| Various technologies for measurement of properties of a particulate suspended in a gas phase via laser-induced incandescence (LII) are described herein. A beam of light can be emitted into a multi-pass optical cell using a laser. The multi-pass optical cell comprises a system of one or more mirrors that repeatedly reflects the beam through a measurement region, stimulating incandescence of particulates present in the measurement region. An LII detection system having a field of view that encompasses the measurement region then receives blackbody or quasi-blackbody radiation emitted by the incandescing particles and outputs data indicative of one or more properties of the particulates in the measurement region. | ||||||

| Methods, apparatuses, and computer program products are provided where fluid, such as a blood sample, is entered into a microfluidic channel in a microchip where the microfluidic channel possesses a micro/nanopillar array for sorting molecules by size. When the fluid passes through the micro/nanopillar array it is separated into particles of interest or particles not of interest or both. When particles of interest are lit by a light source via a first waveguide in the microchip connecting the light source to the microfluidic channel, then lighted particles of interest can be detected by an optical detector via a second waveguide in the microchip connecting the optical detector to the microfluidic channel. The information from the optical detector can be analyzed further by connecting the microchip to a mobile computing device with its own processing abilities or abilities via the internet or cloud. | ||||||

| The invention relates to a method for determining the average radius of gyration (rg) of particles with a size of ≤1 μm in a suspension, and to a device for carrying out the method according to the invention. The method is based on the scattering of linearly polarised electromagnetic radiation on nanoparticles, which, suspended in a solution, are moved through a through-flow cell. The irradiation is carried out perpendicular to the movement direction, wherein the scattering intensity is measured via at least four detectors that are arranged in a defined plane at defined angles. Alternatively, at least one mirror can be used in the position of at least one of the detectors, which deflects the radiation to at least one detector. Based on the scattering intensities, both the average radius of gyration (rg) of the particles as well as the concentration thereof in the suspension can be determined. | ||||||
