Abstract: Disclosed is a method for the selection of aptamers that does not require immobilization of the target or the oligonucleotide library. The method includes: (i) combining a selection library of oligonucleotides that contain a random region flanked by primer recognition sites with blocker oligonucleotides that anneal to the primer recognition sites; (ii) exposing the blocked selection library to an immobilization field including random oligonucleotides and removing unbound selection library oligonucleotides; (iii) recovering the selection library oligonucleotides that bound to the immobilization field and combining with a target analyte of interest; (iv) exposing the selection library oligonucleotides-target analyte mixture to an immobilization field; and (v) recovering those selection library oligonucleotides that did not bind to the immobilization field.

Abstract: A method for determining past exposure to chemical agents or heavy metals may include coating a capture material with a capture reagent. The capture reagent may be selected based on an ability of the capture reagent to bind with a target antibody, and the target antibody may be an indicator associated with a particular chemical agent or heavy metal. The method may further include interrogating a clinical sample associated with an individual by forming a mixture of the capture material and the clinical sample, and determining an exposure status of the individual to the particular chemical agent or heavy metal based on whether the capture material demonstrates capture of the indicator.
