gelatin microspheres

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 CiteSeerX - Document Details (Isaac Councill Lee Giles Pradeep Teregowda): In this study we developed novel microspheres comprised of an apatite-gelatin nanocomposite This microsphere formulation is considered to be useful as a bone regenerative filler either directly or combined with polymeric matrices Using the water-in-oil emulsion technique the apatite-gelatin viscous

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

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

Trisacryl gelatin microspheres were negative with periodic acid-Schiff and orange-pink with Movat stains whereas PVA was positive with periodic acid-Schiff and black with Movat Our study the largest histologic analysis to date confirms and extends the observations of earlier studies of trisacryl gelatin microspheres In addition we conclude that as expected the histologic appearance of

Gelatin microspheres are prepared by cross-linking gelatin in water in oil emulsion with glutaraldeh yde by coac ervation phase separ ation method The shape of the microspheres prepared by this method is spherical 2 The aim of this work was to prepare sustained release microcapsules of Salbutamol sulphate by Thermal Change method and evaluation of the prepared microcapsules3 Materials and
