“…However, the values of q for 18/2 PVA/sericin gels from both species were statistically higher than that of the pure PVA gels. Previous studies have reported that incorporation of ionic biological polymers such as heparin and chondroitin sulfate into PVA hydrogels has increased the swelling capacity,1, 3, 50 and this study also demonstrates a trend towards increased swelling with the incorporation of sericin. Sericin proteins have been reported to be negatively charged at neutral pH,26, 50 and therefore it would be expected that the more negatively charged chains that are incorporated the more the swelling will increase.…”

Sericin peptides and PVA are chemically modified with methacrylate groups to produce a covalent PVA/sericin hydrogel. Preservation of the sericin bioactivity following methacrylation is confirmed, and PVA/sericin hydrogels are fabricated for both B. mori and A. mylitta sericin. Cell adhesion studies confirm the preservation of sericin bioactivity post incorporation in PVA gels. PVA/A. mylitta gels are observed to facilitate cell adhesion to a significantly greater degree than PVA/B. mori gels. Overall, the incorporation of sericin does not alter the physical properties of the PVA hydrogels but does result in significantly improved cellular interaction, particularly from A. mylitta gels.

Sericin is a globular protein that represents 20% to 30% of the silk fiber from Bombyx mori silkworm cocoon. This protein is usually removed from the raw fiber and discarded by silk producers, a process known as degumming. However, sericin possesses significant biological properties that allows its application in various fields. The antioxidant activity is one of its most relevant benefits. Several authors have reported its anti-tyrosinase activity, lipid peroxidation inhibition and free radical neutralization. The antioxidant potential of sericin protein varies according to the extraction method used. Even though a wide variety of extraction techniques have been studied, simple technics including water at high temperature have exhibited efficient results. Furthermore, this method does not interfere with the safety of sericin for subsequent applications in food.

“…These properties allow wide-spread use of sericin in medical, cosmetics and food industry (Kundu, Dash, Dash, & Kaplan, 2008). Sericin can be cross-linked, copolymerized or blended with other polymers to produce new biodegradable materials with improved properties (Capar, Aygun, & Gecit, 2009). Fabrics treated with sericin have been reported to prevent abrasive skin injuries and development of rashes in products such as diapers, diaper liners and wound dressings (Zhang, 2002).…”

Sericin, a silk protein, has high potential for use in biomedical applications. It has important attributes such as excellent oxygen permeability, cell protecting and antioxidant action, moisture regulating ability, protection from ultraviolet (UV) radiation and microbes, wound healing, anticancer and anticoagulant properties. Sericin, however, has no direct affinity for textiles. In this study conditions for imparting a durable finish to polyester, based on sericin have been optimized. Ten grams per litre of sericin concentration with 10 mL/L of glutaraldehyde cured at 130°C for 2 min was found to give best application. Sericin content in finished samples was estimated by measuring the colour value of treated fabrics dyed with Methylene Blue. SEM analysis showed creation of nano-roughness on the surface of polyester after exposure to UV light and smoothening of fabric surface after application of sericin. Treated samples showed enhanced vertical wicking and moisture regain. They also exhibited improved antistat, ultraviolet protection and radical scavenging activity. These properties make sericin-treated fabrics suitable for use as medical textiles in wound dressings and for healing abrasive skin injuries in patients suffering from atopic dermatitis, pressure ulcers and rashes.
