Application Notes 111 – Versatile Biomolecular Printing on a Variety of Surface Types

In this application note the Nano eNabler™ system is used to print proteins onto various surface types including hydrogel, nitrocellulose, and chemically treated surfaces such as silanes and self-assembling monolayers (SAMs). This demonstrates the utility of these surfaces as printing substrates for a variety of potential applications, some of which may require a flat silane or SAM surface while others may benefit from the increased loading capacity and activity retention of a 3D matrix. Observation of the printed surfaces provides information on the efficiency of protein transfer and consistency in ultramicron spot formation.
