Detection of both biological and chemical environmental toxicants is essential in the assessment of risk to human health. Cell-based biosensors are capable of activity- based detection of toxicity. Chromatophore cells, responsible for the pigmentation of poikilothermic animal, have shown immense potential as cell-based biosensors in the detection of a broad...
Bacterial contamination of food poses a great risk to human health worldwide. A
chromatophore cell-based biosensor, utilizing B. splendens erythrophore cells, is an
emerging technology that has shown potential to detect bacterial toxicity based on
function-dependent mechanisms. Previous studies have investigated the response of
erythrophore cells to foodborne pathogens, pesticides,...
High specificity to certain class of chemical and biological agents makes
biosensors unreliable for the detection of unknown agents. Also, the analytical
techniques are subject to systematic errors based on the mechanism of detection
leading to false negative and false positive results. Therefore, the results of these
analyses must be...
