Streaming potential in bio-mimetic microvessels mediated by capillary glycocalyx

Droplet-on-chip electro-spectroscopy detects the ultra-short relaxation time of a dilute polymer solution

“…7 However, in real-life scenarios, the polymer concentration in a solution is usually unknown or may not be accurately known. Interestingly, polymeric solutions are often used as analogues to biofluids 5,15,21 because of some resembling rheological features in a qualitative sense. However, while their flow characteristics can be qualitatively similar, there can be significant quantitative contrast in the relaxation times of these fluids.…”

“…This, in turn, may influence the resulting functionalities of a droplet encapsulation to a rather discernible extent, holding the key in many practical applications, such as inkjet printing, 1 drop deposition, 2 spray atomization, 3 the rapid prototyping of gel-like biocompatible materials, and targeted delivery of drugs mediated by them. 4 The partly viscous and partly elastic nature of such dilute polymer solutions (combined, known as viscoelastic property), as opposed to a completely viscous nature of the solvent, plays an imperative role in orchestrating their intrinsic abilities to adapt to various shapes and sizes, when subjected to a plethora of dynamic conditions ranging from mechanically-imposed stretching to the physiological movement along with the body fluids, 5 hallmarking a wide variety of applications in nature, engineering, and biology.…”

Experimental Study on Electric Signal Response of Liquid in Flexible Tube Under Deformation

“…Steaming potential is an electrical phenomenon caused by the flow of a liquid along a solid surface. [1][2][3][4] When the channel is unchanged, the steaming potential is proportional to the pressure difference of the liquid. [5][6][7] Theoretical studies show that when a liquid is driven by solid deformation, the steaming potential is proportional to the derivative (velocity) of the solid displacement against time.…”
