Source: Tamara M. Powers, Department of Chemistry, Texas A&M University The glovebox provides a straightforward means to handle air- and moisture-sensitive solids and liquids. The glovebox is what it sounds like: a box with gloves attached to one or more sides, which allows the user to perform manipulations within the glovebox under an inert atmosphere. For manipulations under inert atmospheres, chemists can choose between Schlenk or high-vacuum techniques and a glovebox. Schlenk and...

We describe an electrochemical sensor assay method for rapid bacterial detection and identification. The assay involves a sensor array functionalized with DNA oligonucleotide capture probes for ribosomal RNA (rRNA) species-specific sequences. Sandwich hybridization of target rRNA with the capture probe and a horseradish peroxidase-linked DNA oligonucleotide detector probe produces a measurable amperometric current.

This article will demonstrate how to monitor glutamine dynamics in live cells using FRET. Genetically encoded sensors allow real-time monitoring of biological molecules at a subcellular resolution. Experimental design, technical details of the experimental settings, and considerations for post-experimental analyses will be discussed for genetically encoded glutamine sensors.

Source: Jakobs, M., et al. Subcutaneous Trigeminal Nerve Field Stimulation for Refractory Facial Pain. J. Vis. Exp. (2017)This procedure demonstrates the implantation of subcutaneous electrodes for trigeminal nerve stimulation to treat neuropathic facial pain. The electrodes are tunneled subcutaneously from the affected facial region to an infraclavicular pocket, where they are connected to an internal pulse generator (IPG). The IPG delivers electrical stimulation, activating mechanoreceptor...
FAQs
The sensing element interacts with a selected biological or physical target, such as pressure, temperature, an electrical signal, or a biochemical analyte. That interaction changes a measurable property, which the device converts into an electrical or optical output. The resulting signal can then be recorded and transmitted, allowing biological changes to be followed over time.
The monitored target depends on the biological question and the sensing element. Subcutaneous sensors may respond to physical variables, including pressure or temperature, as well as electrical signals and biochemical analytes. This range allows one device type to support different investigations, from physiological signaling to chemical changes associated with metabolism or disease.
Continuous measurement produces time-resolved data rather than isolated observations from repeated external sampling. This makes it possible to examine how a biological signal or chemical change develops, fluctuates, or responds over time. In biology, that temporal information can improve the study of dynamic physiology, disease progression, metabolism, and responses to treatment.
Signal transduction links the target being measured with the data ultimately analyzed by researchers. After the sensing element interacts with pressure, temperature, an electrical signal, or a biochemical analyte, the device expresses that interaction as an electrical or optical output. Without this conversion step, the underlying biological change could not be readily recorded or transmitted.
A study places the device beneath the skin, positions its sensing element to interact with the selected target, and collects the resulting electrical or optical output. The signal may then be recorded and transmitted for analysis. This workflow supports repeated observation of the same biological process over time without requiring continual external sampling.
Researchers may choose this approach when they need to follow physiology, metabolism, disease progression, or treatment responses over time. Its value is greatest when isolated measurements would miss changes between sampling points. By collecting time-resolved information from beneath the skin, the method can reveal patterns in biological processes as they develop.
Data from these devices can help characterize changing physiological signals and chemical conditions within the body. Researchers can use the measurements to examine dynamic biological processes, track disease-related changes, and assess responses to treatment. In biomedical research, such information may also inform personalized monitoring strategies by providing observations that reflect an individual’s changing state over time.
