Dual beam laser transfer

A method of transferring a biological, polymer or monomer material coated on a front surface of donor substrate to a front surface of a receiver substrate, the front surface of the donor substrate facing the front surface of the receiver substrate, the donor substrate comprising a transparent portion and an absorbing layer on a front side of the transparent portion, the method comprising:

• irradiating with a first laser beam of a laser a portion of a back side of the transparent portion to increase the pressure and/or temperature of the absorbing layer to eject a portion of the biological, polymer or monomer material from the donor substrate and transfer the portion of the biological, polymer or monomer material to the receiver surface;
• post-processing the portion of the biological, polymer or monomer material transferred on the receiver substrate by irradiating with a second laser beam of a laser a portion of the front side of the receiver surface, wherein in case of transferring polymer or monomer material, the post-processing comprises photo-polymerization of the transferred polymer or monomer material;
• and wherein in case of transferring biological material, the post-processing comprises functionalizing the transferred biological material, wherein a laser energy for the post-processing is at a level that does not induce any damages to the biological, polymer or monomer material, further comprising setting a fluence of the second laser beam at between 30 and 500 mJ/cm2.
