Title: | Self-assembly of cholesterol DNA at liquid crystal/aqueous interface and its application for DNA detection | Authors: | Lai, S.L. Hartono, D. Yang, K.-L. |
Issue Date: | 2009 | Citation: | Lai, S.L., Hartono, D., Yang, K.-L. (2009). Self-assembly of cholesterol DNA at liquid crystal/aqueous interface and its application for DNA detection. Applied Physics Letters 95 (15) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3247895 | Abstract: | In this letter, we report a strategy of detecting the DNA targets by using a thin layer of self-assembled cholesterol-labeled DNA probes at the liquid crystal (LC)/aqueous interface. When the system is exposed to 51 μg/ml of complementary DNA targets, the optical appearance of LC shows a continuous change from dark to bright under the crossed polars within 15 min. No obvious change can be observed when the system is exposed to one or two base-pair mismatch DNA targets. This system provides a principle for label-free and real-time detection of DNA targets without any fluorescent labeling. © 2009 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/64566 | ISSN: | 00036951 | DOI: | 10.1063/1.3247895 |
