Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring mechanical properties of cell nuclei are invasive, biased by isolation, and provide only average measurements of whole cells, failing to directly assess nuclear mechanics effectively.
Innovation Solution
A label-free cell analysis method using Brillouin light scattering techniques that simultaneously measures Brillouin metrics at multiple points within a sample, including the nucleus, allowing for non-invasive, submicron resolution classification of cells based on nuclear mechanical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If nuclear isolation is performed for mechanical measurement, then nuclear mechanical properties can be measured, but the measurement becomes invasive and biased
Solution Approach 1:
The patent uses Brillouin light scattering as an intermediary technique to measure nuclear mechanical properties through optical interaction rather than direct mechanical contact. The light beam acts as a mediator that probes the nucleus mechanically without physical isolation or contact, thereby eliminating the invasiveness and bias associated with traditional nuclear isolation methods while maintaining measurement precision
2Ease of manufacture
If average measurement of whole cell is used, then measurement process is simple, but nuclear mechanical properties cannot be directly assessed
Solution Approach 1:
The patent applies segmentation by spatially resolving the Brillouin scattering signal to distinguish different subcellular regions including the nucleus. Instead of measuring the whole cell as a single unit, the measurement is segmented to isolate nuclear mechanical properties from cytoplasmic contributions, enabling direct nuclear assessment while maintaining the non-invasive optical measurement approach
Solution Approach 2:
The patent implements local quality by focusing the measurement specifically on the nuclear region rather than the entire cell. The Brillouin scattering technique allows selective probing of local mechanical properties within the nucleus, providing site-specific mechanical information that distinguishes nuclear characteristics from the rest of the cell while keeping the measurement process relatively simple
3Measurement precision
If multiple points within nucleus are measured simultaneously, then measurement precision and detail are improved, but device complexity increases
Solution Approach 1:
The patent transitions from point-by-point sequential measurement to simultaneous multi-point measurement by introducing a spatial dimension to the Brillouin scattering detection. This dimensional approach allows multiple locations within the nucleus to be probed at once, improving measurement precision and detail while the optical nature of the technique keeps the added complexity manageable compared to mechanical probing systems
