Riboswitch sensors to detect clinical biomarkers

This technology is a set of riboswitch sequences tailored to sense creatine, urea, potassium, lithium, and sodium.

Unmet Need: Real-time monitoring of drug elimination for patients with acute kidney injury

Sepsis is the leading cause of acute kidney injury (AKI) in hospitals, resulting in a mortality rate of >60%. A method is needed to appropriately dose medications, including life-saving antibiotics, in patients with renal damage and relatedly highly variable drug clearance rates.

The Technology: Electrochemical aptamer-based sensors to monitor drug elimination

This technology comprises a set of riboswitch aptamer sequences designed to sense creatine, urea, potassium, lithium, and sodium, for use in electrochemical aptamer-based sensors for monitoring drug elimination during continuous renal replacement therapy. This system provides real-time information on extracorporeal clearance, enabling clinicians to make immediate, informed adjustments to antibiotic dosing.

Applications:

  • Monitoring of drug elimination in patients with renal damage
  • Detection of metabolic biomarkers for screening, diagnosis, and monitoring
  • Precision medicine tool to tailor treatments based on individual metabolic profiles
  • Drug screening

Advantages:

  • Real-time drug monitoring
  • Enables rapid, personalized adjustment of antibiotic dosage
  • Multi-target detection of off-target metabolic effects or accumulation of toxic intermediates
