UV-vis and Fluorescence Spectroscopy of Solutions

Check if the same lab product or an alternative is used in the 5 most similar protocols

UV-vis absorption spectra in solution (1 × 10^–5 mol L⁻¹) in a 1 cm quarts cuvette were collected on a Shimadzu UV-1750 spectrometer at resolution of 1.0 nm. Fluorescence spectra in solution were recorded on a Horiba Jobin Yvon spectrometer (Nanolog FL3-2iHR). The luminescence quantum yield in solution was measured using rhodamine 6G (under excitation of 488 nm, Φ_f = 0.88 in ethanol) as reference. The quantum yield Φ is calculated using the equation: Φ_u = [(A_sF_un²)/ (A_uF_sn₀²)]Φ_s, where A_s and A_u are the absorbance of the reference (or standard) and sample (or unknown) solutions at their respective excitation wavelengths, F_s and F_u are the corresponding integrated fluorescence intensity, and n and n₀ are the refractive indexes of the solvents of the sample and the reference, respectively^{39 (link)}.

Nuclear magnetic resonance (NMR) spectra were recorded on a Bruker Avance III 400 MHz NMR spectrometer (400 MHz for ¹H, referenced to TMS at δ =0.00 ppm and 100 MHz for ¹³C, referenced to CDCl₃ at 77.0 ppm). The hydrodynamic diameter and zeta potential of L1013 NPs were recorded on Micromeritics Nanoplus-3 (US). Transmission electron microscopy (TEM) images were obtained on a JEOL JEM-2100 electron microscope with an accelerating voltage of 200 KV. UV-vis-NIR spectra were measured on a Shimadzu UV-1750 spectrometer. Photoluminescence (PL) spectra were recorded on an Edinburgh instruments FLS980, using Xe lamp as the excitation source and a liquid nitrogen cooled InGaAs diode detector for signal detection. Fluorescence quantum yield was determined using IR26 in 1,2-dichloroethane (0.5%) as the standard. The absorbance of solutions was controlled below 0.1 to avoid internal filter effect.

UV-vis and UV-vis–NIR absorption spectra were respectively measured at room temperature on a Shimadzu UV-1750 spectrometer and a Shimadzu UV-3600 spectrophotometer with a resolution of 1.0 nm, using quartz cuvettes of 1.0-cm path length. The full absorbance spectrum of BisBDP2 NPs in PBS (300 to 1600 nm) was obtained by using quartz cuvettes of 0.5-cm path length. Fluorescence spectra of BDP1 were measured on a FLUOROMAX-4 spectrometer under an air atmosphere at room temperature; Fluorescent spectra of BDP2 and BisBDP1 were recorded using an Edinburgh FLSP920 fluorescence spectrophotometer equipped with a microsecond flash-lamp (UF900). NIR-II fluorescence spectra of BisBDP2 were recorded on a three-dimensional fluorescence spectrometer at room temperature.

For the determination of H₂O₂, enzyme activity, and phytohormones, nine apple seedlings were selected for each experimental replicate (n = 3) to provide an adequate amount of root and leaf tissue. The levels of hydrogen peroxide (H₂O₂, SO1300), and the activities of peroxidase (POD, KT5058), catalase (CAT, KT4957), abscisic acid (ABA, KT4924), and indoleacetic acid (IAA, NR, KT4992) were determined using commercial test kits purchased from Jiangsu Kete Biotechnology Co., Ltd. (Jiangsu, China). H₂O₂ was recorded on a UV-1750 spectrometer (Shimadzu, Japan). The enzyme activities were analyzed using an ELISA reader (Multiskan MS, Labsystems 325, Helsinki, Finland).

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.
