Ultra-Fast Biosensors and Multi-Photon Microscopy in the Future of Brain Studies

  • Rumiana Bakalova
Article

The direct, highly selective and sensitive real-time imaging of neuro- and biochemical mediators is the only way to clarify precisely the chemistry of the brain and to discover the key molecular targets involved in regulation of brain homeostasis. To realize that, we need: high-speed deep-tissue imaging techniques with high spatial and temporal resolution; and ultra-fast and highly selective molecular sensors, giving a possibility to monitor target molecules directly in their physiological environment; in addition, these molecular sensors have to be comparatively small and permeable for blood-brain barrier, to be applicable in brain studies. The present view accents on the perspectives for development of direct approach for investigation of function/flow coupling phenomenon in the brain, based on the current progress in development of ultra-fast molecular sensors for direct visualization of biochemical mediators (e.g., nitric oxide, Ca ions), and high-speed two-photon/multi-photon deep-tissue imaging.
