“…Using the optimum amount of AgNPs (48 pmol) the sensitivity, when compared to that without using AgNPs, was higher by 2.8 times whereas only 1.7 times (6.2:3.6 −nF cm −2 (log M) −1 ) was obtained in the previous work [14]. When compared with results from other workers [37,38], the detection limit of HSA in this work was very much lower, i.e., about 10 orders of magnitude, the detection limit of MCLR was lowered by 1-3 orders of magnitude [39,40] and the detection limit of Pen G was lowered by 7-8 orders of magnitude [41,42].…”

Algal blooms are a frequent phenomenon in nearly all kinds of fresh water. Global warming and eutrophication by waste water, air pollution and fertilizers seem to lead to an increased frequency of occurrence. Many cyanobacteria produce hazardous and quite persistent toxins, which can contaminate the respective water bodies. This may limit the use of the raw water for many purposes. The purification of the contaminated water might be quite costly, which makes a continuous and large scale treatment economically unfeasible in many cases. Due to the obvious risks of algal toxins, an online or mobile detection method would be highly desirable. Several biosensor systems have been presented in the literature for this purpose. In this review, their mode of operation, performance and general suitability for the intended purpose will be described and critically discussed. Finally, an outlook on current developments and future prospects will be given.

“…They have been found to be harmful to humans, acting as inhibitors of protein phosphatases [1], and as tumor promoters for the acute hepatotoxicity [2]. Although not toxic to fish, microcystins can become enriched to levels that might lead to consumption by humans of amounts above the maximum concentration recommended for drinking water [3].…”
