Low cost, simple three dimensional electrochemical paper-based analytical device for determination of p-nitrophenol

A novel paper-based device coupled with a silver nanoparticle-modified boron-doped diamond electrode for cholesterol detection

“…This platform became a new alternative analytical device and was applied in many application areas [14][15][16][17][18][19]. Their simplicity of fabrication, portability and disposability coupled with the small volume of reagent/sample solution required for PADs make them suitable and very appealing for the development of new clinical diagnostic tools.…”

Electroanalysis moves towards paper-based printed electronics: carbon black nanomodified inkjet-printed sensor for ascorbic acid detection as a case study

“…The test zone of the electrochemical cell was then loaded with glucose oxidase, lactate oxidase, and uricase to detect glucose, lactate, and uric acid, respectively. After this pioneering work, several electrochemical paper-based sensors were developed using different paper-based substrates, such as Japanese paper [9], standard filter paper (e.g., Cordenons) [10], office paper [11], and chromatography paper (e.g., Whatman #1), [12,13]). However, these paper types are not suitable for printed electronics since the substrate should be characterized by minimized roughness and low humidity sensitivity.…”

A facile approach for synthesizing molecularly imprinted graphene for ultrasensitive and selective electrochemical detecting 4-nitrophenol

“…The limit of detection is calculated to be 5 nM (S/N = 3). Additionally, the performance of our GR/MIPs sensor was compared with those of other previously reported electrochemical sensors [35,[37][38][39][40][41][42][43] for detecting 4-NP, as shown in Table 1. It can be seen that the GR/ MIPs sensor offered lower detection limit than most of other sensors.…”
