Scientists from the PennState University, Pennsylvania, have collaborated with researchers from the Cukurova University in Adana, Türkey, to mix two different polydimethylsiloxane elastomers. Using the substance combination they are able to create three-dimensional objects for organ-on-a-chip systems. This is especially interesting for smallest structures from the 3D Printer. 
 

The researchers mixed the elastomers Sylgard 184 and SE 1700 with each other and form. The small structures showed cracks and minor surface irregularities, so that cells were able to adhere to the otherwise hydrophobic surfaces.

 

The scientists have published their work in the journal ACS Biomaterials Science & Engineering:
