In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

An accurate and practical method to measure parameters like strain in myocardial tissue is of great clinical value, since it has been shown, that strain is a more sensitive and earlier marker for contractile dysfunction than the frequently used parameter EF.

Förster Resonance Energy Transfer (FRET)

Förster resonance energy transfer (FRET) is a phenomenon used to investigate close-range biochemical interactions. In FRET, a donor photoluminescent molecule can non-radiatively transfer energy to an acceptor molecule if their respective emission and absorbance spectra overlap. The amount of energy transferred—and consequently the overall emission of sample—depends on the proximity of an acceptor-donor pair of photoluminescent molecules. FRET analysis is combined with other biochemistry...

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...

FAQs
A binding event changes the optical conditions surrounding the photonic structure, often through an alteration in the local refractive index. That change moves the wavelength associated with resonance. Measuring the displacement provides an indirect readout of the interaction without requiring the event itself to be observed visually, making the response useful for monitoring molecular recognition at an engineered surface.
Refractive index serves as a key environmental variable connecting sample composition with the observed optical response. When biomolecular binding or another interaction changes the refractive index near the structure, the resonance wavelength shifts accordingly. Tracking that shift helps relate changes in the sample environment to molecular or material events occurring around the sensing platform.
A time-resolved record shows whether a wavelength displacement develops gradually, occurs during a discrete interaction, or changes as a reaction proceeds. This temporal information can separate a simple endpoint observation from dynamic behavior. In bioengineering, the resulting trace may reveal binding events, reaction dynamics, or evolving sample composition rather than only indicating that a change occurred.
The method can reveal how an engineered surface or material responds when its surrounding optical environment changes. Interactions at the surface may produce measurable resonance displacements, while continued monitoring shows how the response develops. This supports characterization of platforms designed for biosensing and helps connect material behavior with the analytical performance of the resulting device.
A basic workflow establishes the resonance response of an optical or photonic structure, introduces or monitors the relevant sample environment, and records the resonance wavelength as conditions change. The measured displacement is then examined over time and related to the interaction or composition change under study. This sequence supports both event detection and analysis of reaction behavior.
Researchers can use resonance wavelength tracking when they need label-free, real-time information about molecular interactions or changing sample conditions. Applications include evaluating biosensing platforms, monitoring biomolecular binding, and characterizing engineered surfaces or materials. Because wavelength shifts can report binding events and reaction dynamics, the approach also contributes to developing diagnostic devices and other analytical systems.
