A bi-enzymatic whole cell conductometric biosensor for heavy metal ions and pesticides detection in water samples.
A conductometric biosensor using immobilised Chlorella vulgaris microalgae as bioreceptors was used as a bi-enzymatic biosensor. Algae were immobilised inside bovine serum albumin membranes reticulated with glutaraldehyde vapours deposited on interdigitated conductometric electrodes. Local conductivity variations caused by algae alkaline phosphatase and acetylcholinesterase activities could be ...
متن کاملMicrofluidic Enzymatic Sensor for the Electrochemical Detection of Pipemidic Acid in Pharmaceutical Samples
INTRODUCTION Pipemidic acid (PA) is a synthetic quinolone that belongs to the first generation of this kind of compounds, which is used as antibacterial agent. The antibacterial property of the quinolones is associated with their potential to inhibit the bacterial topoisomerase II (1). PA is widely used for the treatment of urinary tract infections, showing high activity against gram-positive a...
متن کاملEarly detection of cardiac ischemia using a conductometric pCO2 sensor
For detection of cardiac ischemia based on regional pCO2 measurement, sensor drift becomes a problem when monitoring over several hours. A real-time drift correction algorithm was developed based on utilization of the time-derivative to distinguish between physiological responses and the drift, customized by measurements from a myocardial infarction porcine model (6 pigs, 23 sensors). IscAlertT...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
Conductometric Sensor for Soot Mass Flow Detection in Exhausts of Internal Combustion Engines
Soot sensors are required for on-board diagnostics (OBD) of automotive diesel particulate filters (DPF) to detect filter failures. Widely used for this purpose are conductometric sensors, measuring an electrical current or resistance between two electrodes. Soot particles deposit on the electrodes, which leads to an increase in current or decrease in resistance. If installed upstream of a DPF, ...
