background

● Development of bio-sensing technology.
● Drawbacks in conventional bio-imaging technology : Seamless imaging from cells to tissues; Stable fixation of probes on the surface of biological tissue; Vibration control of monitored objects.

summary

● Luminescence sensor made from free-standing polymer nanosheets with the thickness of tens to hundreds of nanometers.
● Versatile fabrication by selecting sensor dyes (e.g.,temperature, oxygen concentration).
● Ratiometric sensing of biological information.

predominance

● To be stuck on biological tissues w/o glue fixation.
● High spatiotemporal resolution by ultra-thin structure.
● Wide-mapping range from a few cells to tissue size.

application/development

● Sticky sensor (High-spatiotemporal resolution, disposable).
● Sensors for extreme environment, surgical situation, etc.

material

  • Ratiometric-luminescence sensor with bilayered structure (Ref: ACS Appl. Mater. Interfaces, DOI: 10.1021/acsami.6b06075)
  • Temperature mapping of living biological tissues (e.g., dorsal muscle of a beetle).
  • Temperature sensitivity and spatial resolution of nanosheet sensor
