Abstract Soft robotics is one of the new strategies in the field of medical treatment and pharmaceutical. Soft robotic can be applied for diagnosis tool and drug delivery to the specific tissue target. Soft robotic can be made using bio-3D printers using nano-composite as bio-ink which have a critical influence in properties and structure formed of the printed object. Therefore, it is able to maintain its shape and expected have good biocompatibility. Poly(N-isopropyl acrylamide) or PNIPAAm has the ability as photo-actuator due to its temperature-sensitive properties. PNIPAAm can shrinks in above of lower critical temperature (LCST). The surface plasmon resonance (SPR) of a metal nanoparticle can be used as light into heat transfer initiator. The irradiation of light in the same wavelength with its SPR can initiate the light into heat transfer phenomena. Thus, PNIPAAm and metal nanoparticle properties to be employed as nano-composite bio-ink that has a potential for soft robotic photoresponsive material. In this study, the printability and mechanical properties of nano-composite bio-ink are evaluated through rheology and elasticity measurement by Young modulus test. Instead of those properties, the challenge of this study is to find out the best crosslinking agent by which the bio-ink has good elasticity and mechanical properties of the printed product. Furthermore, nano-composite bio-ink generated in this study high reproducibility, good properties and biocompatible.
