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 The needle is withdrawn after a brief pause.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 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
The silicon–oxygen network gives quartz support strong thermal stability and low chemical reactivity. As a result, the substrate can remain reliable during high-temperature experiments and in environments where reactive materials might degrade or interact with their container. This stability helps preserve the original sample or catalyst condition, making measured chemical behavior less likely to reflect support-related changes.
Surface silanol groups provide chemically accessible sites that can interact with molecules at the quartz surface. These interactions may promote adsorption or allow chemical species to be attached to the substrate. Their presence therefore makes quartz more than an inert holder: it can also influence how samples, catalysts, or reactive materials are positioned and retained during analysis.
Low reactivity helps prevent the support from becoming an unintended participant in the experiment. When the substrate interacts only weakly with the sample or reaction environment, observed results more closely represent the chemistry under investigation. This property is especially valuable when maintaining sample integrity, limiting contamination, or distinguishing catalyst behavior from effects caused by the supporting material.
Optical transparency allows analytical observations to be made through or around the substrate without relying on an opaque support. At the same time, surface interactions can be controlled through adsorption or attachment at silanol-containing sites. Combining these features helps researchers examine reactive materials while maintaining a defined interface, which can improve the reliability of spectroscopic or surface-sensitive measurements.
Quartz support is particularly useful when an experiment combines elevated temperature with a need to preserve sample composition and minimize contamination. Its thermal stability and chemical resistance allow catalysts or reactive materials to remain held in place under demanding conditions. This makes it relevant to reaction systems in which support degradation could otherwise complicate interpretation or reduce experimental performance.
In spectroscopy, quartz can provide a transparent, stable substrate for examining samples. In chromatography, its chemical resistance supports handling materials without readily introducing reactive contamination. Catalytic studies use it to hold catalysts while maintaining suitable thermal and surface conditions. Across these applications, the support contributes to more dependable measurements by combining durability with controlled interactions at the sample interface.
Suitability depends on the experiment's temperature, chemical environment, measurement method, and desired surface behavior. Quartz is advantageous when thermal stability, low reactivity, optical transparency, or adsorption sites are important. Researchers should also consider whether silanol-mediated interactions could affect the sample. Matching these properties to the analytical objective helps preserve sample integrity and supports meaningful results.
A stable quartz substrate can reduce changes that originate from the container rather than from the catalyst or sample itself. Its resistance to heat and chemical attack helps maintain the experimental setting, while controlled surface interactions can keep materials associated with the support. Consequently, measurements may provide a clearer indication of intrinsic chemical behavior and reduce uncertainty caused by contamination or substrate instability.
