Colorimetric detection of glucose using lanthanum-incorporated MCM-41

A comparative study of Zr, Al or Sr doped Mn/MCM-41 for NH3-SCR and resistance to SO2/H2O

“…4(a)), consistent with the results observed in the literature. 40 After Mn, Zr, Sr, and Al are impregnated onto MCM-41, as shown in Fig. 4(b)–(e), there is some sheet structure and small particle agglomeration, indicating that the morphology has changed.…”

BODIPY Immobilized MCM‐41 Based Multianalyte Sensor: Application in Detection and Removal of Trivalent (Al3+, Cr3+) and Divalent (Cu2+, Hg2+) Metal Ions in Aqueous Media

“…The Si−O−Si bond stretching vibrations for MCM‐41 were seen at 1064 and 807 cm −1 (Figure 1). [75] Having an attached hydroxyl group (Si−OH) on the mesoporous MCM‐41 surface causes a wide O−H stretch vibration at 3377 cm −1 [76] . The wide pattern at 3377 cm −1 in the FTIR spectra of MCM‐41 disappears when it is functionalized with L‐propylsilyl ( 4 ) (Figure 1), indicating that the silanol group of L‐propylsilyl has been bonded to the surface of MCM‐41.…”

“…[75] Having an attached hydroxyl group (SiÀ OH) on the mesoporous MCM-41 surface causes a wide OÀ H stretch vibration at 3377 cm À 1 . [76] The wide pattern at 3377 cm À 1 in the FTIR spectra of MCM-41 disappears when it is functionalized with L-propylsilyl (4) (Figure 1), indicating that the silanol group of L-propylsilyl has been bonded to the surface of MCM-41. Additionally, the SiÀ OÀ Si bond emerged as a very strong peak at 1064 cm À 1 in the FTIR spectrum of MS4.…”

Portable and Intelligent Urine Glucose Analyzer Based on a CdTe QDs@GOx Aerogel Circular Array Sensor

“…Researchers use this Raman spectrum change to determine the UG concentration to be measured. In colorimetric detection, glucose produces H 2 O 2 under the action of glucose oxidase, and hydrogen peroxide changes the color of the color probe; commonly used color probes are quantum dots (QDs), , metal nanoparticles, , TMB, − etc. The above methods have been widely used in UG detection; these methods have a wider linear range, high sensitivity, and a low detection limit.…”
