Nós apresentamos dois independentes, microscópio de ferramentas baseadas em medir as deformações induzidas nucleares e citoesqueleto em single, vivendo células aderentes em resposta à aplicação de tensão global ou localizada. Estas técnicas são utilizadas para determinar a rigidez nuclear (ou seja, deformabilidade) e para transmissão de força sonda intracelular entre o núcleo e citoesqueleto.
