Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Hot-wire anemometers have a very short time-response, which makes them ideal to measure rapidly fluctuating phenomena such as turbulent flows. The purpose of this experiment is to demonstrate the use of hot-wire anemometry.

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

We previously developed a technique for implanting tetrode wires into the central complex of cockroach brains that allows us to monitor activity in individual units of tethered cockroaches. Here we present a modified version of that technique that allows us to also record brain activity in freely moving insects.

FAQs
Electron transfer at the platinum surface links chemical activity to an electrical readout. When oxidation-reduction reactions occur near the wire, the electrode can participate in electron transfer, while an applied potential or measured current changes in response to the surrounding solution. This relationship allows researchers to detect biological or chemical changes during an assay.
Platinum’s chemical stability helps preserve electrode performance in biological and chemical systems. Its resistance to corrosion reduces the likelihood that the wire itself will become a major source of change during an assay. The broad electrochemical operating range further supports reliable measurements across varied, controlled experimental conditions.
When used for sensing, changes at or near the platinum surface are linked to the measured electrochemical response. In a counter-electrode role, the wire supports the electrical arrangement of the assay rather than serving as the primary source of the measured signal. The selected role therefore depends on the assay design and intended readout.
The assay should establish whether the wire functions as the sensing or counter-electrode, identify whether an applied potential or measured current provides the relevant readout, and monitor how the surrounding solution affects that response. In infection and immunology studies, researchers can relate the resulting signal to pathogen-associated molecules, microbial metabolism, or redox-active immune signals.
These assays can monitor pathogen-associated molecules, signals linked to microbial metabolism, and redox-active substances released during immune responses. The electrode does not limit the work to a single type of biological target; instead, its electrical response can be used to follow different solution changes relevant to pathogen detection and host-microbe investigations.
Their resistance to corrosion and broad electrochemical operating range support measurements while biological activity is examined under controlled laboratory conditions. In immunology and infection research, this makes them relevant to biosensors, microbial detection, and studies that track redox-active signals associated with immune responses or cellular activity.
