Automated Reader for High-Throughput Infectious Disease Diagnostics

MARLEX has developed fully functional prototypes for use in Automated Quantum Dot detection applications. Our expertise in high speed fluorescent imaging, real-time embedded control, micro-positioning, laser illumination and low level photonic emission detection has allowed us to rapidly transform a large lab-based experimental proof of concept setup into a working prototype bench top reader.

This reader technology can be scaled to a portable handheld device and is well suited for real-time detection and processing of Quantum Dot Barcodes in Multiplexed High-Throughput Infectious Disease Diagnostics.
