About NextGen-O2k
- Oroboros - as a driving force in mitochondrial physiology - extends the analytical and diagnostic power of high-resolution respirometry by integration of NADH- and Q-redox monitoring in the NextGen-O2k. We aim at establishing the Oroboros quality control management for dissemination to our worldwide O2k-Network laboratories. This will become an effective contribution to address the acute reproducibility crisis of scientific investigation. In the spirit of Open Science and global networking, we will enable data sharing across projects and institutions in an Open Access database on mitochondrial physiology and pathology, to resolve the inflation crisis and ultimately the value-impact crisis of present academic publication. This will support key developments in mitochondrial medicine. In addition, we expand our business to algal biotechnology and ecology with the photobiology module of the NextGen-O2k, widening our focus from medicine to environment and climate.

Aims
- Form the O2k to the NextGen-O2k
- Between 1992 and 1994, Oroboros Instruments released its core technology for high-resolution respirometry (HRR), the Oxygraph-2k or O2k, for real-time monitoring of oxygen consumption of mitochondria, tissues, and living cells. Dissolved oxygen is measured using high-resolution polarographic oxygen sensors. Its main advantages are the unique signal stability and resolution of oxygen. HRR is the core technology present in every single of the devices and it will remain the basis of the NextGen-O2k.
- In 2012, the updated version of the O2k was launched, the O2k-FluoRespirometer. The integrated Smart Fluo-Sensors combine fluorescence excitation and detection of defined wavelengths that in combination with fluorophores allow for the measurement of additional mitochondrial parameters, such as membrane potential, H2O2 production, calcium concentration, and ATP production.
- The unique software DatLab has been developed for data acquisition and analysis. DatLab allows the researcher to perform calibrations (including automatic barometric and temperature adjustments), background correction, experimental SUIT (substrate-uncoupler-inhibitor-titration) protocols and data analysis.
- With the O2k core technology, developed exclusively by Oroboros for high-resolution measurement of oxygen flux, the NextGen-O2k was developed.

|---|---|---|
| Chlororespiration | Chlororespiration is the phenomenon by which oxygen is consumed by a putative respiratory electron transfer chain (ETC) within the thylakoid membrane of the chloroplasts and ATP is produced. It is a process that involves the interaction with the photosynthetic ETC in which the NAD(P)H dehydrogenase enzyme transfers electrons to oxygen molecules with the assistance of the photosynthetic Plastoquinone (PQ), which acts as a non-photochemical redox carrier. Initially described in the unicellular alga Chlamydomonas reindhartdii, chlororespiration was highly disputed for years until the discovery of a NAD(P)H-dehydrogenase (Ndh) complex (plastidic encoded) and plastid terminal oxidase (PTOX) (nuclear encoded) in higher-plant chloroplasts. The PTOX, which is homologous to the plant mitochondrial alternative oxidase, has the role of preventing the over-reduction of the PQ pool while the Ndh complexes provide a gateway for the electrons to form the ETC and consume oxygen. As a result of this process there is a cyclic electron flow around the Photosystem I (PSI) that has been reported to be activated under stress conditions acting as a photoprotection mechanism and could be involved in protecting against any other stress that implies the increase of ROS formation. | |

| Mitochondrial membrane potential | mtMP, Δψ [V] | The mitochondrial membrane potential, mtMP, is the electric part of the protonmotive force, ΔpH+.
Δψ = ΔpH+ - ΔµH+ / F mtMP or Δψ is the potential difference across the inner mitochondrial (mt) membrane, expressed in the electric unit of volt [V]. Electric force of the mitochondrial membrane potential is the electric energy change per ‘motive’ electron or per electron moved across the transmembrane potential difference, with the number of ‘motive’ electrons expressed in the unit coulomb [C]. |

| Oxygen kinetics | Oxygen kinetics describes the dependence of respiration of isolated mitochondria or cells on oxygen partial pressure. Frequently, a strictly hyperbolic kinetics is observed, with two parameters, the oxygen pressure at half-maximum flux, p50, and maximum flux, Jmax. The p50 is in the range of 0.2 to 0.8 kPa for cytochrome c oxidase, isolated mitochondria and small cells, strongly dependent on Jmax and coupling state. | |
| PhotoBiology | PB | PhotoBiology is the scientific study of the beneficial or harmful effects of light, understood as non-ionizing radiation (i.e. ultraviolet, visible and infrared radiation) on living organisms. It includes topics such as the study of photosynthesis, photochemistry, photophysics, photomorphogenesis, vision, bioluminescence, circadian rhythms and photodynamic therapy. Non-ionizing (or non-ionising) radiation is any type of electromagnetic radiation that does not carry enough energy per quantum (photon energy below 10 eV) to completely remove an electron from an atom or molecule. When photons contact molecules, the molecules can absorb the photon energy and become excited, reacting with surrounding molecules and stimulating "photochemical" and "photophysical" changes. |
| Photosynthesis | PS | Photosynthesis is the process used by plants and other organisms that converts light (mostly solar) energy into chemical energy which is subsequently released to fuel organisms' activities. It has two phases: the light-dependent phase and the light-independent (dark) phase. In plants, algae, and cynobacteria, light energy is absorbed during the light phase by the pigment called Chlorophyll and used to split water and generate short-term stores of chemical energy - adenosine triphosphate (ATP), and reducing power - nicotinamide adenine dinucleotide phosphate (NADPH), with the net production of O2 gas as a waste product. And during the dark phase this chemical energy and reducing power are used to synthesize organic matter from the atmospheric CO2 in the form of carbohydrates or sugars through the metabolic pathway called Calvin cycle. The whole process is what is called oxygenic photosynthesis and is responsible for producing and maintaining the oxygen concentration of the Earth’s atmosphere. In bacteria such as the cyanobacteria photosynthesis involves the plasma membrane and the cytoplasm, and in Eukaryotic cells (plants and algae) photosynthesis takes place inside organelles called chloroplasts. |
