Consequently, it was chosen for cell viability studies. Prior to this, further particle size reduction and homogenization was carried out through a 40 min milling in a mixer mill MM400 (details can be found in the Supporting Information) and the optimized sample was labeled 10 mmol MM400. Fig. 7 shows the SEM images of as-prepared and agate mortar-milled 10 mmol sample for comparison. A large decrease in the powder particle size can be seen from the as-prepared sample (Fig. 7-a) to the mortar-milled ones (Fig. 7-b1-b2). In turn, a similar result is obtained for MM400-milled sample (Fig. 7-c1) and c2)), but with more homogeneous size distribution. It is worth noting that despite the slightly large size of the obtained powder particle (\u226410 \u03BCm), even after milling (Fig. 7-b3) and c3)), compared to the cells dimensions, many spherical-like structures of nanometer size (\u223C50 nm or less) are observed. These particles will interact directly with the cells and therefore their specific surface will be determinant for the viability studies.The work has been supported by the Ministerio de Ciencia e Innovaci\u00F3n (MCINN) through the projects PDC2022-133039-I00, PID2021-123112OB-C21-MICIIN, TED2021-129688B-C21, MAT2015-65445-C2-1-R, MAT2017-86450-C4-1-R, MAT2015-67557-C2-1-P, RTI2018-095856-B-C21, RTI2018-095303-A-C52, PID2020-114192RB-C41, PIE: 2021-60-E-030, PIE: 2010-6-OE-013, PID2021-122980OB-C51, FPI PRE2020-96246 grant (R.L-M.), and Comunidad de Madrid by NANOMAGCOST-CM, S2013/MIT-2850 NANOFRONTMAG, (MAD2D-CM)-UCM3, S2018/NMT-4321 NANOMAGCOST, 2018-T1/IND-1005 (A.E.) and S2022/BMD-7434 ASAP-CM.
