Abstract:
The present invention refers to a method for detecting molecules and/or substances within a sample based on the use of a microcantilever system. The method comprises the variation of a certain condition such as humidity so as the mechanical feature analyzed varies with a characteristic pattern while the target molecule is bound to the detector. The invention also refers to the system used to carry out such method.
Abstract:
The invention relates to the field of biosensors and, more specifically, to nanoparticle biosensors comprising: a magnetic core, a silica layer, one or more outer metal layers which can be of different types and deposited in an alternating manner and immobilized on the outer surface, and a layer of synthetic or natural organic or inorganic biosensor molecules that can bind to biomolecules. The invention also relates to a method of obtaining the nanoparticle biosensors as well as to the different uses thereof.

Abstract:
The invention relates to a method and apparatus for detecting substances or analytes form the analysis of one or several samples. The method comprises mixing the sample with a suitable liquid buffer, homogenizing said sample, adding reagents thereto, filtering it, injecting the sample into the incubation chamber, allowing the sample to react with a biosensor, washing the non-reacted sample excess and detecting the sample retained in the biosensor. The apparatus includes a sample homogenizer module with an ultrasonic piezoelectric device formed by a converter (49) and a horn (16); a sample processing module including a homogenization container (6) and a moving frame (17); a reagent and solution management module including a motorized syringe (60), a reaction module consisting of a support (50) forming a reaction chamber (51) and a data reading module including a laser diode (66) and a CCD camera (67).
