Label-free piezoelectric biosensor for prognosis and diagnosis of Systemic Lupus Erythematosus

2017

[EN] An autoantigen piezoelectric sensor to quantify specific circulating autoantibodies in human serum is developed. The sensor consisted on a quartz crystal microbalance with dissipation monitoring (QCM-D) where TRIM21 and TROVE2 autoantigens were covalently immobilized, allowing the selective determination of autoantibodies for diagnosis and prognosis of Systemic Lupus Erythematosus (SLE). The sensitivity of the biosensor, measured as IC50 value, was 1.51 U/mL and 0.32 U/mL, for anti-TRIM21 and anti-TROVE2 circulating autoantibodies, respectively. The sensor is also able to establish a structural interaction fingerprint pattern or profile of circulating autoantibodies, what allows scorin…

Enzyme Inhibition Microassays on Blu-Ray Disks for Drug Discovery

2019

[EN] An enzyme inhibition-based assay for drug discovery developed by microarraing on Blu-ray disks is presented. As a proof-of-concept, the system screens a selected molecule library of potential chemical inhibitors against the glycoenzyme peroxidase, identifying the promising lead compounds with high selectivity using standard Blu-ray disks and drives. In order to face the first drug discovery stages, we establish the bases for a high-throughput screening assay and a methodology based on hypersurfaces suitable to manage a high number of data as well.

Mapping molecular binding by means of conformational dynamics measurements

2017

[EN] Protein-protein interactions are key in virtually all biological processes. The study of these interactions and the interfaces that mediate them play a key role in the understanding of biological function. In particular, the observation of protein¿protein interactions in their dynamic environment is technically difficult. Here two surface analysis techniques, dual polarization interferometry and quartz crystal microbalance with dissipation monitoring, were paired for real-time mapping of the conformational dynamics of protein¿ protein interactions. Our approach monitors this dynamics in real time and in situ, which is a great advancement within technological platforms for drug discover…
