Inulin is an orally active prebiotic targeting the intestinal microbiota, selectively promoting the proliferation and activity of beneficial bacteria such as bifidobacteria and lactic acid bacteria, and playing a role in regulating the intestinal microecology. The functions of Inulin include: Fermentation by probiotics in the colon to produce short-chain fatty acids (such as butyrate and propionate), lowering the intestinal pH and inhibiting the overgrowth of harmful bacteria; Enhancing the intestinal barrier function and reducing endotoxin translocation; Directly scavenging free radicals (such as superoxide free radicals, hydroxyl free radicals) and activating antioxidant enzymes (SOD, CAT) to reduce oxidative stress. Inulin can also be used in the study of intestinal diseases (constipation, IBD), metabolic syndrome (diabetes, obesity) and liver damage by regulating glucose and lipid metabolism (such as reducing triglycerides, improving insulin sensitivity) and immune response (enhancing NK cell activity, inhibiting inflammatory factors)[1][2][3][4].

2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .

HKSOX-1 and its derivatives (HKSOX-1r and HKSOX-1m) are novel fluorescent probes designed for highly sensitive and selective detection of the superoxide anion radical (O2 •−) in cellular environments. These probes utilize an aryl trifluoromethanesulfonate group that undergoes O2 •−-mediated cleavage, releasing a free phenol and emitting fluorescence. They demonstrate excellent specificity and sensitivity across various pH ranges, withstand interference from strong oxidants and reductants typical in cellular contexts. HKSOX-1r, optimized for cellular retention, has been effectively employed in diverse assays including confocal imaging, flow cytometry, and zebrafish embryo studies, highlighting its utility in investigating O2 •− roles in inflammation, mitochondrial stress, and other physiological processes .

Poly (sodium 4-styrenesulfonate) is an anionic cation-exchange polyelectrolyte and metal ion binding/retention agent. It selectively retains Cr III and Fe II under pH 1 conditions, and its retention effect on all tested metal ions is enhanced under higher pH conditions. Poly (sodium 4-styrenesulfonate) inhibits nanosheet aggregation through edge-face interactions between aromatic rings and the graphite surface, thereby stabilizing the dispersion of reduced graphene oxide nanosheets. When incorporated into the mixed Nafion coating of bismuth film electrodes, Poly (sodium 4-styrenesulfonate) improves the reproducibility, stability, sensitivity, and anti-fouling capability for trace metal detection .
