milk powder fluorescent powder for fingerprints

Sensors | Free Full-Text | A Novel Graphene Oxide-Based ...- milk powder fluorescent powder for fingerprints ,In this paper, a rapid and sensitive fluorescent aptasensor for the detection of aflatoxin M1 (AFM1) in milk powder was developed. Graphene oxide (GO) was employed to quench the fluorescence of a carboxyfluorescein-labelled aptamer and protect the aptamer from nuclease cleavage. Upon the addition of AFM1, the formation of an AFM1/aptamer complex resulted in the aptamer detaching from the ...Casein - Natural PigmentsCasein or milk powder is used as a binder for making milk paint and glue. Available in packages of 100 gram, 500 gram, and 1 kilogram bags. Casein makes an all natural, non-toxic, zero VOCs artistic medium and adhesive. Use it alone or mix with natural pigments. See casein paint recipes below.
