“…Water pollution threatens human health and the environment and hence the rapid determination of contaminants is extremely important (Long et al 2013;Guo et al 2012). There is an increasing demand for developing a fast, convenient, and reliable analytical methodology with easy-to-operate devices for on-site analysis in order to determine contaminants in the field (Barrek et al 2009;Gu, Wang, and Yan 2010).…”

This paper describes the development of a portable microfluidic chip based on a surface-enhanced Raman spectroscopy (SERS) sensor for crystal violet analysis. A Y-shape microfluidic chip with a staggered herringbone structure was designed to efficiently mix the analyte and SERS active silver colloid. The subsequent detection of the analyte was performed on the microfluidic chip by a portable Raman system. Compared with other methods, this sensor is easy to operate and is expected to have applications for rapid and sensitive on-site analysis. A good linear correlation over the concentration range of 10 to 750 nM of crystal violet with a correlation coefficient of 0.992 was obtained. The recovery was between 98.6% and 102.9% for crystal violet in river water with relative standard deviations between 2.43% and 4.26%.

“…p-tert-Butylcalix[4]-aza-crown 4 was refluxed with 3,4,9,10-perylenetetracarboxylic dianhydride 1 in DMF to give PB-CX [4] in 80% yield. PB-CX [4] was characterized by a combination of FTIR, 1 H NMR, 13 C NMR and APT, COSY NMR, and elemental analysis (Supplementary data). The 1 H NMR spectra of PB-CX [4] and 4 was depicted in Fig.…”

“…In the middle of the most toxic metals, mercury is the one widespread in air, water, and soil, generated by sources like gold productions, coal plants, thermometers, barometers, caustic soda and mercury lamps [3][4][5][6][7][8][9]. Mercury contaminations can induce strong damage to the central nervous system, and its accumulations in the human body may lead to various cognitive, motor disorders and Minamata disease [10][11][12][13]. On October 10, 2013, more than 90 countries in the world signed "The Minamata Convention on Mercury", a new global treaty to cut mercury emissions and releases and set up controls on products, mines and industrial plants [14].…”

“…Впровадження на ринок тест-систем другої групи стримує складність створення серійної форми їх продукції, що обумовлено в першу чергу невизначеністю ринку збуту тест-систем. Од-ним із шляхів впровадження даних тест-систем може стати ринок ЕЛЗ, адже вони мають ряд переваг порі-вняно із тест-системами масового виробництва: но-ваторство підходів і рішень, широке використання нових матеріалів та технологій іммпегрування, засто-сування нових та удосконалення існуючих реагентів [7,10,12,13].…”
