This video presents synthetic biology and its role in bioengineering. Synthetic biology refers to the methods used to genetically modify organisms in order to make them capable of producing large quantities of a product. This product could be a protein that the cell already makes or a new protein that has been encoded in a newly-inserted DNA sequence. Here, we discuss how an organism's genetic material is modified using transformation or transfection. Then, the process is shown in the...

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 The needle is withdrawn after a brief pause.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
A Synthetic Quartz Cell establishes a defined optical path through the sample. During measurement, the instrument records light transmitted through that sample and compares it with a reference intensity. The resulting absorbance supports quantitative interpretation because measurements made with a defined path length can be related to the sample’s optical response.
Fused silica transmits ultraviolet and visible light strongly, while its chemical stability helps it remain suitable for biological samples. This matters most when measurements target ultraviolet signals, because ordinary glass or plastic cells can absorb light in that region and contribute unwanted optical background. The cell can therefore improve measurement reliability.
Path length gives each measurement a standardized optical distance through the sample. Because absorbance is calculated from transmitted and reference intensities, keeping that distance defined helps make results comparable across biological measurements. This is important for quantitative work with nucleic acids, proteins, and enzyme reactions, where absorbance changes can be interpreted consistently.
Researchers should consider whether the assay uses ultraviolet or visible light and whether the holder must contain a biological or liquid sample. Fused silica is especially useful for ultraviolet measurements because it transmits that light effectively, whereas glass or plastic may absorb it. The selected cell therefore supports the intended spectral range and sample analysis.
The liquid or biological sample is placed in the cell, which provides a defined path for incident light. The instrument measures the intensity that passes through the sample and compares it with a reference intensity. It then calculates absorbance using the Beer-Lambert relationship, producing an optical measurement for biological analysis.
These cells support spectrophotometric analysis of nucleic acids, proteins, enzyme reactions, and other biomolecular samples. Their ultraviolet transmission is valuable when the biological measurement depends on wavelengths that ordinary glass or plastic may absorb. Chemical stability, durability, and low optical background further support quantitative analysis across these different biological applications.
