BSA protein writing on Si surface using the Fountain Pen Nanolithography technique. On the left is an AFM image presenting two lines of the BSA. The plot on the right shows a height line profile of these lines. A pipette of 100nm aperture has been used with contact mode of 20µm /ms writing speed.

WSxM software has been used for image processing of the pictures above: I. Horcas et al. Rev. Sci. Instrum. 78, 013705 (2007).
 

A silicon surface has been selected for writing due to its significance in the semiconductor industry. Using FPN for patterning on silicon could open the door for this technique to be integrated into different fields of semiconductors and materials.

Patterning with biological materials on silicon demonstrates the ability of FPN in biochip technology. FPN allows for patterning with biological materials onto Si surfaces, commonly used in integrated circuits and semiconductor devices.

Ideal systems for this application:

MV4000
MV2000
MV1000
