Synthesis and physical properties of chitosan/alginate/silver nanoparticles hydrogel scaffolds

A biodegradable scaffold in tissue engineering serves as a temporary skeleton to accommodate and stimulate new tissue growth. Alginate (Alg) and chitosan (Chi) are both popular materials applied as biomaterials or bioimplants. However, Alg derived from brown algae is highly compliant and easily deco...

description A biodegradable scaffold in tissue engineering serves as a temporary skeleton to accommodate and stimulate new tissue growth. Alginate (Alg) and chitosan (Chi) are both popular materials applied as biomaterials or bioimplants. However, Alg derived from brown algae is highly compliant and easily decomposed in fluid, whilst Chi derived from shrimp shells has weak strength. In rectify these problems, the development of Chi and Alg based biodegradable scaffolds incorporated with silver nanoparticles (AgNPs) with enhanced mechanical properties and biosafe function is proposed. Different ratios of chitosan/alginate (Chi/Alg) were prepared and the effect of different ratio (1:1, 1:2 and 2:1) to the mechanical with and without AgNPs were investigated. Meanwhile, swelling/degradation test and dynamic mechanical analysis (DMA) were conducted to study the properties of Chi/Alg based scaffold. Swelling/degradation test and DMA show that Chi/Alg and chitosan/alginate/silver (Chi/Alg/AgNPs) nanoparticles has adequate swelling and compressive modulus that exceed the epidermis’ Young modulus, thus able to provide mechanical support upon application. As a result, the incorporation of chitosan in the Alg and AgNPs improved physical and mechanical properties of hydrogel itself and provide biosafe environment during the study. Keywords: bio-composite, silver nanoparticles, alginate, chitosan, hydrogel, mechanical properties
