Antibody-based sensors for multiplex point-of-care drug monitoringArticleTo improve point-of-care drug detection, scientists developed a multiplex drug monitoring sensor that uses antibodies to bind amphetamine, cocaine, or benzodiazepine1. The binding of these drugs reduces the oxidation current in a concentration dependent manner where higher concentrations of the drug cause a greater decrease in oxidation current. The sensor is selective for these drugs as interferences from analgesics and other illicit drugs had minimal effects on the current change.

Control Line Systems for Lateral Flow AssaysArticleLateral flow tests consist of a test line and a control line. The control line provides validation of a functioning test. If the control line does not appear after running the test, that test is deemed invalid. The choice of a control line antibody will depend on which detector antibody is used in the test.

Lateral Flow Assay Tests for Detecting Drugs of AbuseArticleDrug molecules are small and if directly striped on a membrane, they would “sink” into the sponge-like matrix of the nitrocellulose membrane. Consequently, drug molecules are conjugated to a carrier protein such as Bovine Serum Albumin (BSA) (most common), Bovine thyroglobulin (BTG), and even ovalbumin. The carrier protein part of the conjugate binds to the membrane and exposes the drug for the antibodies to “find”. In most drug tests, the drug BSA conjugate will be on the capture or test line and the antibody to that drug or its metabolites is bound to a detector particle such as gold nanoparticles or colored latex beads.
