Mediator free highly sensitive polyaniline–gold hybrid nanocomposite based immunosensor for prostate-specific antigen (PSA) detection
TL;DR: In this article, the results of electrochemical studies suggest that AuNPs increase the electroactive surface area of PANI and result in high electron transport in a mediator free electrolyte.
Journal ArticleDOI
A portable chemiluminescence imaging immunoassay for simultaneous detection of different isoforms of prostate specific antigen in serum.
TL;DR: The proposed CL imaging immunoassay possess high throughput and acceptable reproducibility, stability and accuracy, which made it great potential to available to distinguish different isoforms of PSA in serum samples.
Journal ArticleDOI
A molecularly imprinted electrochemical nanobiosensor for prostate specific antigen determination.
TL;DR: An electrochemical nanobiosensor designed and fabricated using a molecularly imprinted polymer for the simple and fast PSA detection demonstrated a fast rebinding rate and a high capacity of PSA recognition with detection limit of 2.0 pg mL-1.
Journal ArticleDOI

Manabu Kuriyama,Ming C. Wang,Lawrence D. Papsidero,Carl S. Killian,T Shimano,Luis A. Valenzuela,Tsuneo Nishiura,Gerald P. Murphy,T. M. Chu +8 more
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.
