The present invention relates to a family of fluorescent compounds based on the BODIPY scaffold, and methods for the preparation of said compounds. The present invention further relates to the use of said compounds for the detection of bacterial biofilms, wherein the bacterial biofilm comprises Pseudomonas aeruginosa and the compound specifically binds to a Fap protein of Pseudomonas aeruginosa, or wherein the compound specifically binds to bacterial cells that contain high levels of cyclic-di-guanosine-monophosphate (c-di-GMP).

The present invention is directed to a fluorescence compound represented by structural Formula (I), with specificity to neural stem cells: (I), or a pharmaceutically acceptable salt thereof. The variables for structural Formula (I) are defined herein. Also described are methods for detection of beta cells, pancreatic islets and microglia cells, comprising using a compound of structural Formula (I) or pharmaceutically acceptable salts thereof. Compounds of structural Formula (I) can also differentiate healthy pancreatic islet cells from diabetic pancreatic islet cells.
Lighting up the pancreas: A pancreatic beta cell selective probePiY (red, see picture) was developed which stains Langerhansislets in live animals without toxicity or side effects. Through tail‐vein injection, PiY allowed for a comparison of the islets between healthy and diabetic mice. PiY also facilitated the isolation of healthy Langerhansislets by using a fluorescence‐guided surgical procedure.
classification of bacteria is the first step of bacterial community research and the treatment of infection. Herein, a fluorescentprobe BacGO is presented, which shows the best universal selectivity for Gram‐positivebacteria among known probes with a minimum staining procedure for sample detection and enrichment of the live bacteria. BacGO could also be used to assess of the Gram status in the bacterial
Small molecule fluorescent probes offer significant advantages over conventional antibody and fluorescent protein labeling techniques. Here we present CDr10a and CDr10b, dyes that label live microglia specifically. They may be applied to the isolation and imaging of live microglia when investigating their role in neuroinflammatory diseases.
