"287_63" refers to a specific chemical identifier—specifically —used in groundbreaking research on modified alginate polymers to prevent the foreign body response (fibrosis) in medical implants. Research Context

: Highly cited papers in Nature Medicine and Nature Biotechnology (circa 2016) by the Anderson and Langer labs.

: It is a triazole-based modification of alginate, specifically created through "click chemistry" to change the surface properties of the polymer.

: In animal models, 287_63 was identified as one of the top-performing "anti-fibrotic" materials. It significantly reduced the formation of scar tissue around implants.
