This is consistent with the increased red fluorescence found in the emission fingerprints of nucleus and nucleoli typical for dye immobilization by high viscosity of its environment due to the highly packed nucleoproteins in nucleoli (Fig. S3 A in Data S1).
For a typical process of protein immobilization, 10 μl HRP solution (15 mg ml−1, 0.01 M PBS, pH 7.0) was dropped onto 0.75 × 0.75 cm2 SnO2 array alloy electrode surface.
In agreement with the results, Stamatis et al. have stated that the typical MBGs used for immobilization of enzymes have a characteristic of high Wo values (Wo > 40) [ 17].
In this work, we developed a new amperometric biosensor for glutamate detection using a typical method of glutamate oxidase (GlOx) immobilization via adsorption on silicalite particles.
It was created using a non-typical method of the recombinant urease immobilization via adsorption on nanoporous particles of silicalite.
Typical DNA-based electrochemical biosensors require an immobilization step of DNA probe as the biological recognition element, which always suffers from time-consuming and labor-intensive electrode pretreatment and immobilization process, expensive chemical modification, lower reactivity, and complicated operation.
All the above factors make GGNR aerogels ideal templates for immobilization of MoS2 nanosheets, a typical noble metal-free hydrogen evolution catalyst.
In this study, for the first time, we use DLS as a sensitive and efficient probe to achieve the kinetic adsorption profile of linear DNA and aptamers on the surface of AuNPs in the typical three-step (aging, salting, and incubation) immobilization process invented by Mirkin.
First of all, to test the efficiency of the proposed method of enzyme immobilization, it was necessary to compare typical responses of the biosensors obtained by the traditional method of immobilization and those with the immobilization by adsorption.
On the other hand, after folic acid immobilization, the GF showed the three typical peaks corresponding to C 1s, N 1s, and O 1s (Figure 5b).
