Evaporation‐Enhanced Redox Cycling for Rapid Detection of Attomolar SARS‐CoV‐2 Virions Using Nanolithography‐Free Electrochemical Devices

Advanced Materials Technologies, EarlyView.
This study presents microfabricated electrochemical sensors for detecting ultralow viral particles counts through evaporation‐enhanced redox cycling (E2RC). To achieve sub‐micrometer gap in interdigitated microelectrodes, a scalable, nanolithography‐free fabrication method is developed.

Research on the influence of stamping materials on resist flow and the residual layer in thermal nanoimprint lithography

Micro & Nano Letters, 2023
Various stamp materials can significantly affect the filling quality of nanoimprint lithography (NIL). The effects of different stamp materials on the imprinting process were investigated from the angles of residual layer (RL) thickness, contact pressure,

Application of helium ion microscopy to nanostructured polymer materials

Nanotechnology Reviews, 2014
Helium ion microscopy (HIM) is a relatively new high-resolution nanotechnology imaging and nanofabrication tool. HIM offers a near-molecular resolution (approaching that of TEM) combined with a simplicity of sample preparation and high depth of field ...

Outermost Cationic Surface Charge of Layer‐by‐Layer Films Prevents Endothelial Cells Migration for Cell Compartmentalization in Three‐Dimensional Tissues

Advanced Science, EarlyView.
A nanometer‐sized artificial basement membrane (A‐BM) is developed to replicate the barrier functions of the basement membrane and prevent cell migration. It is demonstrated that the outermost cationic surface charge of nanofilms can effectively inhibit endothelial cell migration and sprouting, allowing for the construction of 3D patterned vascular ...

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

Advanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

Atomistic mechanisms for frictional energy dissipation during continuous sliding

Scientific Reports, 2021
After more than a century of detailed investigations into sliding friction, we have not arrived yet at a basic understanding of energy dissipation, even for the simple geometry of a rigid slider moving over a perfectly periodic counter surface.

Diffusion modeling for Dip-pen Nanolithography [PDF]

arXiv, 2018
The diffusion model for the dip pen nanolithography is similar to spreading an ink drop on a paper. Nanolithography uses Atomic Probe Microscope like probes to deliver the ink drop on to the substrate. The model considers the ink to be molecular. Some models have been developed considering fluid ink, some with thiol inks, particulate inks and polymer ...

Ohmic Response in BiFeO3 Domain Walls by Submicron‐Scale Four‐Point Probe Resistance Measurements

Advanced Electronic Materials, EarlyView.
Lateral transport measurements of multiferroic domain walls (DWs) in BiFeO3 thin films employing a novel, lithography‐free method are presented. Using a submicron‐scale multi‐point probe (MPP), ohmic DW conduction behavior is demonstrated, including the first collinear, four‐point resistivity value of a single DW, free of contact resistances.
