Abstract: A deterministic lateral displacement array that includes a channel, within a substrate, having a first sidewall, a second sidewall, and a channel length. A condenser portion that includes an entry port and an exit port. A first array of pillars is disposed between the entry port and the exit port of the condenser portion along the channel length, the first array of pillars operative to drive a first material particle and a second material particle towards the first sidewall of the channel. A separator portion that includes an entry port and an exit port, and a second array of pillars disposed between the entry port and the exit port of the separator portion along the channel length, the pillars operative to drive the first material particle towards the second sidewall of the channel.

Abstract: The present disclosure relates to methods for forming an antimicrobial nanostructure and antimicrobial articles. The methods may include: providing a master template of a layout of the antimicrobial nanostructure on a silicon substrate, depositing a silicon nitride layer on a top surface of the silicon substrate, forming a patterned lithographic resist mask layer on a top surface of the silicon nitride layer, generating certain silicon pillars according to the patterned lithographic resist mask using a resist and reactive ion etching, forming certain lateral silicon nanospikes on the silicon pillars by performing metal assisted chemical etching (MacEtch), and removing the silicon nitride layer and bonding a top cover glass on the silicon pillars to form the antimicrobial nanostructure having lateral silicon nanospikes. The antimicrobial article may include a component of an electronic device, a biomedical article, a household product, a food grade article, a transportation component, or a public building component.

Abstract: Described herein are microfluidic devices and methods of detecting an analyte in a sample that includes flowing the sample though a microfluidic device, wherein the presence of the analyte is detected directly from the microfluidic device without the use of an external detector at an outlet of the microfluidic device. In a more specific aspect, detection is performed by incorporating functional nanopillars, such as detector nanopillars and/or light source nanopillars, into a microchannel of a microfluidic device.
