| 20100219354 | DEVICE FOR MEASURING FLUORESCENT RADIATION ON BIOLOGICAL SUBSTANCES WITH A SEMI-CONDUCTOR SENSOR ARRANGEMENT - The invention relates to a device for measuring fluorescent radiation emitted by biological substances, comprising a light source, a capturing unit, an evaluation unit, at least one emission fibre, and at least one detection fibre. Said emission fibre guides excitation radiation to the biological substrate and the detection fibre receives fluorescent radiation and guides it to the evaluation unit. The capturing unit comprises a semiconductor sensor arrangement that detects fluorescent radiation emitted by the biological substance in wave length areas that are separate from each other, are arranged. Data sets of at least two different reference measurements on at least two different biological substances are stored and compared to the measured measurement values to the stored data sets and issues a result relating to the pathological attacks of the examined biological substances and/or relating to the type of examined, biological substances. | 09-02-2010 |
| 20100258743 | Location Analysis Using Nucleic Acid-Labeled Tags - A method for using information encrypted with a nucleic acid molecule to backtrack an item's path or identify a point of origin. Unique nucleic acid-containing tags are seeded at one or more geographic locations. Using sequence analysis techniques, the person or object of interest is examined for the presence of one or more of the seeded nucleic acids. The geographic location associated with each detected nucleic acid is used to backtrack the item's path or extrapolate a probable point of origin. | 10-14-2010 |
| 20150144806 | TWO-DIRECTIONAL SCANNING FOR LUMINESCENCE MICROSCOPY - In one form, a two-directional scanning method for luminescence microscopy is disclosed. A series of continuous scans are performed by an interrogation wide-field relative to a first direction and a target is identified. A precise position of the target is determined in the first direction. At least one scan by the interrogation wide-field is performed relative to a second direction at or near the precise position of the target in the first direction. The two-directional scanning method produces “on-the-fly” (i.e. ex tempore or impromptu) precise localization of targets. Embodiments open up new applications for background-free or background-reduced luminescence microscopy, for example time-gated or time-resolved luminescence microscopy, in a relatively fast, higher speed or more efficient manner. | 05-28-2015 |
