- 論文の詳細を見る
Poly(ethylene glycol)-functionalized silsesquioxane acrylate (PEG-SSQA) has been developed as antibiofouling material for nanostructure-based biomedical applications. PEG-SSQA was synthesized from the hydrolytic condensation of trimethoxysilanes with PEG and acrylate groups. From the NMR spectra, the PEG-SSQA was observed to be a mixture of random, ladder, and cage structures. The cured PEG-SSQA exhibits hydrophilicity (water contact angle: 26.6--34.7°), low swelling ratios in water ({< }1.8 wt %) and organic solvents ({<} 3 wt %), a high UV transparency ({> }90% at 365 nm), a high Young's modulus (ca. 1 GPa), and low shrinkage ({<} 4.2% in height). PEG-SSQA possessed the ability to form sub-25 nm features. In addition, the cured PEG-SSQA films with long-term stability under chemical and biological stress showed strong resistance to the nonspecific adsorption of proteins. These characteristics may offer a new strategy for the development of a number of biomedical applications, such as nanobiodevices, nanobiosensors and labs-on-a-chip.
