Application

  • Photocurable Bioink for the Inkjet 3D Pharming of Hydrophilic Drugs.: This research discusses the development of a photocurable bioink using poly(ethylene glycol) dithiol for the inkjet 3D printing of hydrophilic drugs. The study highlights the biocompatibility and potential applications in drug delivery systems (Acosta-Vélez et al., 2017).
  • Enhanced mechanical properties of photo-clickable thiol-ene PEG hydrogels through repeated photopolymerization of in-swollen macromer.: This study examines the use of poly(ethylene glycol) dithiol in creating thiol-ene hydrogels with enhanced mechanical properties. The repeated photopolymerization technique improves the hydrogel′s stability and applicability in medical devices and tissue engineering (Fiedler et al., 2016).
  • Degradative properties and cytocompatibility of a mixed-mode hydrogel containing oligo[poly(ethylene glycol)fumarate] and poly(ethylene glycol)dithiol.: The paper explores the degradative behavior and cytocompatibility of hydrogels composed of oligo[poly(ethylene glycol)fumarate] and poly(ethylene glycol)dithiol. The findings indicate favorable biocompatibility and potential for biomedical applications such as drug delivery and tissue engineering (Brink et al., 2009).
