The Lewis structure of a nitrite anion (NO2−) may actually be drawn in two different ways, distinguished by the locations of the N-O and N=O bonds. If nitrite ions do indeed contain a single and a double bond, the two bond lengths are expected to be different. A double bond between two atoms is shorter (and stronger) than a single bond between the same two atoms. However, experiments show that both N–O bonds in NO2− have the same strength and length, and are identical in all other...

We describe a novel surgical method for catheterizing 'intestinal loops' within the ileum of sheep. Once animals have recovered from surgery and have cleared antibiotics and analgesics, multiple treatments can be deposited directly in loops via the catheters.

Genetic Crosses

To dissect genetic processes or create organisms with novel suites of traits, scientists can perform genetic crosses, or the purposeful mating of two organisms. The recombination of parental genetic material in the offspring allows researchers to deduce the functions, interactions, and locations of genes. This video will examine how genetic crosses were influential in developing Mendel's three laws of inheritance, which form the basis of our understanding of genetics. One genetic crossing...
FAQs
The loops interact electromagnetically when alternating current flows, and the resulting resonance depends on the resonator’s geometry and materials. Adjusting those characteristics changes the frequency at which the system responds most strongly. This tunability lets a designer relate a measured resonant shift to the surrounding biological environment rather than treating the device as a fixed-frequency component.
Field concentration is important because it increases the local interaction between the resonator and nearby biological material. In a Cross-loop Resonator, the coupled loop fields create an oscillating region that can respond to changes close to the device. That localized response supports compact sensing arrangements and can reduce the need for direct electrical connections to the measured target.
Nearby tissue, fluid, or embedded biomaterials can alter the resonant response, producing a shift that serves as the measurement signal. The direction and size of that shift depend on how the surrounding material interacts with the resonating structure, while the baseline response is set by geometry and material choices. Separating these influences is important when interpreting measurements.
First, the resonator’s geometry and materials are chosen to produce a suitable baseline frequency. It is then positioned near the tissue, fluid, or biomaterial of interest, and its resonant response is monitored while the surrounding condition changes. Comparing the observed response with the baseline reveals whether the nearby biological environment has shifted the resonance.
It can support wireless measurements in implantable bioelectronics because sensing does not require direct electrical contact with the nearby target. That feature may simplify integration where wired connections are undesirable or difficult to accommodate. The resonator’s compact form and tunable response also provide a way to monitor environmental changes within a biological setting.
It is relevant when a diagnostic platform must detect changes in tissue, fluid, or embedded biomaterials while preserving measurement flexibility. The device can provide a compact, wireless sensing element whose resonant response changes with the nearby environment. This makes it suited to platforms emphasizing noncontact detection, integration with biological systems, and sensitivity to local material changes.
