Abstract
A device for holding a sample for optical fingerprinting analysis comprises a carrier, and a distribution of non-specific interacting surfaces extending across said carrier. At least one fluidic channel allows a fluid sample to flow through at least a part of said carrier to get in touch with one or more of said non-specific interacting surfaces. One or more optical windows adjacent to said non-specific interacting surfaces enable optical analysis of results of said sample getting in touch with said non-specific interacting surfaces at multiple locations of the carrier.

A device for holding a sample for optical fingerprinting analysis, comprising:
- a carrier;
- a distribution of non-specific interacting surfaces extending across said carrier;
- at least one fluidic channel configured to allow a fluid sample to flow through at least a part of said carrier to get in touch with one or more of said non-specific interacting surfaces;
- and
- one or more optical windows adjacent to said non-specific interacting surfaces for enabling optical analysis of results of said sample getting in touch with said non-specific interacting surfaces at multiple locations of the carrier;
- wherein the device with said fluidic channel and distribution of said interacting surfaces is configured to introduce said fluid sample with at least one interacting surface in a sequential manner so that
- a) at least one first portion of the interacting surface is configured to interact with said sample before at least one other portion of the same interacting surface, and/or
- b) at least one first interacting surface is configured to interact with said sample before at least one other interacting surface.
A method for performing optical fingerprinting analysis of a fluid sample, the method comprising:
- making the sample flow over or through a distribution of non-specific interacting surfaces that extend across a carrier, so that the sample gets in touch with one or more of said non-specific interacting surfaces in a sequential manner so that,
- a) introducing the sample with at least one first portion of the interacting surface to interact with said sample before at least one other portion of the same interacting surface, and/or
- b) introducing the sample with at least one first interacting surface to interact with said sample before at least one other interacting surface;
- directing an excitation signal to multiple locations of said carrier where the sample has got in touch with one or more of said non-specific interacting surfaces;
- collecting and detecting luminescent responses from locations of said carrier subjected to said excitation signal;
- and
- producing a combined set of measurement data indicative of said luminescent responses to characterise said sample.
