Cyclic Olefin Copolymers as Versatile Materials for Advanced Engineering Applications

Advanced Functional Materials, EarlyView.
Cyclic olefin copolymers (COCs) are presented as highly versatile materials combining tunable synthesis, excellent optical properties, and mechanical robustness. Their potential spans microfluidics, bioengineering, and advanced electronics, while emerging self‐healing and sustainable solutions highlight future opportunities.

Intermittent antibiotic exposure of Escherichia coli biofilms drives resistance in catheter-associated infection models

npj Biofilms and Microbiomes
The use of antibiotic lock therapy (ALT) to protect catheters from infection is still being debated due to its inconsistent effectiveness and the potential risk of promoting antibiotic resistance.

Biofilms for babies: introducing microbes and biofilms to preschool-aged children [PDF]

, 2017
Microbes are beneficial to life on our planet as they facilitate natural processes such as global nutrient cycling in our environment. This article details a 30-minute activity to introduce pre-school children ranging from 3 to 5 years of age to microbes

Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents

Advanced Healthcare Materials, EarlyView.
Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Biofilm released cells can easily be obtained in a fed-batch system using ica+ but not with ica- isolates [PDF]

PeerJ, 2020
Staphylococcus epidermidis is one of the major opportunistic bacterial pathogens in healthcare facilities, mainly due to its strong ability to form biofilms in the surface of indwelling medical devices.

Electrochemical micro-structuring of graphite felt electrodes for accelerated formation of electroactive biofilms on microbial anodes. [PDF]

, 2011
Electroactive biofilms were formed on graphite felt anodes under constant potential polarisation using compost leachate as the inoculum and dairy waste as the substrate. A new surface treatment is presented that consists of creating micro-cavities on the

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

Acid tolerance in early colonizers of oral biofilms

BMC Microbiology, 2021
Background In caries, low pH drives selection and enrichment of acidogenic and aciduric bacteria in oral biofilms, and development of acid tolerance in early colonizers is thought to play a key role in this shift.

Dynamic energy budget approach to evaluate antibiotic effects on biofilms [PDF]

, 2017
Quantifying the action of antibiotics on biofilms is essential to devise therapies against chronic infections. Biofilms are bacterial communities attached to moist surfaces, sheltered from external aggressions by a polymeric matrix.

Airborne 1O2 Delivery via a Superhydrophobic Dressing as a Pathway to Next‐Generation Wound Therapies, an in Vivo Murine Burn Model Study

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the SH bandage placed on an infected burn wound and its role in wound healing. A superhydrophobic PDMS membrane coated with the PS verteporfin is placed over the wound area and illuminated with a red laser at 690 nm, generating airborne 1O2 above the tissue.
