Tuning the Photophysical Properties of BODIPY Dyes and Studying Their Self-Assembly via Hydrogen Bonding.

Here, BODIPY derivatives were functionalized with barbituric acid, which has multiple hydrogen bonding abilities that are directional, to have highly ordered hydrogen bond-mediated self-assembled structures to tune BODIPY's photophysical properties. The synthesis of barbituric acid-functionalized BODIPY derivatives via Vilsmeier and Knoevenagel reactions was achieved, and the resulting compounds were characterized with FT-IR, H NMR, C NMR spectroscopy, and mass spectrometry. Hydrogen bond-mediated self-assembled structures were investigated through UV-vis and fluorescence spectrophotometry, H NMR spectroscopy, and a dynamic light scattering method in solution.

A foundation model for generalizable disease detection from retinal images.

Medical artificial intelligence (AI) offers great potential for recognizing signs of health conditions in retinal images and expediting the diagnosis of eye diseases and systemic disorders. However, the development of AI models requires substantial annotation and models are usually task-specific with limited generalizability to different clinical applications. Here, we present RETFound, a foundation model for retinal images that learns generalizable representations from unlabelled retinal images and provides a basis for label-efficient model adaptation in several applications.
