Vhx 700f digital microscope

The surface morphology and shape of CL‐NS‐loaded DMN arrays were examined by using a Keyence VHX‐700F Digital Microscope (Keyence, Osaka, Japan) and a TM3030 benchtop scanning electron microscope (SEM) (Hitachi, Krefeld, Germany). The latter was used in low vacuum mode at a voltage of 15 kV. In the case of NS particles, visualization inside the DMN arrays was achieved by SEM with a Quanta FEG 250 (FEI, Hillsboro, OR, USA) at an acceleration voltage of 10–20 kV under high chamber pressure (8 × 10⁻⁵ mbar) with standard SEM carbon tape as background.

The surface morphology and shape of DFS-NS-DMNs were examined using a Keyence VHX-700F Digital Microscope (Keyence, Osaka, Japan) and a TM3030 benchtop scanning electron microscope (SEM) (Hitachi, Krefeld, Germany). The latter was used in low vacuum mode at a voltage of 15 kV.

The surface morphology and shape of AmB-NE-DMN were examined by using optical and scanning electron microscopy. A Keyence VHX-700F Digital Microscope (Keyence, Osaka, Japan) and TM3030 benchtop scanning electron microscope (SEM) (Hitachi, Krefeld, Germany) were used for evaluation. The SEM was used in low vacuum mode at a voltage of 15 kV [38 (link)].

Microscopy images were obtained using a Leica EZ4 D digital microscope (Leica, Wetzlar, Germany) and a Keyence VHX-700F Digital Microscope equipped with a VH-Z20R lens (Keyence, Osaka, Japan). OCT images were recorder using an EX1301 OCT Microscope (Michelson Diagnostics Ltd., Kent, UK) and analysed using the imaging software ImageJ^® (National Institutes of Health, Bethesda, USA).

Methylene blue (MB, 2% w/w) and fluorescein sodium (Flu—Na, 20% w/w), as a water-soluble blue (absorption wavelength of 664 nm) and red dye (absorption wavelength of 450 nm) respectively, were mixed into the PL (20% w/w) solutions and used as a model low molecular weight drugs. BSA-FITC (20% w/w), as a high molecular weight model protein with an excitation/emission wavelength of 480/520 nm, was dissolved in the PL solutions as well. Another model biomolecule, insulin (20% w/w), was dissolved in a 0.1 M HCl solution and then added to the PL solutions. These model drugs loaded PL DMN were prepared as per the described process in Section 2.4 and Fig. 1. The morphology of drug-loaded DMN patches was investigated using a Keyence VHX700F Digital Microscope (Keyence, Osaka, Japan). In addition, scanning electron microscopy (TM3030 benchtop SEM, Hitachi, Krefeld, Germany) was used for high-resolution imaging. The instrument was operated at 15 kV and images were captured at magnifications between 40 and 250×.

Vouchers of Marsdeniayarlungzangboensis were collected from Motuo County, Xizang of China. The photographs and phenology data were obtained during the field expeditions.
Morphological observations and measurements of the new species were carried out based on living plants and dry specimens. The morphology of opened corolla, opened calyx, gynostegium and staminal corona, pistil, pollinarium were observed by using a Keyence VHX-700F Digital Microscope (Keyence, Osaka, Japan) and based on dry specimens. All morphological characters are described according to the terminology presented by Li et al. (1995) .
