Degradable sugar-based polymers may store and release useful molecular freight — ScienceDaily

Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are degradable through acid hydrolysis. The researchers also integrated “cargo” molecules in the polymer, which are designed to split off after polymer degradation. Degradable, cargo-bearing polymers […]

Latch, load and release: Elastic motion makes click beetles click, study finds

Cellulose nanofibril-based encapsulation structure to control drug release

The design of MPDA@GO/CNF encapsulation structure and the application for controlled drug release. Credit: LIU Yingying Intelligent hydrogels with multiple functions such as sustained drug release abilities with low burst release, antibacterial properties, and biocompatibility are highly desirable in the biomaterials fields, particularly for cellulose-based drug carriers. “Despite the nanocellulose-based hydrogels, which are promising for […]
