This 3D microfluidic printing technology prints arrays of cells onto submerged surfaces. We describe how arrays of cells are delivered microfluidically in 3D flow cells onto submerged surfaces. By printing onto submerged surfaces, cell microarrays were produced that allow for drug screening and cytotoxicity assessment in a multitude of areas.

Buoyancy and Stability for Submerged and Floating Bodies
0 Views •
2025
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

FAQs
Continuous perfusion supplies the immersed acute brain slice with oxygenated artificial cerebrospinal fluid throughout the experiment. This environment helps preserve cellular function while allowing researchers to maintain controlled recording conditions. Because the solution is continuously renewed, investigators can examine neural responses while adjusting experimental variables, including stimulation or pharmacological manipulation, to evaluate their effects on activity.
Membrane-potential recordings show changes in a neuron’s electrical state, whereas synaptic-current measurements focus on currents associated with synaptic transmission. Extracellular signals provide activity recorded outside individual cells. Selecting among these signal types allows researchers to examine neuronal excitability, synaptic communication, or broader circuit responses within the same ex vivo experimental framework.
Controlled stimulation tests how neural tissue responds to defined inputs, while pharmacological manipulation changes selected experimental conditions to reveal their effects on activity. Recording the resulting membrane potentials, synaptic currents, or extracellular signals helps connect cellular responses with circuit-level behavior. This approach supports investigation of mechanisms underlying excitability, synaptic transmission, and network responses.
Researchers maintain an acute brain slice fully immersed in continuously perfused, oxygenated artificial cerebrospinal fluid. They then position microelectrodes to measure membrane potentials, synaptic currents, or extracellular signals. After establishing the recording, investigators can apply stimulation or pharmacological manipulation and compare the resulting neural activity under the controlled conditions provided by the submerged chamber.
This technique is useful when researchers need to examine neural activity while controlling the surrounding experimental conditions precisely. It can support studies of normal brain physiology, disease processes, and potential therapeutics. By measuring cellular and circuit responses in living brain tissue maintained ex vivo, investigators can evaluate how specific manipulations influence neuronal excitability and synaptic transmission.
Recorded activity can indicate how neurons respond electrically, how synaptic transmission changes, and how neural circuits react to stimulation or pharmacological manipulation. These outcomes help researchers relate cellular mechanisms to network function. The resulting measurements can therefore provide evidence about brain physiology, disease-related changes, or the effects of experimental interventions relevant to therapeutic research.
