A supramolecular approach for converting renewable biomass into functional materials

“…The biocompatibility and cytotoxicity of poly[TA] were investigated via in vitro cell experiments. 49,57 NIH 3T3 fibroblast cells were treated with poly[TA] and poly[TA-biomass]s at different concentrations for 1 day and 3 days, respectively, to evaluate their biocompatibility. As shown in Fig.…”

Biological applications of lipoic acid-based polymers: an old material with new promise

“…Furthermore, PDA's catechol groups can establish strong contact with proteins and cells, thereby promoting cell attachment and proliferation. Cui et al 65 created a self-stabilized deep eutectic supramolecular polymer adhesive by heating a mixture of LA and LA-Na (S-, R-isomer, racemate) with LA in one step. When the LA/LA-Na ratio was 2, the adhesion strength of the adhesive was increased significantly in water, from 137 kPa to 1.07 Mpa after soaking in water for 1 day.…”

A Biodegradable Supramolecular Adhesive with Robust Instant Wet Adhesion for Urgent Hemostasis and Wound Repair

“…In the 1 H NMR spectra of polyLA-PEGDA-PLGA, an absorption peak at 8.28-8.40 ppm was observed, signifying the amidation reaction between the -NH 2 group of ɛ-PL and the -COOH group of polyLA. [24,25] Raman spectroscopy showed a splitting of the peak at 510 cm −1 in LA into two peaks at 508 cm −1 and 524 cm −1 in the adhesive (Figure S3, Supporting Information), indicating the complete polymerization of LA, reinforcing the cohesive forces within the adhesive network. [26] Additionally, X-ray photoelectron spectroscopy (XPS) revealed the presence of phenolic and quinone functional groups in the adhesive (Figure S4, Supporting Information).…”
