🔮 Why this matters:
Reconfigurable soft microfluidics point toward adaptive chemical matter, embodied computation, and future closed-loop chemical learning systems. #physicalintelligence #softmatter #adaptivematerials

🧱 Key message:
We add a new computational dimension - hardware-level programmability - to chemical computing.
Function is reassigned by physical reconfiguration, not molecular redesign.

🧠 These patterns become computation:
The material system itself acts as a physical reservoir, enabling analogue & reservoir computing.
Nonlinear functions are recovered with a simple linear readout: The complexity lives in the material. #reservoircomputing

🌊 Then things get fun:
With a pH oscillator, reconfigurable geometry gives rise to standing chemical waves. Emergent spatiotemporal patterns from the interplay of reaction dynamics × flow × structure. #complexity #oscillator #noneqsys

🧬 We show this first with switchable DNA logic:
AND ↔ OR gates realized using the same DNA network — logic reassigned purely by reconfiguring microfluidic flow paths. #DNAnanoscience

🔁 This enables something powerful:
The same molecular system can perform different computations simply by changing physical structure.
No new DNA strands. No new chemistry. Just new geometry. #chemicalcomputation #systemschemistry

💡 The core idea:
Instead of encoding computation only in chemistry, we make the reaction vessel itself programmable.
Soft hydrogel structures can be written & erased in situ, reshaping flow, mixing, and reaction environments on demand. #3Dprinting #microfluidics
