Abstract

Official abstract text for this publication.

Method for detecting an analyte of interest in a sample. The method can include providing a container comprising a microstructured surface, and centrifuging the container toward the microstructured surface to form a sediment and a supernatant of the sample. Following centrifugation, the container can be inverted to decant at least a portion of the supernatant of the sample from the second portion, such that a concentrate (e.g., comprising the sediment) of the sample is retained in the microstructured surface. The concentrate can then be interrogated in the microstructured surface for the analyte of interest. In some embodiments, at least a portion of the second portion can be substantially transparent, such that the concentrate can be interrogated from the outside of the container, without requiring that the container be opened prior to interrogation.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for interrogating a sample for an analyte of interest, the method comprising: providing a container adapted to contain the sample, the container comprising a microstructured surface configured to provide capillary forces to retain a sample of interest; centrifuging the container toward the microstructured surface to form a sediment and a supernatant of the sample; inverting the container, after centrifuging the container, to decant at least a po…
