Abstract: A cartridge for sample preparation includes an inlet configured to receive a collected sample, a phase transfer assembly including a plurality of bead layers, and an outlet. The collected sample is configured to be transferred through the bead layers of the phase transfer assembly to extract a compound therefrom. The outlet is configured to transfer the extracted compound to a detector for analysis of the extracted compound.

Abstract: A system for drug testing includes a collector configured to collect saliva, a processor configured to mate with the collector, and a detector. The collector comprises a mouthpiece, an elongate body, a vent to vent air from the body and a collection portion to collect saliva. The processor is configured to automatically extract a first sample of the saliva and a second sample of the saliva. The detector is configured to mate with the processor and to analyze the first sample to detect an amount of drug in the collected saliva.

Abstract: A high-resolution P?SL system and method incorporating one or more of the following features with a standard P?SL system using a SLM projected digital image to form components in a stereolithographic bath: a far-field superlens for producing sub-diffraction-limited features, multiple spatial light modulators (SLM) to generate spatially-controlled three-dimensional interference holograms with nanoscale features, and the integration of microfluidic components into the resin bath of a P?SL system to fabricate microstructures of different materials.
