体外研究 (In Vitro) |
Pyranine is capable of discriminating ranges of cations from the Cu+ ion, even in competing environment. Pyranine displays a rapid fluorescence response (t1/2=1.66 min) towards the Cu+ ion, and the micromolar detection limit enables the detection of the ion in environmental samples. The observed stoichiometry of complexation between Pyranine and Cu+ is 2:1[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |

Cell Assay [3] |
PAAm-κC composite gels are prepared by free-radical copolymerization using 0.71 g of AAm, 0.01 g of BIS (N, N’-methylenebisacrylamide), 0.008 g of APS (ammonium persulfate) and 2 µl of TEMED (tetramethylethylenediamine) are dissolved in 5 mL of distilled water (pH 6.5) by heating. The heated mixture solution is held at 80°C. Then different amounts of κ-carrageenan (0.5, 1, 1.5, 2, 2.5 and 3 (w/v) % κC) are added. Pyranine (Py) is used in the PAAm–κC composites as a fluorescence probe, which is a derivative of pyrene possessing three SO3– groups, which can form bonds with positive charges on the gel. Pyranine (Py) concentration is kept constant at 4×10-4 M, for all experiments. The solution is stirred (200 rpm) for 15 min to achieve a homogenous sample solution. All samples are deoxygenated by bubbling nitrogen for 10 min just before the polymerization process. The drying and swelling experiments of disc-shaped PAAm–κC composite gels prepared are performed in air and in water, respectively, at various temperatures (30, 40, 50, and 60°C). A model LS-50 spectrometer equipped with a temperature controller is used for fluorescence intensity measurements, which are made at a 90° position and spectral bandwidths are kept at 5 nm. Disc-shaped gel samples are placed on the wall of a 1-cm path-length square quartz cell filled with air and/or water for the drying and swelling experiments[3]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
