Therefore, realizing virus detection at low temperatures is a great challenge. Subzero temperatures change the state of the water-soluble substrate, increasing the difficulty of detection. In this work, we designed a novel enhancement substrate to obtain SERS signals of biomolecules stably at low temperatures. For the first time, methanol solvent was introduced into the aqueous system of silver nanoparticles modified with iodide ions. The introduction of methanol solvent not only serves as an anticoagulant to keep the system stable at low temperatures, but it can also improve nanoparticles and form a “hot spot”, which is more suitable for virus detection. This low-toxicity, rapid, and highly sensitive in situ detection technique lays the foundation for the development of SERS technology in the field of food and life sciences.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":9.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142404063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed a woven, thermally adaptive smart textile (TAST) with high solar reflectance and selective infrared emittance and transmittance using a scalable coaxial extrusion method to continuously manufacture core–sheath fibers. TAST enables passive outdoor radiative cooling by 6–10 °C compared to normal fabrics while preserving good mechanical strength, breathability, and washability. Due to the integration of capacitive sensing, radiative cooling, and Joule heating into the woven fibers, TAST can detect the physiological signals of the human body and adapt its thermoregulation function in response to changes in the ambient temperature and perspiration level. The superior intelligence and multifunctional performance of TAST represent a paradigm shift beyond current personal thermal management technologies for enhancing human health, wellness, and performance.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":9.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142408601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
