Hydrogels are soft, water-rich polymeric materials that can swell or shrink in response to environmental stimuli. This ability to change shape makes them valuable in miniaturized devices for flexible ...

However, most current hydrogel pores use circular designs, which limit control over shape change and lead to unpredictable, slow actuation. They often close unevenly and recover poorly, reducing their ...

Each year, bacterial infections are responsible for roughly 7.7 million deaths worldwide, with this problem further exacerbated by rising antibiotic resistance. Not only are wound infections ...

A gelatinous substance that would otherwise be waste from a nut often used to make herbal tea can be made into a hydrogel with all different biomedical uses, University of Chicago researchers recently ...

Bioengineers have developed a first-of-its-kind hydrogel for second-degree burns that can be dissolved quickly and easily for wound dressing changes using a solution that breaks apart the ...

Gelatin interacts with cells through the presence of arginine-glutamine-aspartic acid (R-G-D) sequences in its protein backbone, and it is also enzymatically degradable. 1 Gelatin is a cost-effective ...

Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a ...

The proposed strategy utilizes facet-and-hinge architectures to guide the swelling of facets in polygonal pores along predefined directs, enabling precise control over pore closure and restoration.
