The development of a novel and simple inhibition biosensor array for detection of water pollutants based on immobilized bacteria is the main goal of this work. A series of electrochemical measurements (i.e. cyclic voltammograms) were carried out on screen-printed gold electrodes with three types of bacteria, namely Escherichia coli, Shewanella oneidensis, and Methylococcus capsulatus, immobilized via poly L-lysine. For comparison purposes, similar measurements were carried out on bacteria samples in solutions,; also optical measurements (fluorescence microscopy, optical density, and flow cytometry) were performed on the same bacteria in both liquid and immobilized forms. The study of the effect of heavy metal ions (lead), pesticides (atrazine) and petrochemicals (hexane) on DC electrochemical characteristics of immobilized bacteria revealed a possibility of pattern recognition of the above inhibition agents in aquatic environment.

“…[6][7][8][9][10][11] In recent years, methods employing collision/reaction gas cells using He, H2, NH3, CH4, or O2 have been introduced into ICP-MS to remove the interferences of coexisting ions. [12][13][14][15][16] In particular, when He is used as the collision gas, spectral interferences caused by molecular ions are effectively reduced. All ions in the collision/reaction cell lose their kinetic energies in collision with He atoms, but molecular ions lose more kinetic energy than do elemental ions.…”

“…5 In recent years, collision/reaction cells filled with He, H2, NH3, or CH4 have been employed to remove the interferences of coexisting ions. [6][7][8][9][10][11] Especially, a reaction cell with O2 gas is extremely useful for As measurements, since As can be measured as AsO + at m/z = 91 while being free from the spectral interference of 40 Ar 35 Cl + and 40 Ca 35 Cl + . This technique is widely used for the analysis of food as well as environmental and biological samples.…”
