Effect of amide hydrogen bonding on spontaneously formed gel-emulsions by two pyridyl carboxylic acid based amphiphiles, sodium salt of 2-dodecylpyridine-5-carboxylic acid and sodium salt of [2-dodecylpyridine-5-carboxylic]glycine: entrapment and release of vitamin B12

Fast and facile preparation of CTAB based gels and their applications in Au and Ag nanoparticles synthesis

“…However, all of the signature bands of pristine CTAB are not visible in the FTIR spectrum of the CTAB gel. The FTIR spectrum of the CTAB gel comprises of a wide band centred around 3377 cm -1 , which can be attributed to the stretched hydrogen bonded O-H groups, confirming the inter-molecular hydrogen bonding between water and surfactant [25]. Bands at 1378 and 1462 cm -1 , which are also present in the FTIR spectrum of n-hexane, can be assigned to CH 3 and CH 2 bending modes, respectively.…”

Self-assembled sorbitol-derived supramolecular hydrogels for the controlled encapsulation and release of active pharmaceutical ingredients

“…17 Other reports have controlled gelation using (e.g.) pH, 18 photoirradiation, 19 or crosslinking reactions 20 to trigger or inhibit drug release.…”

“…17 Other reports have controlled gelation using (e.g.) pH, 18 photoirradiation, 19 or crosslinking reactions 20 to trigger or inhibit drug release. Recently, we have worked with gelators based on the 1,3:2,4-dibenzylidene sorbitol (DBS) framework.…”

Unsaturation and Polar Head Effect on Gelation, Bioactive Release, and Cr/Cu Removal Ability of Glycolipids

“…The saturated solution of trypsin was prepared in water and added to the glycolipid formulations containing the bioactive at a concentration of 1 mg of trypsin per mg of glycolipid. Upon addition of enzyme, the mixture was mixed vigorously and subjected for kinetic spectrophotometric study at 37 °C . Herein, bioactive loaded gels are not 100% transparent, the time-dependent decrease in absorbance of the gel samples after the addition of trypsin is a measure of controlled delivery behavior.…”
