Dynamic light scattering (DLS) and zeta potential (ζ-potential) measurements were carried out on Malvern Zetasizer Nano (Malvern Instrument Ltd., Worcestershire, UK). For DLS studies, Fe3O4@CaCO3 was diluted in deionized water to a concentration of 100 μg/mL. Transmission electron microscopy (TEM) images were obtained on a JEM-1400 (Jeol, Tokyo, Japan). Images were captured using a side-mounted Veleta digital camera (EM SIS, Muenster, Germany). UV-vis spectra were recorded on a UV-2100 spectrophotometer (Shimadzu, Kyoto, Japan) and microplate reader Clariostar (BMG, Ortenberg, Germany). FTIR spectra were measured on a 640-IR FT-IR spectrometer (Varian, MA, USA) from 4000 to 400 cm−1 at room temperature accompanied with a KBr pellet.

FTIR spectra were obtained with a Varian 640-IR FTIR® spectrometer (Varian Inc., Palo Alto, CA, USA), equipped with a universal ATR sampling accessory. A small quantity of the individual compounds (PSO, 5-MOP, and HP-β-CD) or PSO-HP-β-CD and 5-MOP-HP-β-CD inclusion complex (1:1) and physical mixtures were placed on the diamond ATR crystal. Analysis was performed over a wavelength ranging from 4000 to 400 cm−1 with a resolution of 4 cm−1.

Melting points (uncorrected) were determined on a Stuart™ SMP40 automatic melting point apparatus. 1H and 13C NMR spectra were recorded on a Bruker Fourier 300 spectrometer (300 MHz), using DMSO-d6 as a solvent and TMS as an internal reference. IR spectra were recorded on a Varian 640-IR FT-IR spectrometer using KBr mode. Microwave-assisted reactions were performed in closed vessel focused single mode using a CEM Discover SP microwave synthesizer (CEM, USA). The reaction temperatures were measured by an equipped IR sensor.

Nanoparticle size, charge and polydispersity were determined by dynamic light scattering (DLS) using a Malvern Nano Zetasizer ZS Series. Fourier transform infrared spectroscopy (FTIR) spectra were recorded in the range of 400-4000 cm -1 at a resolution of 4 cm -1 on a Varian 640-IR FTIR spectrometer. UV-Visible spectra were recorded using a Perkin Elmer Lambda 35 in the range 400-600 nm at 0.1 nm increments. Stress testing AuNP stability in high ionic solutions (1 M NaCl) was conducted by UV/Vis measurement of the characteristic plasmon peak over 24 h. Serum stably was established using DLS following a 24 h incubation medium containing 10% or 40% foetal calf serum.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
