Cryogels based on chitosan (a substance derived from crab shells) have been developed at Novosibirsk State Technical University (NSTU). This was reported by the university's press service.
Cryogels have a highly porous structure and improved absorption properties.
If a regular hydrogel contains pores with a size of several hundred micrometers, then a cryogel forms a highly porous structure with an abundant number of pores ranging from 10 to 30 micrometers.
Cryogels can absorb and release more moisture compared to hydrogels.
Cryogels, like other types of gels, do not require additional disposal measures and are safe for the environment. After fulfilling their purpose, they naturally decompose without causing any harm to the environment.
New chitosan-based cryogels can be used in medicine and agriculture.
Earlier www1.ru reported that a new chitosan-based filter was developed in Novosibirsk.
