (GO...

Combined effects of volume ratio and nitrate recycling ratio on nutrient removal, sludge characteristic and microbial evolution for DPR optimization.

Journal of environmental sciences (China)
The optimization of volume ratio (V/V/V) and nitrate recycling ratio (R) in a two-sludge denitrifying phosphorus removal (DPR) process of Anaerobic Anoxic Oxic-Moving Bed Biofilm Reactor (A/O-MBBR) was investigated. The results showed that prolonged ...

Epigallocatechin gallate has antibacterial and antibiofilm activity in methicillin resistant and susceptible of different lineages in non-cytotoxic concentrations.

Natural product research
is an opportunistic agent that can cause a variety of infections, both hospital and community-acquired. Epigallocatechin gallate (EGCG), a flavonoid present in the leaves of , has different biological activities, including antimicrobial potential. H...

Swarming Aqua Sperm Micromotors for Active Bacterial Biofilms Removal in Confined Spaces.

Advanced science (Weinheim, Baden-Wurttemberg, Germany)
Microscale self-propelled robots show great promise in the biomedical field and are the focus of many researchers. These tiny devices, which move and navigate by themselves, are typically based on inorganic microstructures that are not biodegradable ...

Misic, a general deep learning-based method for the high-throughput cell segmentation of complex bacterial communities.

eLife
Studies of bacterial communities, biofilms and microbiomes, are multiplying due to their impact on health and ecology. Live imaging of microbial communities requires new tools for the robust identification of bacterial cells in dense and often inter-...

Evaluation of the Effect of Comprehensive Nursing Interventions on Plaque Control in Patients with Periodontal Disease in the Context of Artificial Intelligence.

Journal of healthcare engineering
Plaque is a bacterial biofilm that adheres to each other and exists on the tooth surface, and new plaque can continuously reform after removing it from the tooth surface. The pathogenesis of periodontal disease is related to the bacteria, the host an...

Enzyme-Photocatalyst Tandem Microrobot Powered by Urea for Escherichia coli Biofilm Eradication.

Small (Weinheim an der Bergstrasse, Germany)
Urinary-based infections affect millions of people worldwide. Such bacterial infections are mainly caused by Escherichia coli (E. coli) biofilm formation in the bladder and/or urinary catheters. Herein, the authors present a hybrid enzyme/photocataly...

Artificial Intelligence-Driven Image Analysis of Bacterial Cells and Biofilms.

IEEE/ACM transactions on computational biology and bioinformatics
The current study explores an artificial intelligence framework for measuring the structural features from microscopy images of the bacterial biofilms. Desulfovibrio alaskensis G20 (DA-G20) grown on mild steel surfaces is used as a model for sulfate ...
