|Title:||Amplification of interference color by using liquid crystal for protein detection||Authors:||Zhu, Q.
|Issue Date:||9-Dec-2013||Citation:||Zhu, Q., Yang, K.-L. (2013-12-09). Amplification of interference color by using liquid crystal for protein detection. Applied Physics Letters 103 (24) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.4844835||Abstract:||Micrometer-sized, periodic protein lines printed on a solid surface cause interference color which is invisible to the naked eye. However, the interference color can be amplified by using a thin layer of liquid crystal (LC) covered on the surface to form a phase diffraction grating. Strong interference color can thus be observed under ambient light. By using the LC-amplified interference color, we demonstrate naked-eye detection of a model protein - immunoglobulin G (IgG). Limit of detection can reach 20 μg/ml of IgG without using any instrumentation. This detection method is potentially useful for the development of low-cost and portable biosensors. © 2013 AIP Publishing LLC.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/88521||ISSN:||00036951||DOI:||10.1063/1.4844835|
