The main focus of our study was to implement a rapid, inexpensive and reliable method that could be utilized to check the cereals for safety (i.e., screening for total aflatoxins, as well as individual B1, B 2, G1, G2 aflatoxins and ochratoxin A). We developed a protocol by which we were able to isolate mycotoxins from cereals collected from different regions of Romania. After extraction in chloroform, the mycotoxins were separated by thin-layer

Abstract Miniaturized electrochemical graphite based sensor for the analysis of colchicine, along with its detailed construction was described. The electrochemical behavior of colchicine, both by cyclic and differential pulse voltammetry was investigated, showing an irreversible reduction and oxidation mechanism. The effect of several different electrochemical mediators was studied in order to decrease the oxidation potential of colchicine, but none
