BIOSENSORS, AND METHOD AND KITS FOR USING SAME

摘要

A stabilised thylakoid membrane formulation comprising thylakoid membranes in a buffered solution and liposomes, wherein the formulation has a ratio of chlorophyll/liposomes of at least about 10:1. The invention further comprises a method for detecting or quantifying the presence of toxic molecules in a fluid sample, comprising obtaining a stabilised thylakoids membranes formulation; and assessing the photosynthetic efficiency of the thylakoid membranes formulation in the presence of said sample, whereby the molecules are detected when the photosynthetic efficiency is measurably different in the presence versus in the absence of the sample. The present invention also comprises kits using the stabilised thylakoid membranes formulation for detecting and/or quantifying the toxic molecule in a fluid sample.
