Table 2. Effect of crosslinking on the size of Ncs. All samples are prepared according to the general procedure using 5 wt% of EC in AcOEt (see also Table S1, Section S5 of the SI). A high-power ultrasound probe is used as the homogenizer.

Entry	Cargo	Crosslinker	Avg. dimensionsa
1	Vanillin	—	190 ± 45 nm
2	Vanillin	BTCA	270 ± 96 nm
3	Vanillin	TMPG	167 ± 35 nm
4	Vanillin	TMPG-BTCA	217 ± 60 nm
5	—	TMPG-BTCA	96 ± 40 nm
6	Vanillin	TMPG-TREN	170 ± 40 nm
7	—	TMPG-BTCA + borax	117 ± 40 nm

^aAverage dimensions of capsules are measured from SEM images (SI, Section 7.2) over a sample of 100 objects. Values are reported as mean ± standard deviation.
