Engineered heart tissue chips are drug-screening chips designed based on engineered heart tissue (EHT). This method involves embedding cardiac cells from different species, including rodents and humans, into a fibrin gel containing polydimethylsiloxane (PDMS) to enhance elasticity. After a simple two-week casting and culture process, EHTs with three-dimensional structures and mechanical responsiveness can be generated. The chips are specifically tailored for 24-well plates. Post Dimensions: length 10 mm, diameter 1 mm, spacing 8.5 mm. Compatible for use with the 4-chamber holder.
