Surface Enhanced Raman Spectroscopy (SERS) has traditionally relied on noble metals such as gold and silver for strong electromagnetic enhancement. However, these substrates present challenges in terms of cost, stability, and integration into real-world applications. In this study, we explore a hybrid metal\u2013organic framework (MOF) with reduced graphene oxide (rGO) as a SERS active substrate. The developed material showed a good sensitivity for VOC formaldehyde (FA), easily detectable at peak 1452 cm\u22121 and offering an RSD of 16.95%. Since the substrate did not rely on any noble metals for SERS enhancement, this low cost and easy material could be fine-tuned, creating alternative less-toxic materials for detection in industries such as food safety.<\/jats:p>","DOI":"10.3390\/bios15100703","type":"journal-article","created":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:27:29Z","timestamp":1760963249000},"page":"703","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Noble-Metal-Free MIL-101(Cr)@rGO for Formaldehyde SERS Detection"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4135-1435","authenticated-orcid":false,"given":"Harriet Sonia","family":"Nalumansi","sequence":"first","affiliation":[{"name":"State Key Laboratory of Food Science and Resources, School of Food Science and Technology, Jiangnan University, Wuxi 214122, China"},{"name":"Collaborative Innovation Center of Food Safety and Quality Control in Jiangsu Province, Jiangnan University, Wuxi 214122, China"},{"name":"International Joint Laboratory on Food Safety, Jiangnan University, Wuxi 214122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuwei","family":"Pi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Food Science and Resources, School of Food Science and Technology, Jiangnan University, Wuxi 214122, China"},{"name":"Collaborative Innovation Center of Food Safety and Quality Control in Jiangsu Province, Jiangnan University, Wuxi 214122, China"},{"name":"International Joint Laboratory on Food Safety, Jiangnan University, Wuxi 214122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingkun","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Food Science and Resources, School of Food Science and Technology, Jiangnan University, Wuxi 214122, China"},{"name":"Collaborative Innovation Center of Food Safety and Quality Control in Jiangsu Province, Jiangnan University, Wuxi 214122, China"},{"name":"International Joint Laboratory on Food Safety, Jiangnan University, Wuxi 214122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoyong","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Food Science and Resources, School of Food Science and Technology, Jiangnan University, Wuxi 214122, China"},{"name":"Collaborative Innovation Center of Food Safety and Quality Control in Jiangsu Province, Jiangnan University, Wuxi 214122, China"},{"name":"International Joint Laboratory on Food Safety, Jiangnan University, Wuxi 214122, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9979","DOI":"10.1039\/D3TA07171E","article-title":"Nanomaterial-based VOC sensing applications and a deep dive into their developmental trends","volume":"12","author":"Rosario","year":"2024","journal-title":"J.
