Video Tape Duplication by Contact Printing Method

Millimeter-scale contact printing of aqueous solutions using a stamp made out of paper and tape.

This communication describes a simple method for printing aqueous solutions with millimeter-scale patterns on a variety of substrates using an easily fabricated, paper-based microfluidic device (a paper-based "stamp") as a contact printing device. The device is made from inexpensive materials, and it is easily assembled by hand; this method is thus accessible to a wide range of laboratories and...

Non-contact tape tension measurement and correlation of lateral tape motion and tape tension transients

Non-contact tension measurement of magnetic tape is performed. Light from a focussed light source is directed at a tape surface and the light reflected from the tape is captured by a photo cell. As the tape tension varies, the divergence of the reflected light bundle changes, i.e., the amount of light seen by the photo cell is a measure for the tension in the tape. Using this noncontact tension...

Supported lipid bilayer microarrays created by non-contact printing.

Arrays of supported lipid bilayers (SLBs) provide great potential for future drug development and multiplexed biological research, but are difficult to prepare due to the sensitivity of both the lipid and protein structural arrangement to air exposure. A novel way to produce arrays of SLBs is presented based on non-contact dispensing of vesicles to a substrate through a thin surface confined wa...

Hydraulically actuated micro-contact printing engines

Micro-contact printing (μCP) is a rapid, simple and well-established method of microscale biochemical patterning. However, there is a lack of inexpensive and accessible tools for accurately controlling contact during the printing process. In this paper, controlled μCP using hydraulic actuation is demonstrated. Complete printing systems, including a substrate placed at a calibrated height above ...
