UV−visible spectra were collected using a BioTek spectrophotometer (Synergy H1, USA). Images of the nanomaterials were taken using a transmission electron microscope (FEI Titan, 80–300 LB, Hillsboro, OR, USA). An Agilent Cary 630 FTIR spectrometer (Santa Clara, CA, USA) was used for Fourier Transform Infrared (FTIR) measurements. Raman spectra were obtained using Raman spectroscopy (NRS-7100, JASCO Corporation, Tokyo, Japan).

Electronic absorption and CD spectra were
measured with a spectrophotometer (UV-2450, Shimadzu) and a spectropolarimeter
(J-820, JASCO), respectively. Fluorescence emission spectra were measured
with a fluorescence measurement system (C9920-03G, Hamamatsu Photonics),
and apparent fluorescence quantum yields of B850 BChl a were estimated from the emission between 820 and 950 nm using software
installed in this system. High-performance liquid chromatography (HPLC)
was performed with a pump (LC-20AT, Shimadzu) and a detector (SPD-M20A
or SPD-20A, Shimadzu). Resonance Raman spectra were recorded on a
Raman microscope (NRS-7100, JASCO).

Transmission electron microscope (TEM) images of the fabricated membranes were observed using a JEM-2100F electron microscope (JEOL Ltd., Tokyo, Japan). Field Emission Scanning Electron Microscope (FE-SEM) images were observed using JSF-7500F electron microscope (JEOL Ltd.). Atomic force microscopy (AFM) images were observed using a SPA-400 (Hitachi High-Tech Science, Tokyo, Japan). The AFM observation was performed with an OMCL-AC160TS-C3 cantilever (OLYMPUS, Tokyo, Japan) in dynamic force mode. The crystal structures of the fabricated membranes were measured by powder X-ray diffraction (XRD) (Ultima IV Protectus, Rigaku Corp., Tokyo, Japan) using monochromatized Cu Kα radiation (at 40 kV and 40 mA). The ζ-potential of the sample surfaces was measured using an electrokinetic analyzer (SurPASS™ 3; Anton Paar, Graz, Austria) in 1 mmol/L of KCl aqueous solution. The surface chemical state of the membrane was analyzed using XPS (JPS-9200, JEOL Ltd.). Raman spectroscopy was recorded using a 532 nm laser (NRS-7100, JASCO, Tokyo, Japan). The samples for Raman spectroscopy were prepared by dropping each colloidal solution on a glass plate and drying.

The degradation stability was evaluated in Exf. BP NSs and BP-PEG@Au-GSH-DOX samples which contained the same BP NSs (20 ppm) in deionized water. The observations and analysis were conducted at three environmental conditions [I. inert conditions in an Ar glove box (23 ± 2 °C, 5 ± 2% RH), II. cooling temperature conditions (4 ± 2 °C, 60 ± 5% RH), and III. ambient atmospheric conditions (23 ± 2 °C, 71 ± 3% RH)] for a period of four weeks. The morphological and chemical properties of the samples were observed at predetermined time intervals using a scanning transmission electron microscope (STEM, JEM2100F, JEOL) at 200 kV, Raman scattering (JASCO, NRS-7100), and X-ray photoelectron spectroscopy (XPS, Shimadzu AXIS ULTRA DLD).

The crystalline properties of the synthesized nanocomposites were studied using an X-ray diffractometer (SmartLab, Rigaku) under Cu Kα radiation. The morphology of the synthesized nanocomposite was investigated using field emission scanning electron microscopy (FESEM: Thermo Fisher Scientific, Apero2) and transmission electron microscopy (TEM, JEOL JEM-2100). The surface elemental composition and oxidation states were analyzed using X-ray photoelectron spectroscopy (XPS; PHI5000 VersaProbe II ULVAC-PHI, Japan) at the Synchrotron Light Research Institute (SLRI) in Thailand. Raman spectra were recorded using a microscopy Raman spectrometer (NRS-7100, JASCO). The current–voltage (I–V) characteristics of the fabricated photovoltaic devices were studied using a Class A solar simulator workstation (SL-50A-WS, SCIENCE TECH) at AM1.5 (sunlight of 100 mW/cm2). For electrochemical impedance spectroscopy (EIS) measurements, the electrolyte solution consisted of 0.05 M I2 and 0.5 M LiI in acetonitrile. Nyquist plots were recorded over a frequency range of 0.1 Hz–100 kHz and measured at 250 mV to negate the limited regime of mass transport.
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.
