FORMULASI DAN KARAKTERISASI MEMBRAN HIDROGEL BERPORI BERBASIS ETIL SELULOSA DAN GELATIN DENGAN METODE ICE PARTICLE LEACHING SEBAGAI PERANCAH DALAM PENGEMBANGAN REKAYASA JARINGAN LUNAK
Abstract
Tissues and organs had many functions for every mechanisms in the body. If its get damaged, body will automatically restore it. However body’s recovery has its limit, especially with mild or severe damage in tissues and organs. Because of its important function, recovery of the damaged tissues and organs need be done as soon as possible. Recovery can be done with standard treatment, using drugs or pharmacological treatment. Tissue engineering therapy could became an alternative if standard treatment fails. The aims of tissue engineering is stimulate body to form new tissue at the damaged area and carried out by providing the right materials to trigger the cells to regenerate.
Porous hydrogel membranes producted using ice particle leaching method. Hydrogel formulation of porous membrane was conducted by varying the composition of ethyl cellulose and gelatin i.e F1 (1: 1), F2 (1: 1.5) and F3 (1: 2). Yields analysis will be conducted using physics characteristic such as organoleptic test, percent of age swelling, weight loss, UTS (Ultimate Tensile Strength) and the description of porous hydrogel membrane using SEM (Scanning Electron Microscope).
The results showed that the combination of ethyl cellulose and gelatin can be formulated into a porous hydrogel membranes with ice particle leaching method. Organoleptic test has the highest fineness in F3, and the most elastic in F1. Percentage of swelling age with highest value in the F1 is 23.73 ± 9.20%. The smallest values of weight loss at t=15 minutes found the F2 is 0.45 ± 0.01% and at t=30 minutes the smallest value found in F1 is 0.82 ± 0.05%. UTS in F1 has the smallest value i.e 0,8967 MPa. The result of the examination using SEM at F2 showed pores with a size of 2,830 μm at a magnification of 3.000 times. The physical-mechanical characteristics of the hydrogel membrane needs to be improved for the purpose of tissue engineering applications
