Nonenzymatic free-cholesterol detection via a modified highly sensitive macroporous gold electrode with platinum nanoparticles

Polymer thin films embedded with metal nanoparticles for electrochemical biosensors applications

“…Further, macroporous Au-/nPts electrode was fabricated by electroplating PtNPs onto a coral-like shaped macroporous Au electrode structure using polymer and surfactant template for cholesterol detection (Lee and Park, 2010).…”

Electrochemical oxidation of cholesterol

“…The third class represents sensors based on the direct electrochemical oxidation of cholesterol. The authors claim that the process occurs on nanoporous electrodes such as Pt [ 75 ], Ag [ 76 ], Au/Pt [ 77 ], and Cu 2 S [ 78 ]. However, apart from the increase of the registered current, there is no evidence that cholesterol is electrochemically oxidized.…”

Development of non-enzymatic cholesterol electrochemical sensor based on CuO(NPs)-Polyaniline-Murexide composite

“…Sensors are one of the most developed devices according to their potential applications in several elds like clinical diagnostics, environmental and bioprocess monitoring. Cholesterol is one of the main constituents of mammalian cell membranes as well as cholesterol is a precursor of other biological materials [1]. The detection of cholesterol has received a lot of attention because high cholesterol blood levels can increase risks of heart diseases such as atherosclerosis, high blood pressure and myocardial infraction [2].…”
