Disposable Biosensors for Clinical Diagnosis

Abstract: We present an overview on the use of disposable electrochemical biosensors for diagnostics, focusing on the applications of these devices as immunosensors and DNA sensors in the point-of-care diagnostics. Analytical biosensors have emerged as efficient alternatives for the detection of innumerous diseases, because of their high specificity and the convenience of detecting the electrochemical signals produced by the presence of an analyte using a portable equipment. This review highlights the recently developed… Show more

“…Electrochemical biosensors are selective devices using a biological recognition element immobilized on the transducer [14,15]. Biosensors are able to provide quantitative or semiquantitative analytical information, which transforms the biorecognition reaction of the analyte to a measurable signal.…”

“…Biosensors are able to provide quantitative or semiquantitative analytical information, which transforms the biorecognition reaction of the analyte to a measurable signal. These devices may be applied in different areas, such environmental, medical, biological, pharmaceutical, or industrial [14,15]. In order to obtain a sensitive electrochemical biosensor based on CB, several architectures can be obtained in the preparation of the electrode surface such as monolayer, multilayers, and thin films.…”

“…Such properties combined with the potential applications of nanotechnology have made such materials very attractive for development of electrochemical sensors [8][9][10][11][12] and biosensors [13][14][15][16]. Indeed, stable dispersions have been prepared with nanomaterials for electroanalysis [17,18], which provides good stability and do not interfere in the electron transfer at electrode/solution interface.…”

“…With higher specificity than PSA, PCA3 is expected to play more important roles in clinical practice such as prostate cancer screening, grading and recurrence monitoring (22 stability and lack of a purification method from complex matrix. Nanotechnology has highly influenced biomedical research and clinical laboratory practice (23)(24)(25). Magnetic beads are nano-sized or micro-sized ferromagnetic iron oxide particles.…”
