The researchers also devised a method to strongly bond the hydrogel
to various nonporous surfaces.
As mentioned above, introduction of second cross-linked network and the addition of reinforcing fillers were both considered to be effective methods to improve the mechanical performance of the hydrogel
SpaceOAR patients experienced a significant reduction in rectal radiation dose and severity of late rectal toxicity when compared to control patients who did not receive SpaceOAR hydrogel
The effects of hydrogel
particle encapsulation on the physical location, chemical stability and lipase digestibility of emulsified polyunsaturated lipids--fish oil--were investigated.
samples were moulded into dumbbell shape in accordance to ASTM Standard Method D638-04, and the length, breath and thickness of each sample recorded.
BSA and doxycycline release from our hydrogels
followed the power law model of drug release and revealed that the addition of ELP resulted in a composite hydrogel
with a more gradual bioactive agent release.
Like gelatin, early versions of the hydrogels
would fall apart, whereas human hearts are elastic.
Another experiment showed that the hydrogel
could be successfully and stably synthesized within the channels of a microfluidic device.
Irradiation with UV not only enhanced overall L-DOPA release from the hydrogel
, but also caused an extra 'explosive' release five hours after irradiation.
Both CSPH and SPHC possessed large numbers of pores, indicating that formation of hydrogel
would not destroy the superporous structure.
The recipe for the new hydrogel
is quick and relatively easy.
Erhan and ARS chemist Zengshe Liu developed the hydrogel
in studies at ARS's National Center for Agricultural Utilization Research in Peoria.
