However, it needed an additional chemical etching step to open the closed bottom end, and due to the complex fabrication procedures, this cell configuration has not been paid extended attention.
The anodic region (+ 0.7 V) had a good sensitivity of 50.63 μAmM− 1cm− 2 and a lower detection limit of 0.2 mM which is comparable to most of the enzymatic glucose biosensors that involve complex fabrication procedures.
Complex fabrication process and time-consuming.
However, the drawback of the on-chip syringe pump is the complex fabrication method involving a multistructured MEMS procedure.
The use of relevant design rules to generate weld features is discussed in this paper using as an example the design procedure for a complex fabrication.
In terms of fabrication of ZnO MCs, less studies utilized top-down etching technique [8, 9] because it might require complex fabrication steps as well as subsequent precise patterning procedure.
In addition, the fabrication procedure for these electrodes was complex and costly, requiring multiple photolithography, e-beam evaporation, and lift-off process steps.
Although the evaporated Bi WEs performed well (LOD = 60 nM), the fabrication procedure for these electrodes was complex and costly, requiring multiple photolithography, e-beam evaporation, and lift-off process steps.
However, the complex fabrication methods involving high-temperature processes performed in a highly pure environment slow the fabrication process and make amplified components expensive with respect to an ideal, high-throughput, room temperature production.
However, these typically have limited operation bandwidths (a few tens of nanometers) and require complex fabrication and packaging.
