The invention relates to a method for preparing a substrate comprising a sample reception area and a sensing area. The method comprises the steps of: 1) applying a sample on the sample reception area; 2) rotating the substrate around a predetermined axis; 3) during rotation, at least part of the liquid travels from the sample reception area to the sensing area due to capillary forces acting between the liquid and the substrate; and 4) removing the wave of particles and liquid formed at one end of the substrate. The sensing area is closer to the predetermined axis than the sample reception area. The sample comprises a liquid part and particles suspended therein.

Method for preparing a substrate by applying a sample to be analysed

A rotatable platform is provided for use in Lab-on-disc (LoD) applications. A LoD microfluidic device has the rotatable platform and is suitable for analysis of a fluid sample. Real-time monitoring of cells is also provided, using a centrifugal microfluidic platform. A mobile LoD device is provided, which can be used in remote destinations and for point of care applications. A method for monitoring microorganisms under the constant supply of nutrients includes the step of inoculating the cells in a culture chamber in a rotatable microfluidic platform, rotating the platform such that liquid in a reservoir connected to or located on the platform, the liquid comprising nutrients for the cells, is constantly supplied to the cells in the culture chamber by means of shear/centrifugal force resulting from rotating the platform, and continuously monitoring the cells during rotation of the platform by means of imaging, electrochemical and/or electrical measurements.

An apparatus for carrying out Raman spectroscopy on a sample includes a light source for providing a beam of excitation radiation, and an optical system including a spectrograph. The spectrograph includes a grating that divides a beam of scattered light into a spectrum of spatially separated wavelength components and to direct a portion of the spectrum to a detector. The spectrograph includes: 1) a first lens system for focusing the portion of the spectrum onto the detector and 2) a second lens system-configured to provide a focal plane with focal point in the optical path for focusing the beam of excitation radiation and/or the beam of scattered radiation at the focal point. The apparatus including a reference sample arranged in the focal plane, in particular at the focal point, for obtaining a reference spectrum from the reference sample.

The present invention relates to a multisensor array for detection of analytes in the gas phase or in the liquid phase, comprising at least two different chemo-selective compounds represented by the general formula (I) wherein the hetero atoms X-Xand the substituents R-Rare defined in the specification and the dashed bonds represent independently of each other either a single bond or a double bond. Said chemo-selective compounds are capable of individually changing physicochemical properties when exposed to analytes or analyte mixtures and these changes can be detected by a transducer or an array of transducers. The present invention does also relate to the use of at least two different chemo-selective compounds in a sensor array, a method for preparation of such sensor arrays and the use of said sensor arrays. Furthermore the present invention relates to methods for detecting and identifying analytes or mixtures thereof in the gas phase or in the liquid phase.

The present invention relates to methods and devices for determining the weight of small particles, typically being nano-sized particles by use of resonating fibers in the form of elongate members being driven into resonance by an actuator or e.g. thermal noise/fluctuation. The frequency shift in resonance frequency due to depositing of nano-sized particles is correlated with the mass deposited on the elongate member and the vibration frequency of the elongate member is determined by a detector. The read-out from the detector is transformed into a mass deposited on the elongate member. Particles are deposited by letting a fluid with the particles flow past the elongate member.

Resonant fiber based aerosol particle sensor and method

A substrate primarily for SERS determination, the substrate has a number of elongate elements with a density of at least 1&#xd7;10elongate elements per cmand having metal coated tips. When the elements may be made to lean toward each other, such as by providing a drop of a liquid thereon and allowing the liquid to dry, groups of tips of elongate elements are formed and the Raman enhancement is extremely high.
