In a report published by MedMarket Diligence LLC in 2017, the United States accounts for 30% of the 114 million surgical wounds that occur every year worldwide. The traditional method of closing surgical incisions are staples and sutures. The major disadvantages of staples and sutures are pain, infection, and added trips to doctor to remove them. Medical professionals have an increasing interest in ways to decrease the risk of infection and eliminate the damage of healthy tissue near the surgical site. Surgical sealants are a promising technology that could hold incisions closed without mechanical support of sutures or staples. There are a few commercially available surgical sealants. Commercially available surgical sealants have poor elasticity and adhesive strength and, therefore, require mechanical support. A strong and elastic surgical sealant would not require additional support. A first generation sealant have addressed the elasticity problem with the development of their first generation surgical sealant.

Recently, researchers at Purdue University have modified their their first generation surgical sealant to improve its adhesive strength. The adhesive strength was higher for the second generation in comparison to the first generation surgical sealant on pig skin at physiological conditions. The adhesive strength was also measured on aluminum and it was found that second generation was 130% stronger than first generation adhesive and 14,000% stronger than Tisseel (commercially available surgical sealant from Baxter).

-Decreased risk of incision infection
-Decreased pain and scarring at surgical sites
-High adhesive strength and elasticity

Potential Applications:
-Closing surgical incisions
