Caracterização das propriedades mecânicas do tecido cerebral de camundongos usando microscopia de força atômica

Executive Industry Relevance

Quantitative characterization of brain tissue mechanics using atomic force microscopy (AFM) enables biopharma teams to interrogate the physical properties of neurological tissues with high precision. This capability supports early-stage target validation and mechanistic de-risking for CNS drug discovery, where tissue microenvironment and mechanical cues influence disease models and therapeutic hypotheses. Integrating AFM-based measurements enhances predictive confidence in preclinical model selection and portfolio triage for neurotherapeutic programs.
