The double ratiometric fluorescence stemmed from triple response of TPE-TS@Eu\/GMP ICPs without spectral cross-interference (ME and AIE from TPE-TS and sensitized emission from Eu\/DPA) and a corresponding blue-to-red fluorescent color change, which not only benefited the direct detection of DPA with high sensitivity and selectivity, but also offered a great opportunity to realize real-time monitoring of DPA released by Bacillus subtilis spores. Furthermore, the coffee ring deposition patterns on a test paper were innovatively tuned by the quantity and morphology changes of TPE-TS@Eu\/GMP ICPs during their stimulus response toward DPA, which could be exploited as expanded signal channels. By integrating a multichannel responsive coffee ring test kit with image recognition and processing application installed on smartphones, point-of-use analysis of DPA could be realized in a low-cost and high-throughput fashion.<\/jats:p>","DOI":"10.1021\/acs.analchem.0c01570","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T06:28:21Z","timestamp":1598596101000},"page":"12934-12942","source":"Crossref","is-referenced-by-count":90,"title":["Stimulus Response of TPE-TS@Eu\/GMP ICPs: Toward Colorimetric\nSensing of an Anthrax Biomarker with Double Ratiometric Fluorescence\nand Its Coffee Ring Test Kit for Point-of-Use Application"],"prefix":"10.1021","volume":"92","author":[{"given":"Chunyu","family":"Huang","sequence":"first","affiliation":[{"name":"East China Normal University , , 500 Dongchuan Road , ,","place":["Shanghai, China, 200241"]},{"name":"Institute of Eco-Chongming , 3663 Zhongshan Road , ,","place":["Shanghai, China, 200062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruixue","family":"Ma","sequence":"additional","affiliation":[{"name":"East China Normal University , , 500 Dongchuan Road , ,","place":["Shanghai, China, 200241"]},{"name":"Institute of Eco-Chongming , 3663 Zhongshan Road , ,","place":["Shanghai, China, 200062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxin","family":"Luo","sequence":"additional","affiliation":[{"name":"East China Normal University , , 500 Dongchuan Road , ,","place":["Shanghai, China, 200241"]},{"name":"Institute of Eco-Chongming , 3663 Zhongshan Road , ,","place":["Shanghai, China, 200062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5900-2209","authenticated-orcid":true,"given":"Guoyue","family":"Shi","sequence":"additional","affiliation":[{"name":"East China Normal University , , 500 Dongchuan Road , ,","place":["Shanghai, China, 200241"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8457-4380","authenticated-orcid":true,"given":"Jingjing","family":"Deng","sequence":"additional","affiliation":[{"name":"East China Normal University , , 500 Dongchuan Road , ,","place":["Shanghai, China, 200241"]},{"name":"Institute of Eco-Chongming , 3663 Zhongshan Road , ,","place":["Shanghai, China, 200062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2414-8993","authenticated-orcid":true,"given":"Tianshu","family":"Zhou","sequence":"additional","affiliation":[{"name":"East China Normal University , , 500 Dongchuan Road , ,","place":["Shanghai, China, 200241"]},{"name":"Institute of Eco-Chongming , 3663 Zhongshan Road , ,","place":["Shanghai, China, 200062"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,8,28]]},"reference":[{"key":"2026081803322321200_cit1","doi-asserted-by":"publisher","first-page":"4484","DOI":"10.1021\/ja043623b","volume":"127","author":"Zhang","year":"2005","journal-title":"J.
