Disclosed is an additive manufacture material made from polymers and designed to be biodegradable in a landfill or oceanic environment. The material may be made of bio-based polymers made from caster beans, cellulose, corn, starch, sugarcane, etc., such as nylon 11, bio-based polyethylene, polylactic acid, polyhydroxyalkanote, polyvinyl acetate, etc., to which is added microorganism, such as a bacteria, an enzyme or other additive to facilitate/accelerate the decomposition of the polymer in an environment where the object made through AM has been disposed, e.g., discarded after useful life. The microorganism or other additives that facilitate/accelerate the decomposition of polymers can also be added to petroleum-based, non bio-based polymers.

Fouling on the surface of biomaterials and medical devices by proteins and microorganisms in the body severely hinders device functionality and drastically shortens lifetime. Currently, there is high demand for coatings that mitigate this biofouling. In this invention, the use of polyacrylamides has been explored in hydrogel coatings by building the largest library of acrylamide-based copolymer anti-biofouling hydrogels (>160 combinations) to date. A combinatorial approach was used, exploiting the ease of hydrogel synthesis to examine a high-throughput screening of platelet adhesion, precursor to thrombosis and a common culprit in biofouling. Applicability has been demonstrated of top-performing polyacrylamide-based hydrogel by (i) coating affinity-based electrochemical biosensors in vitro in a whole blood assay, and (ii) through coating an electrochemical aptamer-based device for real-time monitoring of analytes in an in vivo closed-loop system.
