Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Comparison of Streptococcus mutans Adhesion with Different Concentrations in Artificial Saliva to Fixed Orthodontic Materials in Laboratory Conditions

open access: yesBiomedical and Biotechnology Research Journal
Background: Biofilm accumulation is a common complication of orthodontic treatment, occurring in approximately 60% of patients. The irregular surfaces of orthodontic appliances (archwires, brackets, and braces) create retention areas that hinder ...

E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure

open access: yesAdvanced Materials, EarlyView.
The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...

Effects of growth and starvation conditions on bacterial adhesion to plastic surfaces

open access: yesNational Science Open
The effects of nutrient conditions on the formation of plastisphere were unclear. This study investigated the impacts of growth and starvation conditions on the adhesion of both Gram-negative and Gram-positive bacteria to six plastics in both salt ...

An Ion‐Based Strategy Toward Synergistic Surface Functionalization Combining the Osteogenic Properties and NIR‐Mediated Antibacterial Activity of PEEK

open access: yesAdvanced Materials, EarlyView.
A multifunctional bioactive PEEK‐based implant (Mn@p/MBG‐SPEEK) is engineered to combat implant‐associated infections while promoting osteogenesis. The hybrid surface activates PI3K/Akt/mTOR and AP‐1 signaling pathways for osteogenic differentiation, while Mn coordination induces electronic coupling that narrows the HOMO‐LUMO energy gap and enhances ...

Boolean Logic‐Based Control Over Recombinant Protein Biomaterial Degradability and Therapeutic Delivery

open access: yesAdvanced Materials, EarlyView.
Fully recombinant protein‐based biomaterials execute complex Boolean logic for user‐programmable material degradation and concomitant therapeutic cargo release. Biologics, such as growth factors, can be incorporated within the crosslinkers as “drugamers”, while encapsulated cells can be released according to nested YES/OR/AND‐type logical operations ...
