Biofilm Removal Using Bubbles and Sound
Bacteria in biofilms adhere well to surfaces and are quite difficult to remove. Oral plaque is one example of a biofilm. Many researchers have studied ways to remove plaque and bacteria from surfaces. It has been found that the passage of a bubble across a surface to which bacteria has adhered can …

Biofilm Removal with Acoustic Cavitation and Lavage
<p>Bacterial biofilm colonies attached to orthopedic implants, and surrounding tissues resist to antibiotic treatments, prolong hospitalization, increase mortality, and usually require the removal and replacement of the entire joint. Through acoustic cavitation, it could be possible to remove the …

Development of novel bacteriophagebased products for biofilm removal
El aumento gradual de la resistencia a los antibióticos en bacterias patógenas es una de las mayores amenazas a día de hoy, no solo afectando a la salud humana, sino también a la economía mundial, estimándose que el tratamiento de la resistencia a los antibióticos podría costar billones a la …

Design of multidimensional microplasma array for biofilm removal and dynamic photonic crystals
… arrays and understanding their interactions with biofilms and electromagnetic waves. Biofilms are ubiquitous in municipal drinking water distribution systems, and they present significant human health concerns because they often harbor pathogens. Biofilms serve as pathogen reservoirs by supplying …

Effectiveness of GentleWave CleanFlow on Multispecies Endodontic Biofilm Removal in Single Rooted Extracted Teeth
… root canal treatment is disinfection. Bacterial biofilms adhere to canal walls and invade the intricate anatomy present within root canal systems. Traditional irrigation methods are unable to deliver irrigation solutions to all parts of the canal system. The GentleWave system is an advanced …

Comparative Efficacy of MUS System vs Er:YAG Laser System in Reducing Bacterial Biofilms in Root Canals
… in vitro study aimed to evaluate the efficacy of biofilm removal using two advanced irrigation systems: the Multisonic Ultracleaning System (MUS) GentleWave® with the CleanFlow™ handpiece, and the erbium-doped yttrium-aluminum-garnet (Er:YAG) laser (LightWalker® Fotona) for Laser-Activated …

Investigation of Advanced Cavitation Agents for Nanoparticle-Mediated Histotripsy (NMH) Applications
… as prostate cancer ablation and catheter-based biofilm removal. However, its full potential as a multifunctional therapeutic platform for more complex disease environments remains underexplored. In this dissertation, I investigate the feasibility and optimization of NMH for two clinically …

Arsenic Release from Chlorine Promoted Oxidation of Pyrite in the St. Peter Sandstone Aquifer, Eastern Wisconsin
… impacted wells for well disinfection and biofilm removal. In order to provide information pertaining to WDNR's recommendations, St. Peter sulfide minerals were reacted with a range of chlorine "shock-treatments" similar to those occurring in wells. This study focuses on abiotic processes …

Evaluation of a Typical CIP Protocol to Control Bacterial Biofilms on Whey Reverse Osmosis Membranes
… premature replacement of membranes. Bacterial biofilms developed on reverse osmosis membranes cause severe flux decline during whey process1ng. Our previous studies provided clear evidence of mixed species biofilms on the membranes obtained from a commercial whey processing plant. Presence of …

Optimising the plastic optical fibre evanescent field biofilm sensor
… was demonstrated reacting to a real measurand eg biofilm in which initial growth affects the optical properties at the core cladding interface by refractive index modulation. This sensor was capable of measuring biofouling and scaling at water interfaces. The sensor was trialled in a European …

Effects of Surface Topography on Bacterial Biofilm Formation
<p>Biofilms are multicellular structures with bacterial cells attached to a surface and embedded in an extracellular matrix. With high-level resistance to antimicrobial agents, biofilms are the cause of chronic infections associated with implanted medical devices such as breast implants, orthopedic …

Design and Development of an Anti-fouling Urinary Catheter Utilizing Active Surface Deformation
… and make up to 40% of nosocomial infections. Biofilms on urinary catheters are critical to the progression of symptomatic CAUTIs, but are difficult to treat due to the protective effect of the biofilm matrix against antibiotics. The anti-fouling catheter technology proposed and demonstrated …

The dynamics of surface detachment and quorum sensing in spatially controlled biofilm colonies of Pseudomonas aeruginosa
Biofilms represent a highly successful life strategy of bacteria in a very broad range of environments and often have negative implications for industrial and clinical applications, as their removal from surfaces and the prevention of biofouling in the first place represent formidable and to date …

Antibiofilm properties of selected Lactobacillus species and their mechanism of action against Listeria monocytogenes
… by the fact that L. monocytogenes forms biofilms, one very powerful virulence mechanism, that adhere to processing surfaces. The shortfall of commonly used antibiotics and sanitizers as treatment against L. monocytogenes biofilms due to antimicrobial resistance leads to a major safety …
