Implementation Constraints

Use requires fabrication of DNA hydrogel materials and integration into a sensing device format. The abstract also places these systems in the context of flexible electronics, microfluidics, and wireless readout.; requires fabrication as a DNA-based material platform; device integration is discussed alongside flexible electronics, microfluidics, or wireless readout
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
