Multifunctional Composite Hydrogels for Bacterial Capture, …
网页2022年10月12日 · Hydrogels functionalized with BCEs are typically composite hydrogels developed for rapid bacterial identification with subsequent downstream functions such as (i) antibacterial activity either by releasing the encapsulated antibacterial agent or due to the inherent antibacterial nature of the hydrogel or (ii) bacterial sensing for identifying ...
Hydrogels: An overview of its classifications, properties, and ...
网页2023年11月1日 · Hydrogel structure consists of a solid polymer network matrix called ‘mesh’ and bounded interstitial water or biological fluid. The matrix phase holds fluid and imparts elasticity to the hydrogel by expansion and contraction. The fluid phase makes hydrogel wet and soft by filling network interstitial sites.
