Title: “Electrochemical sensors based on wearable carbon textiles”
Abstract: Wearable sensors have attracted considerable interest owing to their tremendous promise for applications in various fields, such as clinical diagnosis, environmental pollution monitoring and food quality assessment, due to their practical advantages of operation convenience, low cost and in situ analysis mode. Among different sensing methods, electrochemical sensing is very popular due to its high efficiency and accuracy. Sensing materials are essential for the detection of analytes.
Based on the sensing materials, there are two kinds of electrochemical biosensors, enzymatic and non-enzymatic sensors. Compared with enzymatic sensors, non-enzymatic sensors show enhanced stability, simplicity, reproducibility, and cost effectiveness. Among a variety of electrode materials, carbon textile is flexible, conductive and stable in corrosive conditions. Furthermore, it provides large surface area, high porosity and a three dimensional structure, which are crucial for nanostructure-based electrochemical devices. It is also inexpensive and biocompatible among carbon-based materials. However, proper surface functionalization is needed to achieve good selectivity for the detection of specific analytes. Herein, we are developing wearable non-enzymatic electrochemical sensors for the detection of different biomarkers in human fluid.
Title: “Scalable Synthesis of Core-Vest Nanoparticles Assisted by Surface Plasmons”
Abstract: Compared with single-component nanocrystals, core-shell nanocrystals show better performance in various areas, such as energy harvesting and storage, catalysis, sensing and functionalized targeted cell therapy. The solution-based fabrication process is the most common strategy for synthesizing core-shell structures. However, the complex and difficult-to-scale fabrication procedures severely reduce their practical applications. Besides, the thermodynamically driven process of the fabrication of core-shell nanostructures possesses several constraints on their size and geometry, the most prominent being the high degree of uniformity in their shape. If energy (or matter) could be channeled with super-resolution, more complex architectures would become possible, such as partial cladding of complex nanoparticles with nontrivial shapes.
In this project, we exploit the plasmonic activity of the nanoparticle itself to help channel light into a nonuniform heatmap over the particle with sub-particle resolution. We show that surface plasmons which result from the coupling of light with the free electrons in a metal, can be harnessed to achieve a variety of pre-programmed designer core- shell nanostructures. By localizing the energy carried by far-field radiation onto nanometer-sized regions, surface plasmon effectively create hot blueprints that drive self- assembly of composite structures. Herein, several kinds of core-shell nanostructures are fabricated assisted by surface plasmon to illustrate the concept, and several possible applications of these complex nanomaterials are discussed.
