Electrochemical fabrication of ZnO-polyvinyl alcohol nanostructured hybrid film for application to urea biosensor

Disposable urea biosensor based on nanoporous ZnO film fabricated from omissible polymeric substrate

“…The results exhibited good consistency and precision between the two methods and confirmed that the proposed method was useful for application in real samples providing good precision and accuracy [41,44]. Table 1 …”

“…The Modified Randles equivalent circuit was applied for the analysis of the EIS data(Fig. 6A, inset)[41,44].…”

Novel I–V Disposable Urea Biosensor Based on a Dip‐coated Hierarchical Magnetic Nanocomposite (Fe3O4@SiO2@NH2) on SnO2:F Layer

“…Numerous immobilization strategies can be adopted, such as adsorption, entrapment and encapsulation, covalent bonding, and cross‐linking. Covalent attachment of the biomolecule to the substrate is one of the most popular immobilization approaches available, although others such as adsorption, entrapment, and cross‐linking are also used …”

“…The Fe 3 O 4 @SiO 2 @NH 2 /SnO 2 :F substrate was then washed and kept in PBS until use. The covalent attachment of Urs to Fe 3 O 4 @SiO 2 @NH 2 /SnO 2 :F was expected to provide the Urs/Fe 3 O 4 @SiO 2 @NH 2 /SnO 2 :F biosensor . Step‐by‐step monitoring of the Urs/Fe 3 O 4 @SiO 2 @NH 2 /SnO 2 :F biosensor fabrication was performed using electrochemical methods.…”

An investigation on the effect of electrodeposited nanostructured ZnO on the electron transfer process efficiency of TiO2 based DSSC

“…Although the above mentioned methods represented the proper results, some of their disadvantages such as time consuming and difficulties have attracted more attention to find the more convenient and feasible deposition methods. Therefore, in our group, electrochemical deposition by taking many advantages as a reliable, cost-effective, convenient and mild physicochemical method has been considered as an important issue for preparation of ZnO nanostructured hybrid films [15,16]. The other often cited advantages of electrodeposition include; high deposition speed, no need for vacuum system, no use of toxic gases, easy scale up and maintenance, the commercial feasibility of the process, tuning the process parameters, and controlling bath conditions (pH, precursor concentration, temperature, solvent, deposition potentials and times) [17][18][19][20][21], which can make it applicable method for modification of solar cell photoanodes.…”
