“…As shown in Figure 3, the maximum ECL intensity could be obtained at pH 8.5. It is reported that the pH for optimal GDH activity is at 8.5, and the ECL intensity in the detection of NADH keeps nearly constant when pH is above 5.5 [19,20]. The observed ECL response was the integrated result of both enzyme catalysis and ECL reactions.…”

A novel electrochemiluminescence (ECL) sensing approach was developed for glucose detection based on crosslinking Ru(bpy) 3 Cl 2 -doped silica nanoparticles (RuSiNPs) with glucose dehydrogenase on a glassy carbon electrode (GCE). Glutaraldehyde and aminopropyltrimethoxysilane were used as linking agents, and chitosan was used to immobilize the composites onto the GCE surface. The ECL sensor presented good characteristics in terms of stability and reproducibility. Under optimized conditions, the linear response of ECL intensity to glucose concentration was valid in the range of 0.2 to 20 mmol/L (R 2 = 0.9962). The application results indicated that the proposed approach is with great potential in the determination of glucose.

“…The second type was based on the utilization of glucose dehydrogenase enzyme for enzymatic reaction, in coupling with tris(2,2′-bipyridyl) ruthenium (II) complex for CL reaction. 49 This sensor can be used on 10 to 2500 µmol/l concentration range. There are a lot of interferences like NADH, oxalate, proline, and tripropylamine.…”

“…11 Vycor glass is formed by the selective etching of the more soluble phase from a phase-separated borosilicate glass. Recently, it has been receiving renewed attention as these glasses find new applications as substrates for biosensing, [12][13][14] bioreactors, 15,16 precise filtration, 17 and chromatography. 18 Analogous techniques are being applied to crystalline ceramics, such as the directed cooling of eutectics to drive phase separation with the subsequent preferential dissolution of one phase.…”

Controlled pore glasses are formed through selective etching of one phase of a spinodally decomposed borosilicate glass, an old technique that is the basis of the porous Vycor synthesis technique developed in the 1920s. This technique is receiving renewed attention as these glasses find new applications as substrates for biosensing, bioreactors, precise filtration, and chromatography. Analogous techniques are being applied to crystalline ceramics, such as directed cooling of ZrO 2 /MgO and MgAl 2 O 4 /Al 2 O 3 eutectics to drive phase separation with the subsequent dissolution of one phase. Pyrolytic reactive sintering is a combination of the phase separation method and the reactive sintering method to obtain a 3D porous structure network. For example, dolomite (CaMg[CO 3 ] 2 ) and ZrO 2 yield a uniformly porous CaZrO 3 /MgO composite that utilizes evolved CO 2 as a "pore-forming agent." This article gives an overview of recent developments on meso-and macroporous ceramics based on phase separation and reactive sintering technologies.
