Classification: CPC G  C | IPC C  G

Claim 12:
13. A system comprising:
a microfluidic device configured to perform an assay on a sample of tumor cells, wherein the microfluidic device comprises:
a surface comprising randomly affixed tumor cells comprising one or more unknown subtypes of the tumor cells,
a channel configured to deliver the sample to the surface and flow a plurality of aptamers over the tumor cells to allow the aptamers to interact and bind to the tumor cells, wherein the plurality of aptamers comprises a plurality of aptamer families, and each aptamer family of the plurality of aptamer families is determined by a prediction model to bind to at least one possible subtype of the tumor cells, and
a detector configured to obtain data points that make up a data signal associated with a measure of binding affinity of each of the plurality of aptamer families to the tumor cells;

one or more data processors; and
a non-transitory computer readable storage medium containing instructions that, when executed on the one or more data processors, cause the one or more data processors to perform actions including:
obtaining the data signal from the microfluidic device;
analyzing the measure of the binding affinity of each aptamer family to the tumor cells, wherein the analyzing comprises classifying the binding affinity of each aptamer family to the tumor cells; and
determining one or more aptamer families that characterize the one or more unknown subtypes of the tumor cells based on the classifying.
