Some Recent Designs and Developments of Screen‐Printed Carbon Electrochemical Sensors/Biosensors for Biomedical, Environmental, and Industrial Analyses
TL;DR: In this paper, the design and fabrication of electrochemical sensors/biosensors based on screen-printing technology and their applications in pharmaceutical, biomedical, environmental, and industrial analyses are described.
Journal ArticleDOI
An electrochemical biosensor to simultaneously detect VEGF and PSA for early prostate cancer diagnosis based on graphene oxide/ssDNA/PLLA nanoparticles
TL;DR: A novel fabrication method for producing a dual-modality biosensor that can simultaneously detect vascular endothelial growth factor (VEGF) and prostate-specific antigen (PSA) in human serum for early diagnosis of PCa is reported.
Journal ArticleDOI
Biosensors for plant pathogen detection
TL;DR: The use of different nanomaterials such as nanochannels and metallic nanoparticles for the development of innovative and sensitive biosensing systems for the detection of pathogens at the point-of-care is shown, offering cheap and easy-to-use really integrated sensing systems for rapid on-site detection.

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.
