A comparison study between a disposable electrochemical DNA biosensor and a Vibrio fischeri-based luminescent sensor for the detection of toxicants in water samples

Multiparametric probe as screening test for quality and safety evaluation in foods

“…These results were comparable with those ones of the toxicity sensor described in literature based on luminescent bacteria [29] as biological system and better than those ones obtained by the electrochemical DNA biosensor [15] and the sensor based on immobilized cyanobacteria [28].…”

“…Also tyrosinase enzyme inhibition has been recently used with increasing frequency to determine different types of pesticides [5,14]. Different electrochemical sensors for the determination of toxicity of water [15,16] and soil [17] due to presence of heavy metals [18] or Polycyclic Aromatic Hydrocarbons (PAHs) [17] consisting in exposing biological organisms to polluted materials are described on literature.…”

Chapter 7. Detection of Damage to DNA Using Electrochemical and Piezoelectric DNA-Based Biosensors

“…The results showed a promising correlation between two tests used for the detection of toxic compounds in water samples. 76 Also other toxicity tests, such as the comet test, show a similar trend when a standard solution as well as real samples are analysed, thus confirming the powerful application potential of these rapid and inexpensive devices. Another similar investigation of potential chemotherapeutics was reported.…”

Studies on sildenafil citrate (Viagra) interaction with DNA using electrochemical DNA biosensor

“…Tencaliec et al (2006) reported a disposable electrochemical DNA biosensor to monitor toxicants in water samples. The oxidation signal of the guanine base, obtained by a square wave voltammetric scan, was used as analytical signal to detect the DNA damage.…”
