A bottom-up approach was the key to the successful fabrication of this memory. This approach both minimized the number of processing steps following deposition of the molecular monolayer, as well as protected the molecules from remaining processing steps. In the following paragraphs, we briefly describe the nanofabrication procedures utilized to construct the memory circuit. A full paper describing these procedures in more detail will be submitted for publication in the near future. form an array of top Ti NW electrodes, and the crossbar structure is complete.

Finding a needle in a haystack: A new technology is demonstrated to enrich circulating tumor cells (CTCs) with high efficiency by integrating an antibody‐coated silicon nanopillar (SiNP, see picture; gray) substrate with an overlaid polydimethylsiloxane (PDMS) microfluidic chaotic mixer (turquoise). It shows significantly improved sensitivity in detecting rare CTCs from whole blood, thus providing an alternative for monitoring cancer progression.
