Diffusion in Biofilms [PDF]

open access: yesJournal of Bacteriology, 2003
Much of what makes life in a microbial biofilm different from life in a free aqueous suspension can be explained by invoking the phenomenon of diffusion. This article discusses the profound influence of the physics of the diffusion process on the chemistry and biology of the biofilm mode of growth.

Development of Substrate‐Independent Antifouling and Bactericidal Surfaces Using Visible Light Cross‐Linked Hydrogel Coatings for Biomedical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
A new antifouling, antithrombogenic, and bactericidal hydrogel coating method is developed for implantable medical devices. The hydrogel coating can be easily formed by visible‐light crosslinking and is universally applicable to all substrates, ranging from polymers to metals.

Precision Photothermal Therapy at Mild Temperature: NIR‐II Imaging‐Guided, H2O2‐Responsive Stealth Nanobomb

open access: yesAdvanced Healthcare Materials, EarlyView.
The new generation nanobomb, termed the stealth nanobomb, is fabricated through self‐assembly using a polymeric carbon monoxide carrier (PLGA(CO)), small molecule near‐infrared‐active agents (2TT‐OC46B), and phospholipid polyethylene glycol (DSPE‐mPEG2000). The stealth nanobomb can circulate in the bloodstream and specifically target pancreatic cancer,

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

open access: yesAdvanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Biofilm Development

open access: yesMicrobiology Spectrum, 2015
ABSTRACT During the past decade we have gained much knowledge about the molecular mechanisms that are involved in initiation and termination of biofilm formation. In many bacteria, these processes appear to occur in response to specific environmental cues and result in, respectively, induction or termination of biofilm matrix production via ...
