Problem
Current CBRN threat detection technologies are limited by requiring specific and energy-intensive methods, often necessitating offsite analysis and being unable to simultaneously detect multiple threat types in-field, leaving onsite personnel vulnerable and requiring complex data analysis.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If highly specific and ultra-sensitive detection methods are used, then detection precision is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent combines multiple detection capabilities (chemical, biological, radiological/nuclear) into a single sensor platform using energy transfer pairs. Multiple specific binding ligands are integrated onto one sensor, allowing simultaneous detection of multiple CBRN threats without requiring separate complex analytical instruments for each threat type.
Solution Approach 2:
The sensor employs a universal detection mechanism (energy transfer) that can detect multiple different threat types through a single platform. The energy transfer pair system serves multiple functions: it detects various CBRN agents, provides signal amplification, and enables field-portable operation, replacing the need for multiple specialized laboratory instruments.
2Measurement precision
If highly specific and ultra-sensitive detection methods are used, then detection precision is improved, but energy consumption increases
Solution Approach 1:
The patent replaces energy-intensive mechanical and electrical systems (mass spectrometry, complex laboratory equipment) with an optical energy transfer mechanism. The FRET/NSET-based detection uses light-induced energy transfer between donor and acceptor molecules, which is significantly more energy-efficient than the high-voltage and complex instrumentation required by traditional ultra-sensitive detection methods.
3Adaptability or versatility
If multiple threat types are detected simultaneously, then adaptability is improved, but device complexity increases
Solution Approach 1:
The sensor divides the detection function into multiple specific binding ligands, each targeting a different CBRN threat type. These segmented ligand components are attached to energy transfer pairs on the sensor platform, allowing each ligand to independently recognize its specific target while sharing the common energy transfer detection mechanism, thus managing complexity through functional segmentation.
Solution Approach 2:
A single sensor platform performs multiple detection functions simultaneously by integrating different specific binding ligands for chemical, biological, and radiological/nuclear threats. The universal energy transfer mechanism handles all detection types, enabling one device to replace multiple specialized sensors and providing comprehensive CBRN detection capability.
4Loss of time
If in-field detection is performed, then response time is improved, but measurement precision may worsen
Solution Approach 1:
The patent replaces complex laboratory analytical systems with a simplified optical energy transfer system that is both field-portable and highly sensitive. The FRET/NSET mechanism provides signal amplification and high detection precision through optical measurements that can be performed with portable equipment, eliminating the need to send samples to centralized laboratories while maintaining ultra-sensitive detection capabilities.
