Copper alloys to prevent bacterial biofilm formation on touch surfaces

Usnic acid, a natural antimicrobial agent able to inhibit bacterial biofilm formation on polymer surfaces.

In modern medicine, artificial devices are used for repair or replacement of damaged parts of the body, delivery of drugs, and monitoring the status of critically ill patients. However, artificial surfaces are often susceptible to colonization by bacteria and fungi. Once microorganisms have adhered to the surface, they can form biofilms, resulting in highly resistant local or systemic infection...

Biofilm Formation on Restored Root Surfaces

Biofilm Formation on Polymeric Heat Transfer Surfaces

The biofouling affinity on different polymeric surfaces (PP, PSU, PET, PEEK) in comparison with SS 1.4301 was studied using the model bacterium E.coli K12 DSM 498. A test rig with seven identical chambers allowed investigations at different system conditions (throughputs, inclination of the heat transfer cell, etc.). The biofilm mass deposited on the polymer surfaces was several magnitudes smal...

Microfluidic approaches to bacterial biofilm formation.

Bacterial biofilms-aggregations of bacterial cells and extracellular polymeric substrates (EPS)-are an important subject of research in the fields of biology and medical science. Under aquatic conditions, bacterial cells form biofilms as a mechanism for improving survival and dispersion. In this review, we discuss bacterial biofilm development as a structurally and dynamically complex biologica...

Bacterial Biofilm Formation on Resorbing Magnesium Implants

Background: Implant-associated infections are a result of bacterial adhesion to an implant surface and subsequent biofilm formation at the implantation site. This study compares different magnesium materials based on their ability to resist bacterial adhesion as well as further biofilm formation. Material and Methods: The surfaces of four magnesium-based materials (Mg2Ag, Mg10Gd, WE43 and 99.99...
