About this Research Topic
Life function in nature has been optimized for a long time thus it is an ideal model system for a new engineering technology development. Biological systems are basically composed of soft matters typically in the form of colloids, emulsions, gels, granules, or liquid crystals. Microscale blood flow is one of the dynamic soft matter physics determined by hematocrit, viscoelasticity, aggregation, deformability, or surface adhesion of red blood cells. By utilizing the structure-property relation of polymeric materials, water, and bubble movement in plants is controlled in smart ways even under such an unfavorable condition as a survival strategy. Fluid/mass transport through porous networks plays a significant role in their performance and is common both in natural and artificial biomimetic systems and one of the important issues for various technology developments including biomedical and energy storage devices. Therefore, the dynamic life function mechanisms can be explained by conventional soft matter physics.
Many scientific issues have been investigated inspired by natural phenomena such as bubble control, water harvesting/phase transition, ion removal/collection, and the like. But the efficiency of an artificial system is generally lower than that of the natural one. Many soft matter objects artificially designed under the controlled conditions have been studied by this point. The nature-inspired microfluidic capillary vessels of similar scale (i.e., size or shape), display higher efficiency than conventional rectangular ones in terms of investigating physiological state and the physical properties of blood. Transport phenomena through porous structures are observed in various systems such as fuel cells and electrolysis. Nonetheless, energy utilizing efficiency of natural systems is much higher. Understanding of flows in porous structures of soft matter could provide novel strategies that would improve the performance of these systems. The interactive mechanism of soft matter with water, ions, or small molecules at varying temperatures and pressure is important for material design and applications. The goal of this Research Topic is the reinvestigation/reinterpretation of the natural systems and increasing the performance by nature-inspired advanced system development.
Biological systems can be systematically investigated in terms of soft matter physics. In addition, natural phenomena can be reproduced by utilizing responsive soft matter. With these two concepts, various technologies can be studied as follows:
• Nature-inspired functional solution, suspension, gel or particles
• Interactive mechanism of materials and biological systems
• Increasing functional efficacy of water and ions
• Transport phenomena in soft matter
• Material design and applications
• Pore network dynamics
• Transport phenomena in porous structures
• Bubble dynamics
• Blood flows under the microfluidic platform
