So far the optical properties of nanosheets (NS) of these silicates are poorly understood. Here, we exfoliate them into monodisperse nanosheets, report their physicochemical properties and use them for (bio)photonics. The approach uses ball milling followed by tip sonication and centrifugation steps to exfoliate the silicates into NS with lateral size and thickness down to ≈ 16–27 nm and 1–4 nm, respectively. They emit at ≈ 927 nm (EB-NS), 953 nm (HB-NS) and 924 nm (HP-NS), and single NS can be imaged in the NIR. The fluorescence lifetimes decrease from ≈ 30–100 μs (bulk) to 17 μs (EB-NS), 8 μs (HB-NS) and 7 μs (HP-NS), thus enabling lifetime-encoded multicolor imaging both on the microscopic and the macroscopic scale. Finally, remote imaging through tissue phantoms reveals the potential for bioimaging. In summary, we report a procedure to gain monodisperse NIR fluorescent silicate nanosheets, determine their size-dependent photophysical properties and showcase the potential for NIR photonics."],["dc.identifier.doi","10.1039/D1NA00238D"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/88360"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/324"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-448"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation.eissn","2516-0230"],["dc.relation.workinggroup","RG Enderlein"],["dc.rights","CC BY 3.0"],["dc.rights.uri","http://creativecommons.org/licenses/by/3.0/"],["dc.title","Photophysical properties and fluorescence lifetime imaging of exfoliated near-infrared fluorescent silicate nanosheets"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Recently developed elastic in vitro culture chambers allow for raising 3D muscle tissue under controlled conditions and to measure global tissue force generation. However, these chambers are inherently incompatible with high-resolution microscopy limiting their usability to global force measurements, and preventing the exploitation of modern fluorescence based investigation methods for live and dynamic measurements. Here, we present a new chamber design pairing global force measurements, quantified from post-deflection, with local tension measurements obtained from elastic hydrogel beads embedded in muscle tissue. High-resolution 3D video microscopy of engineered muscle formation, enabled by the new chamber, shows an early mechanical tissue homeostasis that remains stable in spite of continued myotube maturation."],["dc.identifier.doi","10.7554/eLife.60145"],["dc.identifier.pmid","33459593"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/82931"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/118"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation.eissn","2050-084X"],["dc.relation.workinggroup","RG Betz"],["dc.relation.workinggroup","RG Enderlein"],["dc.rights","CC BY 4.0"],["dc.title","Global and local tension measurements in biomimetic skeletal muscle tissues reveals early mechanical homeostasis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
