| Confocal fluorescence microscopy, rhodamine 6G-doped pSPA | A fluorescent signal extended continuously to the tip of the nanopipette, confirming that the pSPA had fully filled the lumen and formed a gel matrix free of voids |
| Capillary resistance | 150 mM KCl: (140.4 ± 4.3) × 10⁶ Ω, n = 6; 3 M pSPA gel: (34.4 ± 5.6) × 10⁶ Ω, n = 6; data are mean ± s.d.; solution-only resistance: n = 3 |
