On-Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography. [PDF]

Small Methods
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.
