Controlled cell adhesion on microstrucured Polydimethylsiloxane (PDMS) surface using femtosecond laser

We demonstrate controlled cell adhesion on Polydimethylsiloxane (PDMS) substrate microstrucured by a femtosecond laser. The effect of micro structures on cell attachment, alignment, patterned growth and cells proliferation were investigated over 24hrs, 48hrs and 72hrs.
