Bio-affinity Based Sensing Concept for Toxic Substances

The need for rapid and reliable detection of highly toxic substances, such as illicit drugs and organophosphorus compounds, is becoming increasingly critical for the safety of law enforcement, first responders, military personnel, and the general public.
Current methods for detecting exposure to these substances rely on invasive blood or urine samples, which are not suitable for field use. The Halámek Research Group at Middle Tennessee State University is focused on advancing biosensing technologies designed for toxicology, forensics, and homeland security applications.
Traditional toxicology testing usually requires invasive sampling and laboratory analysis, both of which are resource-intensive and prone to false negatives as samples degrade over time. In contrast, the Halámek Research Group is focused on developing portable, rapid, and user-friendly sensing technologies that deliver reliable results directly at the point of need, eliminating the reliance on complex laboratory processes for sample screening.
The Halámek Research Group focuses on developing nonconventional sampling methods that utilize alternative biological matrices and innovative detection strategies to identify toxic compounds, particularly for use by law enforcement and first responders. These novel detection approaches are being developed through a variety of biochemical assays, which can be integrated with optical readout platforms and provide simple visual colorimetric feedback. The goal is not only to enhance the speed and accuracy of substance detection but also to broaden the potential for where and how toxic substances can be efficiently collected and analyzed. By advancing these unconventional biosensing techniques, the laboratory aims to contribute to safer communities and more effective public health responses.
