Raman spectroscopy analysis was conducted using multiple instruments and excitation wavelengths due to the inherent low scattering properties of the samples. FT-Raman spectra were recorded using an Equinox 55 Bruker FT-IR spectrometer (Karlsruhe, Germany) with an integrated FRA-106S Raman module. A nitrogen-cooled Ge detector and a 1064 nm line excitation from an Nd: YAG laser was employed. A Renishaw InVia Reflex confocal Raman microscope, using a 632.8 nm He-Ne excitation and 100× objective (NA 0.9) provided the best output in terms of signal-to-background ratio. For measurement optimization, sampling droplets of colloidal nanoparticle suspension were drop-coated on a SpectRim TM hydrophobic microscopy plate. An excitation line from a Cobalt diode pumped solid state laser at 532 nm, an He-Ne laser operating at 632.8 nm, and a laser diode at 785 nm were employed for excitation. Parameter optimization was controlled from the Wire 3.4 software of the instruments. The spectral resolution was 0.5 cm−1 for visible line excitation and 1 cm−1 for NIR.

Example 13

Samples of CSM and cis-2-decenoic acid were weighed before and after lyophilization to determine the amount of KBr to add to each sample. KBr was added at 10 times the sample mass and mixed using a mortar and pestle. The resulting powder was formed into a pellet using a Carver 4350 Manual Pellet Press (Carver Inc., Wabash, Ind., USA). Pressure was applied at 10 Tons for 10 min. IR spectra were obtained using a Bruker Equinox 55 FT-IR spectrometer at room temperature in the range of 3500 cm−1 to 400 cm−1 at a resolution of 1 cm−1. The final spectra represent the mean of 128 scans. Each sample was measured in triplicate.

Transmission electron microscopy (TEM) samples were prepared by pipetting a 10 μL drop of as-synthesized NPs at a concentration of 0.125 mg/mL onto a copper TEM grid with lacey carbon film. TEM was conducted on a FEI T12 microscope operated at 120 kV, equipped with a Gatan CCD image system with digital micrograph software program. Powder X-ray diffraction (PXRD) patterns were collected on as-synthesized Fe3O4 NPs deposited on a glass substrate using a Bruker D8 Advance using Cu Kα radiation (λ= 1.5418 Å), with the background from the glass substrate subtracted. Transmission Fourier transform infrared (FTIR) spectroscopy measurements were recorded on a Bruker Equinox 55 FT-IR spectrometer in the range of 4000 cm−1 to 400 cm−1 at 2 cm−1 resolution on NPs in a potassium bromide (KBr) pellet, at a sample mass loading of 0.33 wt.%. Thermogravimetric analysis (TGA) was carried out using a TA Instruments Q500 thermal analysis system under a N2 atmosphere and at a constant heating rate of 10 °C/min from 100 °C to 600 °C. All samples were first heated to 100 °C and held at that temperature for 3 min to remove adsorbed water. Dynamic light scattering (DLS) and zeta-potential (ζ-potential) measurements was carried out using a Malvern Zetasizer Nano and three independent measurements were made for each sample.

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.
