A better understanding of the phenotypic heterogeneity of protoplasts requires a comprehensive analysis of the morphological and metabolic characteristics of many individual cells. In this study, we developed a microfluidic flow cytometry with fluorescence sensor for functional characterization and phenotyping of protoplasts to allow an unbiased as...
Conference Paper
According to the urgent need for rapid detection and identification of foodborne bacteria to prevent public health event, a microfluidic electrical impedance flow cytometry assisted with convolutional neural network (ConvNet) based deep learning algorithm was proposed in this study to analyze the impedance signals of bacteria. With the assistance o...
Article
This paper reports an IC-compatible method for fabricating a PDMS-based resistive pulse sensing (RPS) device with embedded nanochannel (nanochannel-RPS) for label-free analysis of biomolecules and bionanoparticles, such as plasmid DNAs and exosomes. Here, a multilayer lithography process was proposed to fabricate the PDMS mold for the microfluidic...
Article
Despite that single-cell-type-level analyses have been extensively conducted on animal models to gain new insight into complex biological processes, the unique biological and physiological properties of plant cells have not been widely studied at single-cell resolution. In this work, an electrical impedance flow cytometry was fabricated based on mi...
Article
We have developed a new three-dimensional (3D) surface for use in biosensors that is based on modified novel thorns-like polyelectrolytes (3D-PETx), which comprises of poly-l-lysine (PLL) appended with multitude oligo (ethylene glycol) (OEG) and biotin moieties. It tethered to the sensor surface by PLL, while the OEG-biotin chains are forced to str...
Article
Primary cell wall (PCW) is a rigid yet flexible cell wall surrounding plant cells and it plays key roles in plant growth, cell differentiation, intercellular communication, water movement and defence. As a technique widely used to study the characteristics of mammalian cells, electrical impedance spectroscopy (EIS) is rarely used in plant science....
Article
In article 1900671, Qiannan Xue, Xuexin Duan, and co‐workers demonstrate a nanoscale impedimetric immunosensor based on biotin doped conductive polymer nanowire arrays which are fabricated through simple solution printing approach. This sensor can be a general platform for various bio‐analytical applications with ultrahigh sensitivity.
Article
The demand for fast and ultratrace biomarkers detection is increasing in bioanalytical chemistry. In this work, highly ordered nanowires array and sensor integration are achieved with nanoscale printing approach. Negatively charged poly(3,4‐ethylenedioxythiophene)–poly(styrenesulfonate) doped with positively charged PEGylated biotin‐derivatized pol...
Article
One-dimensional organic nanostructures are essential building blocks for high performance gas sensors. Constucting as e-nose type sensor array is the current golden standard in develping portable system for gas mixtures detection. However, facile fabrication of nanoscale sensor array is still challenging due to the high cost of the conventional nan...
Article
We report the nonlinear acoustic streaming effect and the fast manipulation of microparticles by microelectromechanical Lamb-wave resonators in a microliter droplet. The device, consisting of four Lamb-wave resonators on a silicon die, generates cylindrical traveling waves in a liquid and efficiently drives nine horizontal vortices within a 1−μl dr...

This work reported a wireless controlled micro-actuator system for rapid heating and mixing of multiple droplets using integrated arrays of micro-fabricated 2.5 GHz solid-mounted thin-film piezoelectric resonators (SMRs) and a millimeter-scale omnidirectional antenna. An equivalent circuit is proposed to analyze the mechanism of the heating, mixing...
Article
This paper reports a surface functionalization strategy for protein detections based on biotin-derivatized poly(L-lysine)-grafted oligo-ethylene glycol (PLL-g-OEGx-Biotin) copolymers. Such strategy can be used to attach the biomolecule receptors in a reproducible way simply by incubation of the transducer element in a solution containing such copol...
Article
A new surface functionalization scheme for nano-Bio field effect transistors (FETs) using biocompatible polyelectrolyte thin films (PET) is developed. PET assemblies on Si nanowires (Si-NWs) are driven by electrostatic interactions between the positively charged polymer backbone and negatively charged Si/SiO2 surface. Such assemblies can be directl...
