Therefore, it is expected that Sc-based nanomaterials with unique dominant red UC and DC NIR-II emissions beyond 1500 nm are ideal probes for bio-applications. Moreover, non-invasive through-skull fluorescence bioimaging of brain vessels with high spatial resolution was demonstrated. In vivo NIR-II imaging reveals that our explored Sc-based nanorods are promising probes for highly sensitive optical imaging. The mass also encased the left vagus nerve. More importantly, apart from the dominant red UC emission, these probes also possess a strong NIR-II downconversion (DC) emission centered at 1525 nm, which is usually ignored for bioimaging applications. Attempts were made to completely excise the mass, but this was not possible due to tumor adherence to the skull base. These probes present a dominant red upconversion (UC) emission, which is significantly different from the traditional NaYF 4:Yb/Er host, which usually has a green UC emission. The lanthanide doped Sc-based probes (KSc 2F 7:Yb 3+/Er 3+) possess a pure orthorhombic phase structure with size control by adjusting the F − ion content.

Herein, a new Sc-based NIR-II probe was explored for high performance NIR-II in vivo bioimaging and optical imaging-guided non-invasive brain blood vessel visualization. Compre online Skull Base Imaging, de Midyett, F Allan na Amazon. Optical bioimaging that works in the second near infrared region (NIR-II, 1000–1700 nm) has emerged as a next generation imaging technique with superior imaging sensitivity and spatial resolution compared to traditional optical imaging utilizing visible and near-infrared lights (below 900 nm).
