The prepared NPs were analysed in terms of their morphological, chemical and topographical properties. The morphological observations of the prepared nanopowders were made by FE-SEM (Hitachi S-4700, Japan) and TEM (JEOL JEM JSM 2010, Japan). Apart from these characterizations, AFM was also utilized to check the surface topographical behaviour (horizontal, vertical and lateral size of grown NPs). For AFM (Veeco, USA) observations, the sample was prepared on the silicon substrate by dropping an liquid dispersion of NPs and dried at room temperature for about 30 min. The crystallinity, phases and size of the prepared powder was characterized by XRD with CuKα radiation (λ = 1.54178 Å, Rigaku, Japan) in the range of 20–80° with a 6° min−1 scanning speed with 40 kV and 30 mA current. Fourier transform infrared spectroscopy (FTIR, PerkinElmer GX spectrophoto meter) measurements were analysed in the range 4000–400 cm−1.

The morphology and size of the Fe 3 O 4 -PEG-CD56/ Avastin@Ce6 nanoprobes were examined by Transmission electron microscopy (TEM, JEM-2100 electron microscope, JEOL, Japan). One hundred NPs were randomly selected and analyzed by ImageJ software. TGA of the Fe 3 O 4 -PEG-CD56/Avastin@Ce6 NPs were acquired by a Thermo gravimetric analyzer (Pyris 1 TGA, Perkin Elmer, America) under a N 2 atmosphere at a heating rate of 20 °C/min. The UV-visible absorption spectrum was acquired with a Varian Cary 50 spectrophotometer. FTIR spectroscopy was performed with a PerkinElmer GX spectrophotometer. The T2 relaxation times of increasing concentrations of the nanoprobe were measured with a 3.0 T MRI system.

Electronic spectra of suspension were recorded on Varian UV−visible spectrophotometer (Carry 100 Bio). FT-IR spectra (4000–400 cm−1) were collected on a Perkin-Elmer GX spectrophotometer (U.S.A) using KBr disks. The zeta potentials were recorded using a Malvern instrument (Zetasizer, Nano series, Nano-ZS90). Scanning electron microscope (SEM) (Leo series 1430 VP) equipped with INCA was used to determine the morphologies of samples. Transmission electron microscopy (TEM) was performed using a JEOL JEM 2100 microscope. Thermogravimetric analysis (TGA) was done using Mettler Toledo TGA/DSC 1 analyzer. Powder X-ray diffraction (XRD) measurements were conducted on Rigaku smart lab automated multipurpose X-ray diffractometer system with CuKα1 radiation (λ = 1.540593 Å) in the 2θ range of 20–70° at scanning speed of 3° per minute with 0.01° scan step size. The Brunauer− Emmett−Teller (BET) surface area analysis was conducted on an Autosorb iQ, version 1.11 (Quantachrome Instruments).
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.
