Abstract:
1. A method for lifting prints, detecting one or more analytes, drug residues, or contaminants in a mixture, or any combinations thereof comprising the steps of: placing a substrate or a film on top of and in contact with the print, the one or more analytes, drug residues, or contaminants in a mixture, or any combinations thereof, wherein the substrate or film comprises a metal coated surface; applying a voltage to the substrate or the film, wherein the application of the voltage results in a lifting, a retrieval or an adhesion of the print, the one or more analytes, drug residues, contaminants in a mixture, or any combinations thereof due to a combination of electrostatic and conductive forces; and providing an extraction system for an extraction of the one or more analytes from the substrate followed by a transfer to a detection system, wherein the detection system is coupled to the extraction system, wherein the extraction system comprises: a workstation comprising a plurality of moveable nanopositioners, wherein the nanopositioners are capable of movement in a X direction and in a Y direction and in a Z direction with respect to the substrate, wherein the nanopositioners hold one or more probes, grippers, capillary tips or any other suitable accessory including multiple capillaries each of which is capable of delivering solvent to the substrate and extracting and transferring a liquid phase and the nanopositioners permit detection of analytes at the molecular, cellular or subcellular level.
