As a newly noninvasive emerging modality, NIR-II fluorescence imaging (1000-1700 nm) has many advantages over conventional visible and NIR-I (700-900 nm). Unfortunately, only few fluorophores are suitable for bone imaging. Here, we report an fluorophore based on DSPE-mPEG encapsulated rare earth doped nanoparticles (RENPs@DSPE-mPEG), which shows inherent affinity to without linking any targeting ligands, thus, it provides alternative nonradiation strategy skeletal system mapping disease...

This work identifies changes in dominant topics library and information science (LIS) over time, by analyzing the 3,121 doctoral dissertations completed between 1930 2009 at North American Library Information Science programs. The authors utilize latent Dirichlet allocation (LDA) to identify diachronically representative of those topics. findings indicate that main LIS have changed substantially from initial period (1930–1969) present (2000–2009). However, some themes occurred multiple...
