and UV light grafting polymerization thermosensitive hydrogel. To confer
the application of this kind of material on biomedical, such as cell
attachment, Inter-penetrating Net-Work (IPN) thermosensitive hydrogel and
surface grafting poly(N-isopropyl acrylamide) (PNIPAAm) on gold
To make use of cold plasma copolymerization to deposition alcohol or
organosilicon polymer film on polystyrene (PS), and test the cell adherence.
PS change into hydrophilicity, and the cell adherence as well as tissue culture
polystyrene (TCPS) when cell culture macrophage and melanocyte after
isopropanol (IPA) plasma deposition. Besides graft poly acrylamide (PAAm)
by UV light, use the swelling character of PAAm to suck NIPAAm monomer
and prepare the sandwich like hydrogel IPN-(PAAm/PNIPAAm). Due to
there are still existence special characteristic of Lower Critical Solution
Temperature (LCST) about 32 of PNIPAAm. ℃ For this reason, take the
place of artificial musculature as a new model for irradiation experiments
using focused ultrasound.
The final of this investigate combine the front of two techniques, use
plasma treatment to produce free radicle. To take gold nanoparticle use cold
plasma glow discharge to produce free radicle after embellish of
11-Mercaptoundecanoic acid (MUA) that contact with carboxyl and thiol.
Subsequently use UV light grafting hydrogel monomer on gold nanoparticle.
Embellish gold nanoparticle surface steady, fast and convenient. As a result,
the color of Nano-Au(mua) is red wine, after O2 plasma treatment and then
grafting thermosensitive PNIPAAm is purplish red and
Nano-Au(mua)-g-PNIPAAm still have thermosensitive property.
