Tg 209 f3 tarsus instrument

Thermogravimetric analysis was performed using a TG 209 F3 Tarsus instrument (NETZSCH, Selb, Germany). The open corundum crucible was used for measurements. The analyzed samples were heated at 5 °C/min from 25 to 900 °C under a nitrogen atmosphere (flow rate, 30 mL/min).

The PXRD patterns of the Cu-BTCs were recorded using a Rigaku MiniFlex diffractometer (Rigaku Corp., Neu-Isenburg, Germany). FTIR spectra were measured on a Nicolet iS10 FTIR spectrometer with KBr pellets (Thermo Fisher Scientific, Waltham, MA, USA). TGA was performed using a TG 209 F3 Tarsus^® instrument (NETZSCH, Burlington, MA, USA). The surface morphology and elemental composition of Cu-BTC were characterized using SEM-EDS (FE-SEM, JEOL JSM-5800F, Peabody, MA, USA). N₂ adsorption isotherms were obtained by using a BELSORP-mini II instrument (BEL Japan, Inc., Tokyo, Japan). High-purity (99.999%) gases were used throughout the adsorption experiments. All samples were activated by rinsing them thoroughly, followed by drying under vacuum for 24 h prior to the gas sorption measurements.

PXRD patterns of Cu-MOF, PS, and PS@Cu-MOF were recorded using a Rigaku MiniFlex diffractometer (Rigaku Corp, Neu-Isenburg, Germany). The FT-IR spectrum was measured on a Bio-Rad FTS 135 spectrometer (Hercules, CA, USA). DSC runs were carried out using a DSC 214 Polyma (NETZSCH, Burlington, MA, USA). TGA was performed using a TG 209 F3 Tarsus^® instrument (NETZSCH, Burlington, MA, USA). The surface morphology and elemental composition of PS and the PS@Cu-MOF scaffolds were characterized using SEM-EDS (FE-SEM, JEOL JSM-5800F, Peabody, MA, USA). The mechanical properties of PS and PS@Cu-MOF were evaluated using a TA rheometer (Discovery HR 10, New Castle, DE, USA). The degradation of PS@Cu-MOF was carried out by ICP-MS (Agilent Marker 7700, RF Generator Power 1550 W, Tokyo, Japan). The colorimetric absorbance was determined using a microplate reader (Synergy H1, BioTek, Winooski, VT, USA), and the live/dead double-stained cells were imaged by fluorescence microscopy (IX83, Olympus, Center Valley, PA, USA).
