We investigated the effect of two brush parameters, thickness and dispersity in molecular weight distribution, on adhesion bacteria to pH-responsive poly(acrylic acid) (PAA) brushes synthesized using surface-initiated atom transfer radical polymerization. The attachment detachment Staphylococcus epidermidis PAA at pH 4 9, respectively, were examined with confocal microscopy. An optimal range thickness, 13-18 nm, was identified for minimizing bacterial 4, did not depend dispersity. Increasing...
Adhesion of bacteria to interfaces is the first step in pathogenic infection, biofilm formation, and bioremediation oil spills other pollutants. Bacteria use a variety surface structures promote interfacial adhesion, with level expression these varying response local conditions environmental signals. Here, we investigated how overexpression type 1 fimbriae, one such appendage, modifies ability Escherichia coli adhere solid substrates, via formation yeast agglomeration, oil/water interfaces,...
We investigate the effect of interfacial properties on adhesion bacteria at oil/water interfaces using confocal microscopy. Surfactant-decorated dodecane droplets diameter 20-60 μm are generated a coflow microfluidic device, introduced into an aqueous saline suspension Marinobacter hydrocarbonoclasticus bacteria, and imaged in 3-D over time. Using image analysis algorithms, we determine number adhering time presence dioctyl sodium succinate (DOSS), component dispersant used oil-spill...
Adhesion of marine bacteria onto the oil–water interface is enhanced by motility.
Oil droplets suspended near a liquid–solid interface can be driven to rotate by motile bacteria adhered the droplet surface.
We examined the effects of alkyl carbon spacer length (CSL) and molecular weight on fouling resistance release properties zwitterionic poly(sulfobetaine methacrylate) brushes. Using surface-initiated atom transfer radical polymerization, we synthesized two series brushes with CSL = 3 4 from 19 to 1500 kg ·mol–1, corresponding dry brush thickness around 6 180 nm. The was nearly completely wet water (independent weight), whereas exhibited a strong increase in contact angle weight. Though...
Marine bacteria form small aggregates in the presence of an anionic surfactant, dioctyl sodium sulfosuccinate, and calcium ions.
expresses surface appendages including fimbriae, flagella, and curli, at various levels in response to environmental conditions external stimuli. Previous studies have revealed an interplay between expression of fimbriae flagella several
The interactions between bacterial pathogens and host cells are characterized by a multitude of complexities, leading to wide range heterogeneous outcomes. Despite extensive research, we still have limited understanding how motility in complex environments impacts their ability tolerate antibiotics adhere mammalian cell surfaces. challenge lies unraveling the complexity these developing quantitative microscopy approaches predict behavior populations.
