13.1 Introduction
Laser.direct-write.is.a.material.processing.technique.that.allows.for.mesoscopic-scale.pat-
terning.with.a.wide.variety.of.materials..This.review.presents.research.on.the.mechanism.
of.the.transfer.process,.focusing.on.AFA-LIFT.and.MAPLE.DW..A.variety.of.examples.of.
biomaterial.transfers.will.then.be.described..Building.off.of.this,.perspectives.for.future.
utility.of.laser.direct-write.are.suggested.
Laser.direct-writing.allows.for.the.localized.deposition.of.material.transferred.from.the.
ribbon—see.Figure.13.1..There.are.several.varieties.of.laser.direct-write.that.have.been.used.
with.materials.ranging.from.metals.and.ceramics.for.electronic.applications.to.cells.and.
