Microfabrication approaches such as printing with micro and nanoscale resolution have dramatically changed our society through their use in diverse fields. These engineering tools are also useful for many biological applications ranging from drug delivery to DNA sequencing since they can be used to fabricate small features at a low cost and in a reproducible manner. In addition, the ability to print materials at the micro and nanoscale is potentially important for many biological and biomedical applications. Our goal is to use these techniques to better understand and manipulate cell behavior (e.g. stem cells) and to fabricate devices for high-throughput screening. This talk will describe new materials and methods developed in our lab to regulate and analyze the interaction of cells with their surroundings. To control cell migration and to restrict cell or colony size, cells and proteins were patterned using numerous printing and molding methods based on deposition of polymers. To control cell-cell contact, we have developed methods based on layer-by-layer deposition of ionic biopolymers to generate patterned co-cultures. In addition, we have developed microfluidic-based approaches to synthesize novel materials and to interface cells inside microdevices.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
