Chemical Validation of Plant VOCs
A study validating invisible plant signals through chemical reactions.
Chemical Validation
Making an invisible signal observable
To validate plant communication, this experiment based on chemical exposure methods, converts invisible BVOCs into visible and comparable visual signals, forming the primary sensing layer of a multi-scale olfactory system.
It explores whether invisible biological emissions can be translated into a visible material response before being captured through electronic sensors and computational models. Its purpose is to examine the detectability and behaviour of plant-emitted volatile signals and to establish an initial basis for evaluating the feasibility of BVOC-based sensing.
Principle
The colourimetric indicator undergoes a state change under the influence of BVOCs, varying with time and environmental conditions.

Materials List
Setup
Petri dish
Filter paper
Aluminium zip bag
Reagents
Sodium bisulfite
(NaHSO₃)Basic fuchsin reagent
pH strips
Procedure
1. Prepare indicator paper
2. Apply reagent to substrate
3. Seal in controlled chamber
4. Wait fixed time interval
5. Record color state
Record
This experiment have constructed a culture dish status matrix that includes four control groups.
The experiment records the state of each group at each stage, for example:
Time (no change / partial / full shift),
Response (fast / moderate / slow),
Stability (persistent / reversible / fading),
Tag (stable / shifted / saturated).
Outcome
Schiff's reagent exhibits a colour reaction with certain aldehydes, typically manifesting as a shift from pale to magenta. Injured plants often release increased quantities of early defence-associated volatiles such as (GLVs), which may contain aldehyde components. Consequently, there exists an opportunity for more pronounced colour differences to develop within enclosed spaces.
This experiment focuses primarily on concept validation, response speed, intensity, and spatial patterns, thereby laying the groundwork for prototyping and machine learning.
Development
Invisible chemistry to ecological sensing
This research ultimately evolved into Olfaction — an ecological sensing system that captures volatile organic compounds (VOCs) and translates them into actionable intelligence for environmental monitoring and early intervention.
