gelatin microspheres

Themed Section: Optimized Crosslinking of Gelatin

Gelatin microspheres must be crosslinked for biomedical applications Without this process the high solubility of the polymer in aqueous media prevents its use In most published studies on gelatin microspheres researchers have used analysis of terminal amino groups to determine the material's crosslinking degree Normally trinitrobenzenesulfonic acid (TNBS) is used for this purpose but

Preparation of Ethylcellulose Coated Gelatin Microspheres

Gelatin microspheres were then coated by ethylcellulose using a coacervation phase separation technique The idea for this approach was to prepare a delayed drug delivery system in which ethylcellulose protects particles for the first 6 h transit through the gastrointestinal tract However it was shown that this system could provide a suitable drug release pattern for colonic delivery of

Gelatin microspheres: influence of preparation parameters

Thermal hardening of gelatin microspheres Since gelatin microspheres quite rapidly swell and dissolve when poured in aqueous environments they cannot be suitable for sustained release of therapeutic agents requiring long release periods (up to a month) such as certain kinds of hormones and bioactive peptides (e g bromocriptine)2'17 In order to modify the microsphere matrix solubility and
