Electrochemical Biosensors for Cancer Biomarker Detection
TL;DR: The status, the latest research and trends of electrochemical sensors in the quantitation of cancer markers in recent years are described and the strategy to improve the sensitivities of the electrochemical biosensors by the aid of enzymatic amplification, nanoparticle amplification, ultilization of magnetic microspheres etc is described.
Journal ArticleDOI
Label-free electrochemical aptasensing of the human prostate-specific antigen using gold nanospears.
TL;DR: The nanospears were employed as a transducer to immobilize an aptamer of prostate-specific antigen (PSA) and fabrication of a label-free electrochemical aptasensor, which was successfully applied to detect PSA in blood serum samples of healthy and patient persons.

TL;DR: Good selectivity and superb stability over more than 8 weeks was also demonstrated using these Au NRs@TiO2 heterostructures for glucose (lactose) detection without the addition of enzymes.
Journal ArticleDOI
Label-free electrochemical detection of prostate-specific antigen based on nucleic acid aptamer.
TL;DR: A label-free aptasensor to make direct detection of prostate specific antigen (PSA, a biomarker of prostate cancer) using a quinone-containing conducting copolymer acting as redox transducer and grafting matrix for immobilization of the short aptamer strands is reported.

The steady-state kinetics of peroxidase with 2,2′-azino-di-(3-ethyl-benzthiazoline-6-sulphonic acid) as chromogen
R E Childs,W G Bardsley +1 more
TL;DR: An interpretation of the results is given which requires some extension of the classical peroxidase mechanism, and a study of the steady-state kinetics over a whole range of substrate concentrations is reported.

TL;DR: Results indicate that PA is a histiotypic product of the prostate and may be of use as an adjunctive tool in diagnostic procedures of prostate cancer.
Journal ArticleDOI
Use of polymer films in amperometric biosensors
TL;DR: The use of polymeric films as a medium to incorporate mediators, while an important function, is too vast for review here as mentioned in this paper, and the applications of polymer film-modified biosensors for selected analytical determinations are also presented.
Journal ArticleDOI
Novel immunoassay for the measurement of complexed prostate-specific antigen in serum
TL;DR: Both the serum concentration and the proportion of complexed PSA was substantially higher in patients with CaP compared with patients with benign prostate disease, and the cPSA assay may have utility in improving specificity in screening for prostate cancer.
Journal ArticleDOI
Screen-printed amperometric biosensors for the rapid measurement of L- and D-amino acids
TL;DR: The biosensor compares favourably with a standard photometric amino acid test and was used to monitor milk ageing effects and the assay is cheap, simple to perform and rapid, requiring only buffer-electrolyte and a small sample volume.
