| 20120071335 | Method for Identification, Selection and Analysis of Tumour Cells - The present invention relates to a method for the diagnosis of tumoural conditions and/or of the corresponding state of advance, wherein a specimen of an organic fluid taken from the patient and having a high probability of containing at least one circulating tumour cell (CTC) or a disseminated tumour cell (CTD) is enriched in a population of CTCs or CTDs. According to the invention, at least one type of CTCs or CTDs is isolated by selecting individually single cells in a microfluidic device so to constitute a diagnostic specimen having a purity of at least 90%. On the specimen thus obtained there is subsequently performed a molecular analysis such as to highlight a characteristic thereof suited to enabling diagnosis. | 03-22-2012 |

| 20110050200 | Apparatus and Method for Counting and Identifying Particles of Interest in a Fluid - The invention relates to an apparatus for counting particles in a fluid comprising a substrate having a first surface; a lid having a second surface facing the first; at least one spacer element interposed between the substrate and the lid so as to maintain the first and second surface spaced from one another; a partition with a plurality of through-openings having nanometric size, the partition being interposed between the spacer element and the lid so as to define at least one first chamber between the partition and the lid and at least one second chamber between the partition and the substrate, the chambers being fluidically connected with one another through at least one of the openings. According to the invention, the substrate has at least one first electrode on the first surface and the lid has a second electrode, each first electrode being configured so as to detect an electric signal associated to the passage of one of said particles through one of the through-openings of the partition. The invention further relates to a corresponding method for counting particles in a fluid. | 03-03-2011 |
| 20100331205 | Method and Apparatus for the Identification and Handling of Particles - The present invention refers to the optimised selection and isolation, within a respective population, of elements of interest and/or utility for a series of subsequent operations. The invention concerns a method comprising the phases of: a) identifying, for each particle, at least one of a plurality of characteristic parameters; b) selecting the particles of interest, comparing for each of these the at least one parameter with a respective reference parameter. It furthermore comprises the phases of c) storing, for each of said particles, the at least one parameter identified; d) processing the value of a function of said stored parameter, associating the function with a criterion for selection of the particles of interest chosen from a group of possible selection criteria; e) establishing for each particle a threshold criterion to be used as reference parameter. The threshold criterion is established on a time by time basis according to the result of the above processing. | 12-30-2010 |
