1 Table-top system for LIFT: Protoprinter.

2 Protein microarray produced by LIFT.

Task

Biomedical engineering applications, used to manufacture

microarrays or in vitro assays, involve the transfer of valuable,

high-viscous or solid materials. State of the art processes such

as inkjet printing cannot handle these materials satisfactory. In

particular, a transfer of high viscous materials in small volumes

(picoliter) or solid materials is challenging. Thus a new techno-

logy, that allows the handling of these materials, is needed.

Method

A pulsed laser source is used to evaporate a sacrificial absorp-

tion layer, thereby transferring a material from a transfer slide

to a receiver surface. This enables the transfer of high-viscous

and solid materials without damage, achieving a spot size of

down to 10 μm and with minimal material loss. Even sensitive

objects such as cells can be accurately positioned on any given

surface. A commercially available plotter is adapted for this

purpose.

Performance Data

• Three-axis positioning system based

on the GeSiM Nano-Plotter NP 2.1

• Microchip Laser (355 nm)

• Laser scanning module, 70 mm x 70 mm field of view

• Resolution X/Y: 2 μm, Z: 10 μm

• Working area X/Y/Z: 200 x 165 x 40 mm

• Transferable materials: biopolymers (e. g. collagen,

alginate, BD MatrigelTM, etc.), living cells

Result

In collaboration with GeSiM GmbH, a scanner and a minia-

turized solid-state laser were added to a compact positioning

system, the Protoprinter. This setup supports end-to-end

processing of carriers for transfer materials. The donor film

and the substrate to be coated can be positioned relative to

one another, thus allowing free formed pattern to be printed.

Applications

The developed table-top Protoprinter system for high-viscous

and solid materials supports rapid transfer of proteins and

DNA or it can be used in the manufacture of analytical

microarrays or in vitro assays. The portable setup allows a

production in standard environmental conditions. Flexible

component holder and interchangeable material carriers

also pave the way for transferring solid materials and new

formulations of bioactive materials onto medical engineering

components. Consequently the LIFT process also adds up to an

economic solution for small-scale applications.
