There are two key parameters during the preparation process, the fiber cone angle and the density of decorated AgNPs on the fiber tip surface. Their theoretical analysis on the forming mechanism and the optimization process is studied in detail. The tapered fibers with angles from 0.5 to 30\u00b0 are successfully prepared, with a chemical method in a small tube using a bending interface. AgNPs with different densities are decorated on the surface of the tapered fibers with an electrostatic adsorption method. The optimized tapered fiber SERS probe with an angle of 12\u00b0 and AgNPs density of 26.67% provides the detection of Rhodamine 6G (R6G) with 10\u221210 mol\/L.<\/jats:p>","DOI":"10.3390\/s21072300","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T21:09:45Z","timestamp":1616706585000},"page":"2300","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Optimized Tapered Fiber Decorated by Ag Nanoparticles for Raman Measurement with High Sensitivity"],"prefix":"10.3390","volume":"21","author":[{"given":"Tao","family":"Li","sequence":"first","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology &amp; System (Ministry of Education), Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhinan","family":"Yu","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology &amp; System (Ministry of Education), Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhengkun","family":"Wang","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology &amp; System (Ministry of Education), Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Zhu","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology &amp; System (Ministry of Education), Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Key Laboratory of Optoelectronic Technology &amp; System (Ministry of Education), Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1088\/0957-0233\/12\/5\/704","article-title":"Raman spectroscopy for chemical analysis","volume":"12","author":"McCreery","year":"2001","journal-title":"Meas.
