Combinatorial Biomolecular Nanopatterning for High-Throughput Screening of Stem-Cell Behavior.

: A novel combinatorial biomolecular nanopatterning method is reported, in which multiple biomolecular ligands can be patterned in multiple nanoscale dimensions on a single surface. The applicability of the combinatorial platform toward cell-biology applications is demonstrated by screening the adhesion behavior of a population of human dental pulp stem cell (hDPSC) on 64 combinations of nanopatterned extracellular matrix (ECM) proteins in parallel.
