The chicken embryo (Gallus gallus domesticus) provides an economical and accessible model for developmental biology research. Chicks develop rapidly and are amenable to genetic and physiological manipulations, allowing researchers to investigate developmental pathways down to the cell and molecular levels. This video review of chick development begins by describing the process of egg fertilization and formation within the chicken reproductive tract. Next, the most commonly used chick staging...

Chicks (Gallus gallus domesticus) are a valuable research tool, not only for studying important concepts in vertebrate development, neuroscience, and tumor biology, but also as an efficient system in which to propagate viruses. Although eggs can be purchased from external suppliers and working with chicks requires very little specialized equipment, an understanding of proper handling procedures is required for normal embryo development. This video will provide an overview of egg handling...

Chick ex ovo Culture

2023
One strength of the chicken (Gallus gallus domesticus) as a model organism for developmental biology is that the embryo develops outside the female and is easily accessible for experimental manipulation. Many techniques allow scientists to examine chicken embryos inside the eggshell (in ovo), but embryonic access can be limited at later stages of development. Fortunately, chicks can also be cultured ex ovo, or outside of the eggshell. The major advantage to ex ovo culture is greater access to...

An Introduction to the Chick: Gallus gallus domesticus

2023
The chicken embryo (Gallus gallus domesticus) is an extremely valuable model organism for research in developmental biology, in part because most of their development takes place within an egg that is incubated outside of the mother. As a result, early developmental stages can be accessed, visualized and manipulated by simply creating a small hole in the eggshell. Since billions of chickens are raised worldwide for meat and egg production, scientists can easily and economically acquire large...

Source: Paolone, G., et al. Personalized Needles for Microinjections in the Rodent Brain. J. Vis. Exp. (2018).This video demonstrates a rodent brain microneedle injection using a quartz microneedle with holes. The microneedle is attached to a syringe and micropump to control the delivery rate. The needle with the injection solution is inserted into the brain with the delivery speed set at low. Once positioned, the delivery speed is increased. The needle is withdrawn after a brief pause.
FAQs
The holding force comes from a pressure difference rather than a mechanical grip. Vacuum ports or channels reduce pressure beneath the workpiece, while atmospheric pressure remains above it and presses the part toward the chuck. The resulting contact can secure a substrate while leaving its active surface unobstructed for processing or inspection.
Quartz provides a flat, chemically resistant surface suited to environments involving heat or aggressive chemicals. Its dimensional stability also supports consistent positioning and contact during precision work. These characteristics help limit contamination concerns and maintain repeatable conditions when the chuck is used for wafer handling, coating, laser processing, or metrology.
The arrangement of vacuum ports or channels influences how evenly the workpiece contacts the chuck. A suitable design can support uniform contact across the substrate and help maintain alignment during processing. In engineering systems, this contributes to more consistent positioning and can improve repeatability when parts must remain stable for inspection or fabrication.
A vacuum chuck secures the workpiece without placing clamps across its surface. This reduces physical obstruction during operations that require access for processing, inspection, or measurement and avoids potential damage associated with direct mechanical clamping. The approach is especially relevant when unobstructed surfaces, low contamination, and precise alignment are important.
A typical workflow places the substrate or component on the chuck’s flat quartz surface, aligns it with the intended processing position, and applies vacuum through the ports or channels. The resulting pressure differential holds the workpiece during the operation. After processing or inspection, releasing the vacuum allows the part to be removed without undoing mechanical clamps.
This approach is useful in wafer handling, photolithography, coating, laser processing, and metrology. These applications can require stable positioning, surface access, low contamination, dimensional stability, or resistance to heat and aggressive chemicals. The chuck’s design supports those requirements by combining unobstructed workpiece access with repeatable contact during manufacturing or inspection.
Integration can improve alignment, uniform contact, and process repeatability. Those outcomes matter when a substrate must remain consistently positioned across manufacturing, inspection, or processing steps. In laboratory and industrial systems, the quartz surface and vacuum workholding arrangement can support controlled handling while reducing reliance on fixtures that obstruct or contact the active part.
