Journal ArticleDOI
Material transport in dip-pen nanolithography
TL;DR: A detailed review of the literature can be found in this article, where the authors classify inks into three general categories based on their transport properties and highlight the myriad ways that DPN can be used to perform chemistry at the tip of a scanning probe.
Journal ArticleDOI
High-Throughput, Algorithmic Determination of Nanoparticle Structure from Electron Microscopy Images
TL;DR: A computational method to algorithmically analyze EM images that allows for the first automated structural quantification of heterogeneous nanostructure populations, with species that differ in both size and shape is reported.
Journal ArticleDOI
Importance of the DNA “bond” in programmable nanoparticle crystallization
Robert J. Macfarlane,Ryan V. Thaner,Keith A. Brown,Jian Zhang,Byeongdu Lee,SonBinh T. Nguyen,Chad A. Mirkin +6 more
TL;DR: This work observed the reorganization of nanoparticle superlattices using time-resolved synchrotron small-angle X-ray scattering in systems with different DNA sequences, salt concentrations, and densities of DNA linkers on the surface of the nanoparticles.
Journal ArticleDOI
The role of viscosity on polymer ink transport in dip-pen nanolithography.
Guoliang Liu,Yu Zhou,Resham J. Banga,Radha Boya,Keith A. Brown,Anthony J. Chipre,SonBinh T. Nguyen,Chad A. Mirkin +7 more
TL;DR: This study investigates the transport of block copolymer inks with varying viscosities, from an atomic force microscope (AFM) tip to a substrate, and proposes a mass transfer model to describe this behaviour.
Journal ArticleDOI
Apertureless Cantilever‐Free Pen Arrays for Scanning Photochemical Printing
Yu Zhou,Zhuang Xie,Zhuang Xie,Keith A. Brown,Daniel J. Park,Xiaozhu Zhou,Peng-Cheng Chen,Michael Hirtz,Qing Yuan Lin,Vinayak P. Dravid,George C. Schatz,Zijian Zheng,Chad A. Mirkin +12 more
TL;DR: A novel, apertureless, cantilever-free pen array can be used for dual scanning photochemical and molecular printing and Serial writing with light is enabled by combining self-focusing pyramidal pens with an opaque backing between pens.
