Surface Acoustic Waves-Enabled Shielding Fluid Layers Inhibit Bacterial Adhesion.
Langmuir
December 2024
Article Synopsis
- Surface acoustic waves (SAW) generated by piezoelectric devices are gaining interest for their potential to prevent bacterial adhesion on surfaces, though the exact mechanisms remain unclear.
- This study investigates how SAW-induced boundary-driven streaming affects bacterial attachment in liquid environments, focusing on the creation of micrometer-scale fluid layers that shield against bacteria.
- Experiments and simulations reveal that the viscous boundary layer and vortices created by SAW can reduce bacterial colonization and biofilm formation, highlighting new strategies for antibacterial applications.
Article Synopsis
- - The study focuses on the synthesis of perfluoro-butyl secondary amines, which have various potential applications but are challenging to produce.
- - The authors introduce an efficient method for synthesizing these amines directly from readily available trifluoromethyl secondary amines, involving three key chemical reactions.
- - This new approach utilizes only one trifluoromethyl source, effectively eliminates hydrogen fluoride, and is compatible with different functional groups, making it a promising technique, especially for medical imaging applications.
Article Synopsis
- The CIBMTR's 2023 summary slides now include data on CAR-T therapy and patient-reported outcomes (PROs), enhancing the understanding of transplantation trends.
- The CIBMTR launched a PRO data collection protocol in August 2020 to gather insights from adult hematopoietic cell transplantation (HCT) and CAR-T recipients at participating centers.
- As of September 2023, PRO data from 993 patients across 25 centers have been collected and integrated with clinical data to improve patient care and support comprehensive research.
Disregarded Free Chains Affect Bacterial Adhesion on Cross-Linked Polydimethylsiloxane Surfaces.
ACS Appl Mater Interfaces
August 2023
The surface properties exhibited by chemically cross-linked polydimethylsiloxanes (CPDMS) such as morphology, stiffness, and wettability have garnered great interest in the study of bacteria-material interactions. Nevertheless, the hidden factor of uncross-linked free PDMS chains that dissociate in CPDMS has often been overlooked when studying the biofilm formation on these polymeric elastomer surfaces. Here, we undertake a comparative characterization of the effects of free chains in CPDMS on bacterial adhesion to both flat and textured Sharklet CPDMS surfaces.
