Nanovial Reaction Chambers for Linked Single-Cell Assays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current assay formats lose cell-specific information during processing due to cell pooling, necessitating a platform that retains and links functional single-cell data with genomic, transcriptomic, and proteomic information.
Innovation Solution
Nanoscale reaction chambers (nanovials) conduct assays while maintaining cell-specific information, enabling correlation of assay outcomes with genomic, transcriptomic, and proteomic analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cell pooling is used in standard assay formats, then data gathering efficiency is improved, but cell-specific information is lost
Solution Approach 1:
The invention segments the assay system into separate functional modules: (1) nanoscale reaction chambers that maintain physical separation of individual cells throughout the assay, (2) barcode labeling systems that assign unique identifiers to each nanochamber, and (3) integrated analysis systems that link functional assay data with genomic/transcriptomic data through the barcode. This segmentation prevents information loss while maintaining assay efficiency.
Solution Approach 2:
The invention introduces barcodes as intermediary elements that bridge different types of data. Each nanochamber receives a unique barcode that serves as a persistent identifier, allowing functional assay results to be linked with genomic and transcriptomic information without requiring physical manipulation or pooling of cells, thus preventing information loss.
2Loss of information
If single-cell assays are performed, then cell-specific information is retained, but assay complexity and processing difficulty increase
Solution Approach 1:
The invention merges multiple assay types (functional assays, genomic analysis, and transcriptomic analysis) into a single integrated platform. By performing all assays on the same physically separated single cells within nanoscale reaction chambers and using common barcode identification, the system reduces overall complexity compared to performing separate assays on pooled cells or requiring multiple separate processing steps.
Solution Approach 2:
The nanoscale reaction chamber serves multiple functions simultaneously: it maintains physical separation of cells, provides a containment environment for functional assays, serves as a platform for barcode attachment, and enables integration with genomic and transcriptomic analysis. This multi-functionality reduces the need for separate specialized components.
3Adaptability or versatility
If multiple assays are performed on single cells, then multi-dimensional analysis is achieved, but processing time and resource requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-labeling nanochambers with barcodes before cells are introduced, and by preparing all necessary reagents and containment structures in advance. This allows multiple assays to be performed in parallel on different nanochambers simultaneously, reducing total processing time while maintaining the ability to perform genomic, transcriptomic, and functional analyses on the same cells.
Solution Approach 2:
The invention enables continuous processing by maintaining cells in their nanoscale reaction chambers throughout all assay steps, eliminating the need to disrupt or re-suspend cells between assays. The barcode system allows seamless transition between functional assays, genomic analysis, and transcriptomic analysis without interrupting the continuous monitoring and processing of individual cells.
