2014
Drop impact of non-Newtonian fluids is a complex process since different physical parameters influence the dynamics over a very short time (less than one tenth of a millisecond). A fast imaging technique is introduced in order to characterize the impact behaviors of different non-Newtonian fluids.

Source: Sweeney, A. M., et al. In Vivo Imaging of Cerebrospinal Fluid Transport through the Intact Mouse Skull using Fluorescence Macroscopy. J. Vis. Exp. (2019)This video demonstrates the process of visualizing cerebrospinal fluid (CSF) flow in a mouse brain using fluorescence imaging. A fluorescent tracer is injected into the cisterna magna (CM), allowing its movement with CSF to be tracked through the subarachnoid and perivascular spaces. Time-lapse imaging captures the tracer's journey,...

This video describes a technique of measuring the interstitial fluid pressure within a tumor by perfusion imaging using an image-guided robotic system. Measurements are compared to the intra-tumoral accumulation of liposomes, within a solid tumor.
FAQs
Thin windows are critical because they must confine the liquid and specimen while still allowing the microscope to record information through the cell. Their electron- or photon-transparent character makes imaging possible without removing the sample from its environment. This design preserves access to liquid-phase structural or chemical changes that vacuum-based observation could disrupt.
Flow, pressure, and applied voltage act as experimental variables rather than incidental conditions. Researchers can control these factors while recording changes inside the sealed cell, allowing dynamic behavior to be associated with a defined environment. In engineering studies, this helps examine how fluid movement, pressure, or electrochemical stimulation influences materials and interfaces over time.
It preserves observation in liquid, whereas conventional vacuum-based imaging can disrupt systems that depend on a fluid environment. The key advantage is not simply seeing a sample at higher detail, but observing change as it occurs under controlled flow, pressure, or voltage. This time-dependent view helps researchers relate transient nanoscale events to evolving material behavior.
An experiment requires a sample suspended in liquid, a sealed fluid cell, thin electron- or photon-transparent windows, and a microscope positioned to record through the cell. The setup may also include controls for flow, pressure, or applied voltage. Together, these components maintain the chosen environment while structural or chemical changes are monitored in real time.
It can support direct observation of nanoparticle growth, corrosion, electrochemical reactions, membrane behavior, and fluid-driven material changes. These applications span particle formation, degradation, interfacial chemistry, membrane responses, and transformations caused by moving liquid. The resulting observations show how processes develop, rather than only documenting a starting and ending state.
By linking nanoscale mechanisms with changes in material structure or chemistry, the method provides evidence relevant to the performance of advanced materials and devices. Observations from fluid-driven changes, corrosion, growth, or electrochemical reactions can help explain why a system behaves as it does under operating conditions. This connection supports more mechanism-based interpretation of engineering designs.
