Abstract: Described is a system and method for detecting whether a biological event has occurred in a cellular sample, and then activating a fluidics system to fix the cell at the point in time with the event occurred. In one example, a sample preparation system includes a camera linked to a confocal microscope that is interrogating a cellular sample. Once a detectable event, such as a binding event, has occurred, the sample preparation system releases a fixative to fix the cell at the point in time when the event was detected.

Abstract: The invention relates to a method, a device and a system for the treatment of biological frozen samples using plasma focused ion beams (FIB). The samples can then be used for mass spectrometry (MS), genomics, such as gene sequencing analysis or next generation sequencing (NGS) analysis, and proteomics. The present invention particularly relates to a method of treatment of at least one biological sample. This method is particularly used for high performance microscopy, proteomics analytics, sequencing, such as NGS etc. According to the present invention the method comprises the steps of providing at least one biological sample in frozen form. The milling treats at least one part of the sample by a plasma ion beam comprising at least one of an O+ and/or a Xe+ plasma.

Abstract: A method of imaging a specimen comprises directing a beam to irradiate a specimen; detecting radiation emanating from the specimen; scanning the beam along a path; for each sample point in said path, recording a measurement set M={(Dn, Pn)}, where Dn is the detector output as a function of value Pn of measurement parameter P; deconvolving M and spatially resolving it into a set representing depth-resolved imagery of the specimen, whereby, at point pi within the specimen, in a first probing session, irradiating, in a first beam configuration, pi with Point Spread Function F1, whereby said beam configuration is different to P; in at least a second probing session, irradiating, in a second beam configuration, pi with Point Spread Function F2 which overlaps partially with F1 in a zone Oi in which pi is located; sing an Independent Component Analysis algorithm to perform spatial resolution in Oi.

Abstract: A method of accumulating an image of a specimen using a scanning-type microscope, comprising the following steps: Directing a beam of radiation from a source through an illuminator so as to irradiate a surface S of the specimen; Using a detector to detect a flux of radiation emanating from the specimen in response to said irradiation; Causing said beam to follow a scan path relative to said surface; For each of a set of sample points in said scan path, recording an output Dn of the detector as a function of a value Pn of a selected measurement parameter P, thus compiling a measurement set M={(Dn, Pn)}, where n is a member of an integer sequence; Using computer processing apparatus to automatically deconvolve the measurement set M and spatially resolve it so as to produce reconstructed imagery of the specimen, wherein, considered at a given point pi within the specimen, the method comprises the following steps: In a first probing session, employing a first beam configuration B1 to irradiate the point pi with an associated first Point Spread Function F1, whereby said beam configuration is different to said measurement parameter; In at least a second probing session, employing a second beam configuration B2 to irradiate the point pi with an associated second Point Spread Function F2, whereby: F2 overlaps partially with F1 in a common overlap zone Oi in which point pi is located; F1 and F2 have respective non-overlapping zones F1′ and F2′ outside of Oi, Using a Source Separation algorithm in said computer processing apparatus to perform image reconstruction in said overlap zone Oi considered separately from said non-overlapping zones F1′ and F2′.
