The morphology of the received V₂O₅ NWs was studied through SEM SU82400 from Hitachi. The nanostructure crystallinity was studied using XRD with Cu Kα₁ radiation on the Bruker D8 Venture kappa geometry diffractometer equipped with a Photon‐II CPAD detector. The scans were performed in the 2θ range from 10° to 50° at a scanning rate of 0.02° s⁻¹. Room‐temperature Raman spectra of as‐received V₂O₅ NWs were obtained using a LabRAM HR system (Horiba Jobin Yvon). An excitation wavelength of 532 nm and a power <1 mW was used. A lens of 100× magnification was used to focus the laser beam and to collect the scattered light dispersed by a holographic grating with 2400 lines/mm.

A Raman experiment was performed using a Horiba LabRAM HR system under ambient conditions using a laser with a wavelength of 514 nm. We used a low incident laser power less than 0.5 mW with a spot size of ~1 μm and a short irradiation time of 10 sec to prevent any additional degradation of the graphene by the laser irradiation during the Raman measurement.

Samples pretreatment and SCRS acquisition were performed as we previously described with slight modification (Teng et al., 2016 (link); Tao et al., 2017 (link)). In brief, SCRS were obtained using a Clinical Antimicrobial Susceptibility Test Ramanometry instrument (CAST-R; Qingdao Single-Cell Biotech Inc, China) or a modified confocal Raman-fluorescent microscope based on LabRam HR system (Horiba Ltd., U.K.). The acquisition time for each cell was 1 s.
Pre-processing of raw SCRS data was performed using R (version 3.5.1), including background subtraction and area normalization. Spectra were cropped to a spectral region of interest ranging from 600 cm⁻¹ to 1800 cm⁻¹ for chemometrics analysis.

All the single-cell Raman spectra were acquired on a RACS-Seq system (Qingdao Single-cell Biotech, China) or a LabRam HR system (Horiba, France). The spectra were analyzed with LabSpec 6 software and customized scripts. The Raman bands in SCRS from carotenoid-containing cells were determined and further analyzed to establish a relationship between the significant Raman shifts and ¹³C absorption. The Raman bands in SCRS of carotenoid-containing cells from a ¹²C-labeled sample were used as controls. Cells with a ¹³C shift in SCRS were isolated using the RAGE chip as described above. After that, the tube which contained the target cells in a one-cell-one-tube manner was then moved into a laminar hood, and lysis buffer (Qiagen, USA) was added for the following cell lysis.

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.
