FT-IR spectra of the polysaccharide TMP-B were measured by grinding a mixture of polysaccharide with dry KBr, then pressing into pellets. Fourier transform infrared spectra of the TMP-B was collected using a Thermo Nicolet 6700 spectrometer (Thermo Scientific, New York, USA) operating in the range of 400 - 4000 cm-1 at a resolution of 2 cm-1.

The morphology of the TNB was observed with field-emission scanning electron microscope (SEM, JSM-7600 F, JEOL Ltd., Japan). The crystal structure of samples was identified by PANalytical X-ray diffractometer (XRD, PANanalytical, Westborough, MA). The chemical structure of surface-modified TiO2 was analyzed by X-ray photoelectron spectra (XPS)(PHI 5000 Versa Probe system Physical Electronics, Chanhassen, MN); and the deconvolution of XPS peak was carried out using the PHI Multipak™ software with the Gauss-Lorentz line and Shirley background subtraction (Physical Electronics, Chanhassen, MN). The monolayer on the TNP was further characterized by Fourier transform infrared spectra (FTIR), and measured under the transmission mode with a Thermo Nicolet 6700 spectrometer (ThermoFisher, Houston, TX). The zeta potential and aggregate size of the ENM was measured using electrophoretic light scattering with a Malvern Zetasizer Nano-ZS instrument (Malvern Instruments Ltd., Worcestershire, UK). The Malvern software established a number of pseudo-replicate runs (usually 10 to 20) to establish one value and these were repeated 3 times for an average value. The standard deviations of these data were always less than 10% of the means, and most were less than 5% indicating very little variance in the replications.

All the nanostructures’ characterization was performed with the synthesis product in powder form. In order to study the morphology and elemental composition of the nanostructures, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) inside an AURIGA CrossBeam workstation were performed (Zeiss, Oberkochen, Germany). The structural characterization was carried out by X-Ray diffraction (XRD) using X’Pert PRO MRD diffractometer (PANalytical, Royston, UK) with Cu Kα radiation and the data acquisition range was 10–90° (2θ) with a step size of 0.033°. Fourier-transform infrared (FTIR) spectra were acquired in the range of 4000–525 cm−1 with 4 cm−1 resolution and 45° incident angle. The data was recorded using a Smart iTR attenuated total reflectance (ATR) sampling accessory (Thermo Scientific, Waltham, MA, USA) equipped with a single bounce diamond crystal on a Thermo Nicolet 6700 Spectrometer (Thermo Scientific, Waltham, MA, USA). Raman spectra were acquired using an inVia Reflex micro-Raman spectrometer (Renishaw, Wotton-under-Edge, UK) equipped with an air-cooled CCD detector and a HeNe laser using a 532 nm laser excitation with a power of 50 mW, with 0.3 cm−1 resolution. All measurements were obtained with an intensity of 50 µW at room temperature in a range of 100–1600 nm, using an integration time of 2 scans (10 s each).

The identification of CG-CuNPs was investigated by Fourier-transform infrared spectroscopy (FTIR) using a Thermo Nicolet 6700 spectrometer (Thermo Scientific Inc., MA) with the attenuated total reflection (ATR) technique in the spectral range from 4000 to 400 cm À1 . The powdered sample was placed onto the ATR crystal and the sample spectrum was collected. The spectrum from CG-CuNPs was compared to that of purified CG.
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.
