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 The needle is withdrawn after a brief pause.

This video demonstrates a method to study protein-drug interactions using QCM biosensor-based biopanning of the T7 phage-displayed peptide library. The biopanning of phages displaying a specific peptide on the QCM biosensor allows specific isolation of high-affinity peptides, followed by amino acid sequencing, which helps to identify specific interaction sites on the target protein.

This protocol is for the isolation of quartz grains by size for luminescence dating of sediments. Outlined are physical cleansing and chemical digestions by soaking sequentially in H2O2, HCl, HF, and HCl again to isolate quartz grains. The quartz purity is quantified with microscopic assessment, Raman spectroscopy, and IR depletion ratio.
FAQs
Fused silica transmits ultraviolet and visible wavelengths more effectively than ordinary glass or many plastics. This allows more of the instrument’s light to pass through the sample rather than being absorbed by the vessel. The improved transmission is especially important when ultraviolet absorbance carries information about nucleic acids, proteins, enzymes, or cell-derived compounds.
The vessel material can contribute optical interference if it absorbs wavelengths used in an experiment. Quartz reduces this problem because its optical clarity supports transmission across ultraviolet and visible regions. As a result, measured absorbance more closely reflects the biological sample, helping researchers evaluate concentration or reaction behavior under controlled measurement conditions.
Quartz is preferable when the measurement uses ultraviolet light or when ultraviolet transmission is otherwise important. Ordinary glass and many plastic cuvettes transmit these wavelengths less effectively, which can interfere with absorbance measurements. For visible-light work, the choice depends on the experimental requirements, but quartz remains useful when broad ultraviolet and visible transmission is needed.
Researchers place biological liquids in the cuvette so a spectrophotometer can measure their absorbance. In bioengineering, the samples may contain nucleic acids, proteins, enzymes, or compounds derived from cells. The resulting optical measurement supports quantitative analysis while the cuvette’s clarity and chemical resistance help maintain controlled conditions during testing.
Measurements made with a quartz cuvette can support concentration quantification and monitoring of reaction kinetics. Concentration analysis helps determine how much of a target biological component is present, while kinetic monitoring follows changes during a reaction. These outcomes make the vessel useful for examining biochemical processes and evaluating cell-derived samples.
Enzyme and other biological reactions can be followed by measuring changes in absorbance over time. Quartz supports this approach when the relevant optical measurements include ultraviolet wavelengths, while its chemical resistance helps maintain the measurement environment. The resulting data can show reaction behavior and provide a basis for assessing controlled biochemical experiments.
