A method for extracting a mycotoxin, when present, from a sample. Compositions and methods include the use of high ionic strength compositions including compositions that include many amine and/or carboxyl groups such as protein based, amino acid based and polyethylene glycol based composition.

The present disclosure discloses a gold/quantum dot nanoprobe for detecting active ricin in a complex matrix and application thereof. The gold/quantum dot nanoprobe is a nanoprobe formed by utilizing gold nanoparticles and quantum dots, which are modified by single strand oligodeoxynucleotides (ssODN), to form double strand oligodeoxynucleotides in a base pairing hybridizing mode and assembling the gold nanoparticles and the quantum dots into a core-satellite structure. According to the present disclosure, the gold/quantum dot nanoprobe is used for detecting the active ricin, has a limit of detection of 7.46 ng/mL, is high in accuracy and good in reliability, and does not require large-scale equipment and complex operations. In order to further eliminate the false positive result, the present disclosure further provides a method for enriching ricin in a complex sample by utilizing magnetic beads. In a case that specific active ricin concentration does not need to be known, the gold/quantum dot nanoprobe provided by the present disclosure can implement naked eye visual detection by the quenched and switch-on operations of fluorescence.
