摘要： 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.

摘要： Aspects include a method of manufacturing a flexible electronic structure that includes a metal or doped silicon substrate. Aspects include depositing an insulating layer on a silicon substrate. Aspects also include patterning a metal on a silicon substrate. Aspects also include selectively masking the structure to expose the metal and a portion of the silicon substrate. Aspects also include depositing a conductive layer including a conductive metal on the structure. Aspects also include plating the conductive material on the structure. Aspects also include spalling the structure.

摘要： 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.

摘要： 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.

摘要： The method comprises contacting a silicon substrate with a silver salt and an acid for a time effective to produce spikes having a first end disposed on the silicon substrate and a second end extending away from the silicon substrate. The spikes have a second end diameter of about 10 nm to about 200 nm, a height of about 100 nm to 10 micrometers, and a density of about 10 to 100 per square microns. The nanostructures provide antimicrobial properties and can be transferred to the surface of various materials such as polymers.
