hydrogels are completely non toxic and are used during surgery to help repair human tissue. the first law of medicine is "above all do no harm" (a law big pharma violates at every opportunity) and at least this wont hurt anyone. i mean if someone wants to ingest a totally non toxic gel to help them cut down on food intake, i say - why not?
in fact it may actually improve digestion and elimination since this will end up delivering lots of water to the intestines, and since most ppl are dehydrated anyway.
this really doest sound so bad to me at all. i have seen MUCH worse ideas.
* Currently used as scaffolds in tissue engineering. When used as scaffolds, hydrogels may contain human cells in order to repair tissue.
* environmentally sensitive hydrogels. These hydrogels have the ability to sense changes of pH, temperature, or the concentration of metabolite and release their load as result of such a change.
* as sustained-release delivery system
* provide absorption,desloughing and debriding capacities of necrotics and fibrotic tissue.
* hydrogels that are responsive to specific molecules, such as glucose or antigens can be used as biosensors as well as in DDS.
* In disposable diapers where they "capture" urine, or in sanitary towels
* Contact lenses (silicone hydrogels, polyacrylamides)
* medical electrodes using hydrogels composed of cross linked polymers (polyethylene oxide, polyAMPS and polyvinylpyrrolidone)
Other, less common uses include:
* Breast implants
* Granules for holding soil moisture in arid areas
* Dressings for healing of burn or other hard-to-heal wounds. Wound GEL are excellent for helping to create or maintain environment.
