WebThe two most widely used devices for microencapsulation are the air-syringe pump droplet generator and the electrostatic bead generator, each of which is fitted with a single needle through which droplets of cells suspended in alginate solution are produced and cross-linked into microbeads. A major drawback in the design of these instruments is ... Webstatic bead generator, according to a three-step procedure. Briefly as shown schematically in Fig. 3, the device established electrostatic potential of 10 kV between the needle feeding the

WebMay 27, 2024 · The more recent technique to produce microparticles was an impinging aerosol technique to successfully encapsulate propranolol HCl by Hariyadi et al. and high-voltage electrostatic bead generator for BSA-alginate microparticles by Ørning et al. . WebA laborarory designed electrostatic bead generator (EBG) was used to prepare the microparticles. It contained a syr-inge pump KDS-100 and a high voltage source Glasman MK30P02.5 (Fig. 1s). Solutions of 10% bovine gelatin and 2% sodium alginate were prepared at 37°C and then sup-plemented with Na 2HPO 4 to a final content of 15% phos- tour metlife
