Computation-assisted nanopore detection of uranyl ions

Roozbahani G.M, Chen X., Zhang Y., Guan X., Illinois Institute of Technology, US

Because of uranium mining, nuclear power production, nuclear weapon development, as well as other industrial and medical application, uranium has been one of the most common radioactive contaminants in the environment, which raises concerns about [...]

Design and Simulation of Electrostatic Imaging System based on MEMS

Li M-X, Chen X., Pan X., Kang J-S., Beijing Institute Technology, CN

The electrostatic imaging system obtains the contour profile of charged target by sensing the electrostatic field around. MEMS technology has the characteristic of microelectronic integration and miniaturization. In this paper, an electrostatic imaging system is [...]

nano Droplet Array Plates (nDAPs): 3D Cell Culture in Anchored Hydrogel Droplets Compatible with Conventional Microplates

Xu Q.F., Chen X., Lyons A.M., ARL Designs LLC, US

University researchers as well as large pharmaceutical companies need improved technologies for discovering new drugs. Current drug-discovery approaches are highly inefficient, as

Research on human-computer interaction technology based on electrical detection technology

Han H-P., Tang K., Lang X-Q., Chen X., Beijing Institute Technology, CN

Human-computer interaction (HCI) technology has emerged as a crucial dimension of computer science and information industry. HCI with keyboard and mouse has started to lose ground, as people tend to harness the power of body [...]

Magnetically Aligned Nanotubes in Nanocomposite Membranes for High-Performance Filtration Applications

Ignacio-de Leon P., Chen X., Rabe E., Urgun-Demirtas M., Puga M., Zhou Z., Brotzman R., Argonne National Laboratory, US

Nanocomposite membranes, with magnetic nanotubes embedded in polyethersulfone (PES) membrane to form a permselective layer on microporous supports, are reported in this study for potential applications in wastewater treatment. Two new processes, alignment of nanotubes [...]

Rapid prototyping bacterial spore hygro-actuators for soft robotics and adaptive materials

Cavusoglu A.‐H., Chen X., Tatem K., Sahin O., Columbia University, US

Over the past decade, rapid prototyping has migrated from the research and industrial labs into the homes of consumers. However, these solid models are limited in demonstrating dynamic actuation. A large range of soft materials [...]

Potential of Water‐Responsive Materials to Harvest Energy from Evaporation

Cavusoglu A.‐H., Chen X., Sahin O., Columbia University, US

Water-responsive materials swell and shrink in response to changes in relative humidity (RH) and can be potentially used to harvest energy from evaporating water. Here, we investigated the potential of harvesting energy from naturally evaporating [...]

Epidermal Growth Factor-Ferritin H-Chain Nanoparticles as Nanocarrier of

Huang Y., Chen X., Cao X., East China University of Science and Technology, CN

The emergence of drug-resistant cancer cells together with the toxicity side effect of chemotherapy agents are the major obstacle in cancer treatment. We focused on providing a new pattern of protein-based nanoparticle as drug delivery [...]

Free-Surface Microfluidics: Exploring New Actuation and Sensing Methods

Yu G., Lei N., Chen X., Xue W., Xu J., Xue W., Washington State University, US

Unlike traditional microchannel-based microfluidics, free-surface microfluidics features no channel, ease to clean, simple design fabrication and operation, as well as external access to the samples. It has been proven that free-surface droplets can be actuated [...]

Microfluidic manipulation of Caenorhabditis elegans using acoustic radiation forces

Yu G., Chen X., Xu J., Washington State University, US

The ability to precisely trap, transport and manipulate micrometer-sized objects is very important in microfluidic applications. Caenorhabditis elegans (C. elegans) is one of the most commonly used animals in biological and medical research due to [...]
