• poly
  • We describe size-selective semipermeable poly(ethylene glycol) (PEG) films which avoid the nonspecific absorption of large proteins but permit the passage of small target molecules. (ucl.ac.uk)
  • weights
  • Most studies that have investigated the interactions of tethered linear and star-shaped PEG layers with proteins have considered linear PEG molecules with molecular weights several orders of magnitude smaller than those considered for star-shaped PEG molecules (i.e. 10 000 g/mol vs. 200 000 g/mol, respectively).

  • chain
  • Segmented thermoplastic copolyester elastomers containing recurring polymeric long chain ester units derived from phthalic acids and long chain glycols and short chain ester units derived from phthalic acids and 1,4-butanediol or 1,4-butenediol. (google.com)
  • structure
  • By describing the relationship between the molecular structure and an important physiochemical property of surface-tethered PEG films, our findings on controllable semipermeable interfaces may be exploited for electrical sensor surfaces. (ucl.ac.uk)
