A novel cobalt hexacyanoferrate nanocomposite on CNT scaffold by seed medium and application for biosensor

In situ precipitation of Nickel-hexacyanoferrate within multi-walled carbon nanotube modified electrode and its selective hydrazine electrocatalysis in physiological pH

“…9A(b) inset) with current sensitivity of 19.7 lA/mM, which is about 20 times sensitive over the sol-gel modified Ni-NCFe ($1 lA/mM) [9]. Such an enhanced catalytic activity for the GCE/ Ni-NCFe@f-MWCNT electrode could originate from a combination of an increased availability of inner-walls-bound Ni-NCFe sites within the f-MWCNT and macro-molecular Ni-NCFe units precipitated on the CNT surface that is clearly distinct from the traditional ex-situ preparation approach [11,12,[26][27][28][29], where the catalyst particles were assembled/adsorbed exclusively on the external surface of the CNT. Extended amperometric detection methods as in Fig.…”

Electrochemical preparation of copper hexacyanoferrate nanoparticles under the synergic action of EDTA and HAuCl4

“…As a result, metal hexacyanoferrates nanoparticles modified electrodes have also been investigated [12][13][14][15][16][17][18][19][20][21][22][23][24]. Baioni et al [12,13] synthesized copper hexacyanoferrate nanoparticles and the nanoparticles were immobilized on the surface of ITO electrodes by the method of self-assembled layers.…”

Amperometric glucose sensor based on glucose oxidase immobilized on gelatin-multiwalled carbon nanotube modified glassy carbon electrode

“…With high mechanical strength, excellent conductivity and antifouling properties, multiwalled carbon nanotubes (MWCNTs) have been immensely used in glucose sensors for GOx immobilization [2]. Some of the recently reported MWCNT matrices for GOx immobilization are ionic liquid n-octylpyridinum hexafluorophosphate dispersed MWCNT [3], MWCNT/gold nanoparticlesTeflon composites [4], Chitosan dispersed MWCNT [5], gold nanoparticles/thiol group functionalized MWCNT/Chitosan-ionic liquid [6], cobalt hexacyanoferrate nanoparticles/gold nanoparticles (seed)/ MWCNT composites [7], crystalline gold nanoparticles modified MWCNT [8], platinum nanoparticle/MWCNT composites [9], nitrogen doped MWCNT [10] and polymerized ionic liquid-wrapped MWCNT [11]. The inclusion of MWCNT into the immobilization matrix leads to the high sensitivity and good stability of the immobilized enzyme [3].…”
