Singapore-MIT Alliance for Research & Technology

BioSystems and Micromechanics (BioSyM) Inter-Disciplinary Research Group

 
  • BioSyM brings together a multidisciplinary team of faculties and researchers from MIT and the Universities and Research Institutes of Singapore. Our research deals with the development of new technologies to address critical medical and biological questions applicable to a variety of diseases. We aim to provide novel solutions to the healthcare industry and to the broader research infrastructure in Singapore.

  • The guiding tenet of BioSyM is that accelerated progress in biology and medicine will critically depend upon the development of modern analytical methods and tools that provide a deep understanding of the interactions between mechanics and biology at multiple length scales – from molecules to cells to tissues – that impact maintenance or disruption of human health.

BioSyM research published in Lab Chip, 17, 448, (2017):A 3D neurovascular microfluidic model consisting of neurons, astrocytes and cerebral endothelial cells as a blood–brain barrier

BioSym researchers (Giulia, Andrea & Roger) along with collaborators from Duke-NUS report a novel 3D neurovascular microfluidic model consisting of primary rat astrocytes and neurons together with human cerebral microvascular endothelial cells. These three cell types in our neurovascular chip (NVC) show distinct cell type-specific morphological characteristics and functional properties. In particular, morphological and functional analysis of neurons enables quantitative assessment of neuronal responses, while human cerebral endothelial cells form monolayers with size-selective permeability similar to existing in vitro blood–brain barrier (BBB) models.
