EcoFAB Device for Non-Invasive Root Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods face challenges in studying plant-microbe interactions, particularly in acidic and alkaline soils, due to the opacity of soil and irregular root growth patterns, which hinder high-resolution microscopy analysis of microbial-plant interactions around roots.
Innovation Solution
The development of EcoFAB devices with sterile plant growth chambers and mesh inserts allows for controlled spatial separation of plant roots from nutrients, enabling non-invasive in vivo imaging and manipulation of mycorrhizal interactions, facilitating the study of fungal contributions to nutrient accessibility and plant growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional microscopy methods are used to examine plant-microbe interactions, then high-resolution imaging can be achieved, but the opacity of soil and irregular root growth patterns make it difficult to examine the area around roots
Solution Approach 1:
The device segments the root growth environment by providing a defined growth chamber with a flat bottom surface, separating the root zone from the surrounding medium. This segmentation allows the root system to grow in a controlled, transparent environment that can be imaged without the opacity issues of natural soil
Solution Approach 2:
The patent introduces a transparent substrate or interface layer between the root system and the imaging system. This intermediary layer allows light to pass through while supporting root growth, enabling optical access to the root-microbe interaction zone without direct contact that would disrupt the natural interactions
2Productivity
If greenhouse pots, hydroponic pots, or agar seedling plates are used for plant growth, then plant cultivation is achieved, but dissection and mounting on slides is required for microscopy analysis which disrupts microbial species and root structures
Solution Approach 1:
The device merges the plant growth chamber with the microscopy observation chamber into a single integrated unit. The growth chamber bottom serves as the observation surface, combining cultivation and imaging functions that were previously separate, thereby eliminating the need for dissection and mounting operations
Solution Approach 2:
The flat bottom surface of the growth chamber serves multiple functions: it acts as both the growth substrate for roots and the imaging interface for microscopy. This multi-functional design allows the same structure to support both plant cultivation and high-resolution imaging without requiring separate preparation steps
3Reliability
If in vivo microscopy is performed without controlled environments, then time series microscopy without removal of microbial species or root structures is possible, but control over nutrient distribution and accessibility is lost
Solution Approach 1:
The device applies local quality control by creating distinct zones within the growth chamber - areas with different nutrient compositions, pH levels, or microbial inoculations can be established in specific locations. This allows localized manipulation of environmental conditions while maintaining overall system integrity for imaging
Solution Approach 2:
The system enables dynamic control of nutrient distribution through the ability to add, remove, or modify nutrient solutions in the growth chamber during the experiment. This dynamic capability allows researchers to change environmental conditions at different time points while continuously observing the effects on root-microbe interactions

AI summary
This disclosure provides systems, methods, and apparatus related to the determination of ecological processes. In one aspect, a device includes a base and a substrate in contact with a first side of the base. The base defines a stem port. The substrate and the first side of the base define a chamber. The chamber includes a root chamber and a first nutrient chamber. The root chamber and the first nutrient chamber are separated by a first mesh having openings of about 1 micron to 300 microns. The device is operable to house a plant, with roots of the plant being in the root chamber, and a stem of the plant passing through the stem port.
