Screen printing technology provides a cheap and easy means to fabricate disposable electrochemical devices in bulk quantities which are used for rapid, low-cost, on-site, real-time and recurrent industrial, pharmaceutical or environmental analyses. Recent developments in micro-fabrication and nano-characterization made it possible to screen print reproducible feature on materials including plastics, ceramics and metals. The processed features forms screen-printed disposable biochip (SPDB) upon the application of suitable bio-chemical recognition receptors following appropriate methods. Adequacy of biological and non-biological materials is the key to successful biochip development. We can further improve recognition ability of SPDBs by adopting new screen printed electrode (SPE) configurations. This review covers screen-printing theory with special emphasis on the technical impacts of SPE architectures, surface treatments, operational stability and signal sensitivity. The application of SPE in different areas has also been summarized. The article aims to highlight the state-of-the-art of SPDB at the laboratory scale to enable us in envisaging the deployment of emerging SPDB technology on the commercial scale.
丝网印刷技术提供了一种廉价且简便的方法,可大量制造一次性电化学装置,这些装置用于快速、低成本、现场、实时以及重复性的工业、制药或环境分析。微制造和纳米表征方面的最新进展使得在包括塑料、陶瓷和金属在内的材料上丝网印刷可重复的特征成为可能。经过处理的特征在采用适当方法施加合适的生化识别受体后形成丝网印刷一次性生物芯片(SPDB)。生物和非生物材料的适用性是生物芯片成功开发的关键。我们可以通过采用新的丝网印刷电极(SPE)配置来进一步提高SPDB的识别能力。本综述涵盖丝网印刷理论,特别强调SPE结构、表面处理、操作稳定性和信号灵敏度的技术影响。还总结了SPE在不同领域的应用。本文旨在突出实验室规模下SPDB的最新技术水平,以便我们能够设想新兴的SPDB技术在商业规模上的应用。
