Research methods

Here are some of the various methods Water&Light uses, among others, for the studies we do.

For ultraweak photon emission measurements in agriculture, spontaneous photon emission and delayed luminescence techniques are used.

Spontaneous photon emission is mainly applied to estimate the defense system of plants, such as the quality of the defense system of plants, the degree of protection against attacks by pathogens such as bacteria, fungi and insects.

Delayed luminescence provides information about the vitality of a biological product. It is based on structural quality in relation to the development stage of the product. Vitality is a new quality marker of food products and complementary to commonly used tests for chemical content and structural properties of a product.

Delayed luminescence is used to:

Predict the germination rate of seeds,

estimate growth and maturation stages,

and predict vitality under different storage conditions.

Measurements of urine and blood from animals and humans with UV, VIS, NIR and Raman spectroscopy

In addition to spectroscopy, at Water&Light we also measure human photon emissions. Photon phenomena are investigated from the cellular level to the level of an individual organism. The development of highly sensitive photon detection techniques is being followed closely. The studies demonstrate the potential utility of ultraweak photon emission for detecting relevant biomedical information for diagnosing pathophysiological conditions from the system.

In addition to photon measurements, we can also measure EEG, ECG and respiratory signals.

We have experience with different types of sensors, such as photomultiplier tubes (PMT), photodiodes and spectrometers.

We can design and build prototypes to your specifications:

You can specify the type of sensor (photomultiplier tube (PMT), photodiode or spectrometer).
You can specify the shape and size of the sample chamber or holder needed for your application.
You can specify the light source for sample exposure.
You can specify the control software.

We design to your specifications and deliver the system.

We can provide both hardware and software.
