Dip-pen nanolithography (DPN) is a nanowriting procedure that employs an AFM tip as a “nanopen” to deposit organic molecules onto a substrate surface. This paper describes the application of DPN to ...

A new study introduces a self-powered smart pen that analyzes handwriting in real time to detect early signs of Parkinson’s ...

No cleanroom, no photomask—just precision optics and photoresist. This DIY method brings semiconductor-scale patterning into reach for makers and researchers alike.

We present a novel method for the geometric calibration of micro-lens-based light field cameras. Accurate geometric calibration is the basis of various applications. Instead of using sub-aperture ...
