Can metal organic frameworks use enhanced fluorescence?5 answersMetal-organic frameworks (MOFs) can exhibit enhanced fluorescence. Doping with inert ligands in MOFs can lead to an increase in fluorescence intensity. The mechanism behind this enhancement is not fully understood, but several possibilities have been ruled out, including exciton coupling, electron transfer, and ligand intersystem crossing induced by the metal center. Inhibition of interligand charge transfer and conformational changes of the ligands within the MOF cavity are proposed as potential ways to enhance emission. Additionally, the presence of special interactions, such as "bilateral π-π stacking" between the host and guest, can facilitate electron transfer and greatly enhance fluorescence intensity. Gold nanoparticles encapsulated in MOFs can also modulate the optical properties of fluorescent molecules and enhance fluorescence. These findings open up possibilities for using MOFs in fluorescent probes, sensing applications, and visual detection of trace compounds.

How does fluoresence microscopy works?5 answersFluorescence microscopy is a technique that allows for the visualization of biological structures at the molecular level by utilizing the fluorescence properties of certain molecules. In conventional optical microscopy, the sample is illuminated with white light and the resulting image is magnified, but contrast is often poor. In fluorescence microscopy, on the other hand, molecules in the sample are excited by a specific wavelength of light and emit light at a different wavelength, resulting in improved contrast. This technique also allows for the detection of structures down to a few nanometers in size, surpassing the diffraction limit of conventional microscopy. Additionally, fluorescence microscopy enables real-time imaging of living cells by using fluorescent tracers attached to cellular components or individual molecules. The advancements in fluorescence microscopy have led to the emergence of new fields such as nanobioimaging and nanomedicine.
Why fluorescence spectroscopy is used in dissolved organic matter analysis?4 answersFluorescence spectroscopy is used in dissolved organic matter (DOM) analysis for several reasons.

How does phenolphthalein indicator work?5 answersPhenolphthalein indicator works by undergoing a color change in response to changes in the pH of a solution. It is commonly used in titration experiments to determine the endpoint of a reaction. When phenolphthalein is in an acidic solution, it remains colorless. However, as the pH of the solution becomes more basic, phenolphthalein turns pink or magenta. This color change occurs due to the dissociation of phenolphthalein molecules into ions in basic solutions. The presence of these ions causes the solution to become colored. The color change of phenolphthalein is reversible, meaning it can go back to being colorless when the pH of the solution becomes acidic again. This property makes phenolphthalein a useful indicator for determining the acidity or basicity of a solution.

5 answers
Pro-amphiregulin (proAR) is a precursor form of amphiregulin (AR), a growth factor that belongs to the epidermal growth factor (EGF) family. It is synthesized as a type I transmembrane protein precursor and expressed on the cell surface before being processed into its active form through ectodomain shedding. This shedding yields a soluble AR that can activate the EGF receptor (EGFR), promoting various cellular responses, including proliferation and survival. The process of shedding also results in a transmembrane-cytoplasmic fragment (AR-CTF), which has distinct cellular trafficking compared to un-shed proAR. ProAR undergoes nuclear translocation, a process independent of the conventional EGFR signaling pathway, where it can influence cellular behavior, including chemoresistance in cancer cells. This nuclear translocation involves the truncation of the C-terminus, which activates an ER-retrieval signal, allowing proAR to interact with nuclear components and participate in chromatin organization and transcription regulation. In the context of reproductive health, the concentration of amphiregulin in follicular fluid has been linked to the developmental potential and quality of embryos after vitrification, suggesting its role in reproductive functions. Moreover, certain iron compounds can induce the expression of amphiregulin in intestinal epithelial adenocarcinoma cell lines, indicating its involvement in cancer and inflammation. Amphiregulin plays a pro-neoplastic role in colorectal carcinogenesis, suggesting potential targets for cancer prevention and treatment.
