The custom laser scanning PA microscope was based on Olympus IX81 inverted microscope platform. Laser scanner was based on XY galvo mirrors (GVSM002, Throlabs Inc., Newton, NJ), pulsed lasers were coupled to the microscope via single mode optical fibers. The system was equipped with nanosecond lasers: 532 nm (LUCE 532, Bright Solutions, Italy), 671 nm (CrystaLaser, Reno NV) and 1064 nm (MOPA-M-10, MultiWave Photonics, Portugal) focused into the sample by a 10× objective (DPlan 10×, Olympus Inc). Acoustic waves were acquired by a non-focused 4.5 MHz transducer (model 6528101, 3.5 MHz, 4.5 mm in diameter; Imasonic Inc., Besançon, France) placed over the sample (transmission configuration). Signals from the transducer were amplified by a 20 dB amplifier (0.05–100 MHz bandwidth, AH-2010–100, Onda Corp.) and recorded by a PC equipped with a high-speed digitizer (PCI-5124, 12-bit card, 128 MB of memory, National Instruments, Austin, TX). System synchronization and laser triggering were performed by a digital waveform generator (DG4062, Rigol, Beijun, China). Laser beam spot size was estimated to be ~ 0.9 μm (FWHM) and laser step scan was 1 μm. For each sample point maximal amplitude of the acoustic wave was recorded. Optical microscopy images were collected by DP72 camera (Olympux Inc) using a custom ring illuminator mounted on the transducer, Figure 1B.

In vivo Photoacoustic Imaging of TCD Beads

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

PA imaging was taken to observe red TCD beads in vivo using a custom laser scanning PA microscope based on an Olympux IX81 inverted microscope platform. Galvo mirrors (6215H, Cambridge Technologies, Lexington, MA) were used to steer 532 nm and 820 nm laser beams (10 kHz pulse repetition rate) coupled to the microscope using single mode optical fibres. The focal area of the transducer (V316, 20 MHz, 12 m focal distance, Olympus-NDT Inc.) limited the imaging area to 150 μm. Cells were incubated in the chamber slides as mentioned above and the chamber walls were extended to accommodate the distance needed from the transducer to the area of interest. XYZ adjustment of the transducer position was obtained using a custom holder that positioned the transducer over the sample. Signals from transducer were amplified (5662B, Panametrics) and recorded by PC equipped with a high-speed digitizer (PCI-5124, 12-bit card, 128 MB of memory, National Instruments, Austin, TX). A digital waveform generator (DG4062, Rigol, Beijun, China) gave control over the mirrors and synchronization of the system. The signals generated from this scanning were then translated into an image using custom made software based on the LabView platform.

Skin Vibration Sensing Protocol

Two sensors of each of the three types were affixed to the skin and were placed 20 cm apart as shown in Supplementary Fig. 41. A 10 mm diameter VM (HUELE micro-motor) was attached to the skin using regular double-sided tape. It was placed between and equidistant from each of the two sensors. The VM was connected to a function generator (DG4062, RIGOL) set to 1000 Hz, 5 V_pp, 1.5 V DC offset, and ramp waveform. The output of the function generator was turned on and off to control motor-induced vibration. The vibration frequency of the VM was verified by applying lower frequencies (<10 Hz) that could be easily perceived and counted. TF analysis was performed in MATLAB using a window length of 50, 75% overlap, and Hamming window type for all the sensor types. The first supplemental experiment was performed by increasing the DC offset to 3 V (Supplementary Fig. 43a) and thereby increasing the vibration amplitude. The second supplemental experiment involved moving the VM closer to and on top of one of the DoS EP sensors (Supplementary Fig. 43b–e).

250 realizations of randomly chosen binary patterns or 32-order Hadamard matrix patterns are generated on a computer and used to drive the AWG (RIGOL DG4062, 60 MHz bandwidth, 2 channels). The output of AWG is divided into two paths, one is connected to the oscilloscope (R&S RTO2024, 2 GHz bandwidth) and another is connected to the RF driver of AOM1 (Gooch & Housego Fiber Q) to modulate the transmission of AOM1 and thus the temporal intensity of the 1542 nm signal.

The EL spectra were measured by applying a square-wave voltage of 400 Vpp (peak-to-peak voltage) at various frequencies produced using a function generator (DG4062, RIGOL) with a voltage amplifier (HA-405, PINTEK). The AC current was measured using a current meter (3706 A, Keithley), and the light emission was observed using a spectrometer (QEPro, Ocean Optics, Inc.) combined with a vertically aligned optical fibre equipped with a collimating lens. To measure the luminance, a spectroradiometer (PR-670, Photo Research Inc.) was used. The CIE coordinates were calculated from the measured EL spectra. Photographs were taken with a Canon EOS 70D using proper manual conditions to visualize the images regardless of their luminance.

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.
