“…The ease of stably modifying magnetic nanomaterials through aryldiazonium ion grafting to core−shell NPs was exploited by Matysiak-Brynda et al 161 who deposited carboxyphenyl and aminoethylphenyl layers on Fe@C NPs physisorbed on gold electrodes. After a monoclonal antibody for ferritin was coupled to the anchor layers, both the interaction of ferritin with the sensing surface and the electrochemical detection of ferritin were examined in the presence and absence of an external magnetic field.…”

“…Electrochemical methods are often attractive in clinical diagnostics settings, due to their ease of operation, minimal sample preparation, and easy data interpretation [11]. Recently, ferritin detection using electrochemical techniques has gained attraction [12,13], employing static systems [12][13][14][15][16][17][18]. Researchers of this manuscript have also recently reported the use of biosurfactant functionalized tungsten disulfide quantum dots for the electrochemical detection of ferritin using screen printed electrodes as a platform [19].…”

“…The influence of antibody attachment to the phenyl films containing either -COOH or -NH 2 groups on the efficiency of antibody ferritin binding has been reported by Matysiak-Brynda and co-workers. The authors have observed that the vertical orientation of antibody vs the electrode surface could be achieved by its binding to aminoethylophenyl linkers leading to the increasing efficiency of sensor toward electrochemical detection of ferritin [26]. ∆I = I n − I, which means: I n -value of the peak current measured in the presence of particular "n" concentration of LDL, recorded at the potential of maximum peak current value registered in buffer, I-value of peak current measured in a solution free of LDL, in buffer.…”
