Marking of products to establish identity, source and fate
First Claim
1. A method of marking a liquid, organic, non-aqueous product for identification and then detecting said marked product, said method comprisinga) associating a marker with the product, said marker being inert and non-deleterious with respect to the product and not already associated with the product, said marker being either (i) a print molecule or (ii) a molecularly imprinted, polymeric anti-print molecule which specifically binds to said print molecule, wherein the polymeric anti-print molecule is a synthetic, non-naturally-occurring polymer,b) forming a specific binding complex between said marker and either (i) said molecularly imprinted, polymeric anti-print molecule or (ii) said print molecule, respectively;
- andc) detecting said marked product by detecting said specific binding complex, wherein said detecting is carried out directly in a sample of said product without prior extraction into an aqueous phase.

Abstract
In general, the invention features a method of marking a product for identification in which a marker, composed of a print molecule, print molecule analogue, or molecularly imprinted molecule, are added to the product and subsequently measured in a specific binding assay.

9. A method of monitoring or tracing a liquid organic, non-aqueous process chemical or specialty additive, said method comprising:
-
(a) associating said chemical or said additive with a marker, said marker being inert and non-deleterious with respect to said chemical or additive and not already associated with said chemical or additive, said marker being either (i) a print molecule or (ii) a molecularly imprinted, polymeric anti-print molecule which specifically binds to said print molecule, wherein said polymeric anti-print molecule is a synthetic non-naturally occurring polymer; (b) obtaining a sample from the process or product in which said chemical or additive is employed; (c) forming a specific binding complex between said marker in said sample and said (i) molecularly imprinted, polymeric anti-print molecule or (ii) said print molecule, respectively; and (d) measuring the concentration of said specific binding complex in said sample without extracting said sample into an aqueous phase to monitor or trace said chemical or additive. - View Dependent Claims (10)
