To further make progresses in this sector, the development of point-of-care (POC) genetic testing technologies is crucial by offering the advantages to be fast, sensitive and specific, low cost, and, above all, able to be used onsite by nonspecialized people.

This study confirms that amide- and urea-functionalized NG undergo self-assembly to form supramolecular aggregates with a morphology that depends on the incorporated functional group.

These distinct morphologies suggest that amide groups drive NG stacking, whereas urea groups support NG vertically and horizontally, likely owing to differences in the strengths of single and bifurcated N<span></span>H/O hydrogen bonds. Moreover, the functional group incorporated into NG influences the gelation properties of the system.
