    Abstract: The disclosure relates to a method for manufacturing a colloidal dispersion of Kraft lignin (KL) nanoparticles, said method comprising the steps of (a) providing KL; (b) dissolving said KL into a solvent, to obtain a solution having a concentration of Kraft lignin of at least 15 mg/ml; and (c) mixing said solution with an antisolvent under mixing conditions, to provide a colloidal dispersion of nanoparticles. Said method is remarkable in that the solvent used in step (b) of dissolving said KL is one or more organic solvents, and in that step (c) of mixing is performed by the addition of the solution of step (b) into an antisolvent being or comprising water. The disclosure also relates to spherical KL nanoparticles with an average diameter size ranging from 9 nm up to 70 nm. The disclosure further relates to various uses of said spherical KL nanoparticle.

    Abstract: A system for incubating one or more cells and/or organotypic cultures for biological investigation, in particular for toxicology assessment, comprising a bio-incubator and a pressure system fluidly connected with the bio-incubator. The pressure system is a cyclic gas pressure system configured for cyclically varying the gas pressure in the bio-incubator between a negative pressure and a positive pressure compared to the atmospheric pressure, so as to reproduce the pressure conditions in lungs of a living mammal. The system is remarkable in that the cyclic gas pressure system comprises a feedthrough with a pipe configured to deviate the air influx from the one or more cells and/or organotypic cultures.

    Abstract: A monitoring process, a user health and/or safety monitoring process, the monitoring process including the steps: providing a sensor set including at least one sensor; obtaining a monitoring configuration from a memory element. The monitoring configuration including: a sensor configuration associated with the sensor set and a body profile associated with a subject body and comprising reference data. The monitoring process further providing, in a memory element, measurement data relating to said subject body, said measurement data being acquired by said sensor set; computing, with computing means, a difference between the measurement data and the reference data; comparing, with comparison means, the difference and a predefined condition; changing, and with changing means, the monitoring configuration depending on the result of the comparing step.
