Watsonia meriana flower like Fe3O4/reduced graphene oxide nanocomposite for the highly sensitive and selective electrochemical sensing of dopamine

Iron-Based Nanomaterials/Graphene Composites for Advanced Electrochemical Sensors

“…Flower like Fe 3 O 4 -reduced graphene oxide nanocomposite [ 97 ] and rGO decorated with p-toluenesulfonate-doped polypyrrole/Fe 3 O 4 nanoparticles [ 92 ] were other two composites which were successfully applied for ultrasensitive detection of dopamine with detection limits of 5 nM and 2.33 nM. In an attempt for determination of uric acid, a nanocomposite was prepared by incorporating Fe 3 O 4 onto graphene sheets followed by depositing of SiO 2 layer on the surface of the Fe 3 O 4 -rGO composites [ 79 ].…”

One-step in situ Controllable Synthesis of MnFe2O4/rGO Nanocomposite and Its Application to Electrochemical Sensing of Hydrogen Peroxide

“…In addition, sensors based on MFe 2 O 4 usually have problems such as low sensitivity and narrow linear range. (14,15) Therefore, it is necessary to modify the surfaces of magnetic nanoparticles by an appropriate method to overcome these limitations. (16,17) A two-dimensional layered nanomaterial, graphene, has received extensive attention owing to its unique electrical, thermal, mechanical, and chemical properties, and has good application prospects in environmental detection and repair, energy conversion, energy storage, and biosensing.…”

Development of an Fe3O4@Cu silicate based sensing platform for the electrochemical sensing of dopamine

“…Therefore, synthesis of Fe based nanocomposites have gained worldwide attention and in the recent past, several Fe nanocomposites based sensing platforms have been developed for the high sensitive detection of DA. [47][48][49][50][51][52][53][54][55][56][57][58][59] For example, Zhang et al demonstrated that Fe 2 O 3 -graphene-polyimide aerogel nanocomposites could be used in the detection of DA. 47 In another study, Adekunle et al synthesized SWCNT-Fe 2 O 3 nanocomposites and used them in the detection of DA.…”

“…50 Rani et al demonstrated that RGO-Fe 3 O 4 ower nanocomposite is a potential material for the highly sensitive and selective electrochemical detection of DA. 51 Sulaiman et al, Bagheri et al and Teymourian et al have synthesized Fe 3 O 4 -RGO nanocomposites and used these nanocomposites in the electrochemical sensing of DA. [52][53][54] In another study, Wu et al demonstrated the synthesis of mesoporous Fe 3 O 4 decorated over the graphene sheets which delivered much better DA sensing performance.…”
