Development of electrochemical sensor based on polyalanine/CuCl-Gr/DWCNTs for highly sensitive detection of glyphosate

Development of a Disposable Aptasensor Using Carboxymethyl Cellulose and Hydroxyapatite Nanoparticles for Voltammetric Detection of Glyphosate

“…Table SIX represents recently developed electrochemical (bio) sensors for the detection of GLY. 37,39,[43][44][45][46][47][48][49][50][51][52][53][54][55] Although low detection limits were reached by using these reported (bio)sensors, most of them required to apply exhausted experimental steps that included the use of intensive chemical agents or heat applications. The molecularly imprinted polymers (MIPs) based electrochemical sensor platforms [44][45][46] were fabricated by following the experimental steps including synthesizing monomer and GLY-specific polymers, modification of these polymers at selected electrode surfaces, the interaction process and the electrochemical measurements.…”

“…There are enzyme based electrochemical biosensor platforms in the literature for the electrochemical detection of GLY. 48,49,53 As an example, Thanh and coworkers 48 developed polyalanine copper chloride doped graphene/double-walled carbon nanotubes (PolyA/ CuCl-Gr/DWCNTs) modified gold electrode (AuE) for voltammetric detection of GLY. This biosensor platform could detect GLY in a sensitive and selective way.…”

“…However, its construction process could not be evaluated as environmentally safe and labor friendly. The researchers who wants to fabricate the biosensor platform by following the protocol reported by Thanh et al 48 should synthesize the nanocomposite structure and modify this structure on screen printed gold electrode surface. The synthesis and modification steps are required to apply high temperature levels and to use complex chemical agents.…”
