1 results about "Acute thrombosis" patented technology

An immunosensor device is disclosed for rapid detection of circulating biomarkers associated with thrombosis, including C-reactive protein (CRP), calprotectin, soluble platelet selectin (sP-selectin), and D-dimer. The immunosensors were fabricated using fiber-laser engraving of carbon nanotubes and CO2-laser cutting of microfluidic channels and features, along with the electrochemical deposition of gold nanoparticles to conjugate with biomarker-specific aptamers and antibody. Using unsupervised clustering based on 4-biomarker concentrations, thrombotic events were predicted in 49 of 53 patients. The 4-biomarker combination yielded an area under the receiver operating characteristic curve (AUC) of 0.95, demonstrating high sensitivity and specificity for acute thrombosis prediction compared to the AUC values for individual biomarker: CRP (0.773), calprotectin (0.711), sP-selectin (0.683), and D-dimer (0.739). The immunosensor device with unsupervised clustering provides accurate and efficient methods for predicting thrombosis, guiding personalized medicine.
