As a wirelessly powered implantable LED device, NFC (near-field communication) LED chips (Kyoritsu Electronics Industry, Osaka, Japan; model: KP- NFLEG (λ = 530 nm), size: 7.0 × 11.0 × 0.8 mm, weight: ~ 20 mg) were encapsulated with a UV-curable resin based on urethane polymer (STAR Lab Cosmetics, Osaka, Japan).
A handmade antenna board was used for the wireless power supply. An electromagnetic induction system was used for the power supply system with a resonance frequency of 13.56 MHz and the transmission power was 3 W. The antenna board can provide power supply with a transmission distance ranging from 0 to 105 mm from the upper side of the antenna board. The size of the antenna board was 310 mm (w) × 230 mm (d) × 105 mm (h), which was sufficient for covering the size of a mouse cage.
The central wavelength of light emitted from the LED device was confirmed using a photonic multichannel spectral analyzer system (PMA-11, Hamamatsu Photonics K.K., Hamamatsu, Japan). The light intensity of each LED device was measured using a power meter with a photo-diode sensor (PD300-UV, Ophir, Saitama, Japan) and LED devices with a power of 50–60 µW were selected and used for the mPDT experiment. Devices in which wires had been mechanically broken were used as non-emitting devices for controls.

A polarizing optical microscope (Nikon, Eclipse LV-100 POL) was used to observe the optical texture of the samples. The reflectance and transmittance spectra were acquired with a spectrometer (PMA-11, Hamamatsu) coupled to the microscope by a bundled fiber with diameter of 1 mm and an objective lens with 10× magnification. The measurement spot was approximately 100 µm in diameter, which is larger than the patterning pitch (2.6 × 2.6 μm²).

For the experiments in Figs. 2 and 3, the left-handed ChLC material was prepared by mixing a LC mixture (Merck, MLC-2140) with a left-handed chiral dopant (HCCH, S-5011) at a weight ratio of 98.8:1.2. For the waveguide experiment (Fig. 5), the two materials were mixed at a slightly different weight ratio of 97.7:1.3. In all experiments, the ChLCs were injected into the patterned cells in the isotropic phase (100 °C) and cooled to room temperature at a rate of 0.3 °C/min. The reflection spectrum was measured using a home-built microscope setup equipped with a ×4 objective and an optical fiber with 1 mm diameter coupled to a spectrometer (Hamamatsu, PMA-12). The transmission spectrum was measured on a polarizing optical microscope (Nikon, LV-100-POL) equipped with a ×10 objective and a 1 mm-thick optical fiber coupled to a spectrometer (Hamamatsu, PMA-11).

To evaluate the adsorption ability of cyt.c on the ITO electrode surface, the PBS solution in the SOWG cell was continuously exchanged by using a pipette (PIETMAN, M&S Instruments Inc., Japan) by hand. This process is described as washing process in this manuscript. In this process, 0.8 mL of PBS solution in the cell attaching to the ITO electrode surface was extracted, and the same amount of the fresh PBS solution was supplied to the cell by using a micropipette so as to never expose the electrode surface to the air, and repeated 100 times or more in one experiment.

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.
