Abstract: A method for analysing a biological sample with at least one target analyte includes adding to the biological sample at least a first marker and a second marker. The first marker is configured to bind specifically to a first part of the at least one target analyte. The second marker is configured to bind specifically to a second part of the at least one target analyte. The method further includes determining a presence of the target analyte in the biological sample based on detecting the first marker and the second marker in the biological sample.

Abstract: A method for matching a three-dimensional first image of at least one discrete entity with a three-dimensional second image of the at least one discrete entity is provided. The at least one discrete entity includes a biological sample and a plurality of constituent parts of a marker. The method includes: generating a first representation of the marker from the first image; generating a second representation of the marker from the second image; and based upon the representations matching, matching the first image with the second image; or based upon the representations not matching, rejecting the match. Generating the representations includes determining vectors from at least one reference item to at least some of the constituent parts of the marker, determining for the vectors at least one value of a property, and generating the representations of the marker based on a frequency of the at least one value of the property.

Abstract: A marker for analysing a biological sample includes an affinity reagent with a backbone and a barcode oligonucleotide attached to the backbone. The backbone is configured to specifically bind to a target analyte. The marker further includes a label comprising a label oligonucleotide and at least one labelling moiety. The label oligonucleotide and the barcode oligonucleotide of the affinity reagent are configured to hybridise to each other. One of the label oligonucleotide and the barcode oligonucleotide is sensitive to a degradation agent. The other one of the label oligonucleotide and the barcode oligonucleotide is resistant to the degradation agent.

Abstract: A method for marking a biological sample includes providing a biological sample with at least one first target analyte, introducing into the biological sample at least one first nucleic acid backbone, at least one first label configured to attach to the first nucleic acid backbone, and at least one first affinity reagent specific to the first target analyte and configured to attach to the first nucleic acid backbone, and introducing into the biological sample a first plurality of staple strands. Each staple strand of the first plurality of staple strands is configured to hybridise to pairs of folding binding sites of the first nucleic acid backbone, in order to fold the first nucleic acid backbone and generate a compact optically detectable first marker in the biological sample.

Abstract: A method for analyzing a sample is provided. The sample includes a plurality of affinity reagents, at least one of the affinity reagents being attached to an analyte, and a first plurality of combinations of dyes. Each combination of dyes includes at least two dyes having different characteristics for at least one of excitation or emission. Each one of the unique combinations of dyes is attached to an associated affinity reagent of the plurality of affinity reagents according to a first mapping. The method includes directing excitation light at the sample, the excitation light having characteristics for exciting at least one of the at least two dyes having different characteristics, generating at least one first readout from emission light emitted by the excited dyes, and determining, by at least one computer processor, at least one affinity reagent present in the sample based on the at least one first readout.

Abstract: A method for analysing a biological sample includes providing a biological sample with a plurality of target analytes, and introducing a first marker into the biological sample. The first marker includes a first affinity reagent and a first optically detectable label bound to the first affinity reagent. The first affinity reagent is configured to specifically bind to one of the target analytes. The method further includes generating a first optical readout of the biological sample with the first marker, applying the degradation agent to degrade the first affinity reagent, and introducing a second marker into the biological sample. The second marker includes a second affinity reagent and a second optically detectable label bound to the second affinity reagent. The second affinity reagent is configured to specifically bind to one of the target analytes. The method further includes generating a second optical readout of the biological sample with the second marker.
