Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming arrays of membranes comprising amphipathic molecules are inefficient and lack a convenient and effective means to create stable, independent volumes of polar medium that can be used in high-throughput biological and pharmaceutical applications.
Innovation Solution
A method and apparatus involving a support with compartments and openings, where polar medium is introduced and constrained from neighboring compartments by an apolar medium, allowing formation of membranes at the interface through displacement of the apolar medium by polar medium, facilitating the creation of stable, independent volumes of polar medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used to form arrays of membranes, then the process is simple, but the efficiency and reliability are insufficient
Solution Approach 1:
The apparatus is divided into multiple compartments, each capable of holding separate volumes of polar medium. This segmentation allows parallel processing of multiple membrane formation reactions simultaneously, dramatically increasing productivity while maintaining a relatively simple overall device structure.
Solution Approach 2:
Volumes of polar medium are nested within compartments of the support structure, with apolar medium filling the spaces between them. This nested arrangement enables efficient use of space and facilitates the formation of membranes at the interfaces between polar and apolar phases without requiring complex positioning mechanisms.
2Reliability
If volumes of polar medium are allowed to contact each other, then the apparatus is simpler, but the stability and independence of individual reaction volumes is compromised
Solution Approach 1:
The support structure is segmented into multiple discrete compartments that physically separate volumes of polar medium. This segmentation ensures that each volume remains independent and stable, preventing cross-contamination while maintaining a straightforward compartment-based design.
Solution Approach 2:
An apolar medium acts as an intermediary substance filling the spaces between compartments and surrounding the polar medium volumes. This intermediary apolar phase creates a stable interface that maintains the independence of polar volumes while allowing the overall system to function cohesively.
3Productivity
If membranes are formed between droplets in a hydrophobic medium, then the method is straightforward, but the throughput and processing capability are limited
Solution Approach 1:
The apparatus employs a segmented array of compartments that can simultaneously hold and process multiple volumes of polar medium. This segmentation enables high-throughput processing by allowing parallel membrane formation in numerous compartments at once, while the standardized compartment design keeps manufacturing straightforward.
Solution Approach 2:
The support structure with its array of compartments serves multiple functions: it holds polar medium volumes, provides structural support, defines reaction chambers, and facilitates membrane formation at interfaces. This multi-functionality enables high-throughput processing without requiring separate specialized components for each function.

AI summary
An array of membranes comprising amphipathic molecules is formed using an apparatus comprising a support defining an array of compartments. Volumes comprising polar medium are provided within respective compartments and a layer comprising apolar medium is provided extending across the openings with the volumes. Polar medium is flowed across the support to displace apolar medium and form a layer in contact with the volumes, forming membranes comprising amphipathic molecules at the interfaces. In one construction of the apparatus, the support that comprises partitions which comprise inner portions and outer portions. The inner portions define inner recesses without gaps therebetween that are capable of constraining the volumes comprising polar medium contained in neighbouring inner recesses from contacting each other. The outer portions extend outwardly from the inner portions and have gaps allowing the flow of an apolar medium across the substrate.
