Chemical Approaches to Carbon Capture and Release – Inspiration from Natural Solutions to Gas Exchange The Big Picture: We are learning how natural systems have achieved such elegant and efficient gas exchange systems for both the molecular and the micron scale. Covers several applications including laser manipulation and dissection, bio-imaging, flow-cytometry and biosensors, optical biopsy and spectroscopy. How do biological systems makes use of the principles of solubility to support life? Biological systems need water for diffusion, active transport, cohesion, adhesion, and also because water. Kenneth Heller. Why is pH important in. Hypertonic, isotonic, and hypotonic solutions and their effect on cells.
