“…Post-synthesis modification is an effective means to prepare MOFs with ECL properties. The mechanism is mainly to attach luminophores to the surface of MOFs by ligand reaction, electrostatic force adsorption, or amide bonding, so that the MOFs materials, originally without ECL properties, become nanocomposites with ECL properties [79,80].…”

“…Then, a power amplifier (75A250A, Amplifier Research Inc., USA) was used to amplify these signals to 80 Vp-p, which excited the motor driving the IVUS catheter. For ultrasound transmission, the electrical signals (1 cycle sinusoidal pulse at 41.5 MHz with a pulse repetition frequency of 2500 Hz) were transmitted from the Verasonics Vantage 64LE high-frequency ultrasound system (Verasonics Inc., USA) to the single-element transducer when a synchronized trigger was obtained from the function generator [34]. Then, the same ultrasound system recorded the digitized ultrasound signals, eventually stored in a computer.…”

“…The basic performance characterization of a motor, such as vibration, maximum speed, optimal working distance, rotary uniformity, positioning accuracy, and SNR competition, must be tested first before the imaging evaluation. Our proposed helical ultrasonic motor design was partially shown in a conference proceeding [34]; however, the system performance was not previously described and the conducted in vitro experiments were primitive.

Existing three-dimensional (3D) intravascular ultrasound (IVUS) systems that combine two electromagnetic (EM) motors to drive catheters are bulky and require considerable efforts to eliminate EM interference (EMI). Herein, we propose a new scanning method to realize 3D IVUS imaging using a helical ultrasonic motor to overcome the aforementioned issues. The ultrasonic motor with compact dimensions (7-mm outer diameter and 30-mm longitudinal length), lightweight (20.5 g), and free of EMI exhibits great application potential in mobile imaging devices. In particular, it can simultaneously perform rotary and linear motions, facilitating precise 3D scanning of an imaging catheter. Experimental results show that the signal-to-noise ratio (SNR) of raw images obtained using the ultrasonic motor is 5.3 dB better than that of an EM motor. Moreover, the proposed imaging device exhibits the maximum rotary speed of 12.3 revolutions per second and the positioning accuracy of 2.6 µm at a driving voltage of 240 Vp-p. 3D wire phantom imaging and 3D tube phantom imaging are performed to evaluate the performance of the imaging device. Finally, the in vitro imaging of a porcine coronary artery demonstrates that the layered architecture of the vessel can be precisely identified while significantly increasing the SNR of the raw images.

Advancements in robotic surgery help to improve the endoluminal diagnosis and treatment with minimally invasive or non-invasive intervention in a precise and safe manner. Miniaturized probe-based sensors can be used to obtain information about endoluminal anatomy, and they can be integrated with medical robots to augment the convenience of robotic operations. The tremendous benefit of having this physiological information during the intervention has led to the development of a variety of in vivo sensing technologies over the past decades. In this paper, we review the probe-based sensing techniques for the in vivo physical and biochemical sensing in China in recent years, especially on in vivo force sensing, temperature sensing, optical coherence tomography/photoacoustic/ultrasound imaging, chemical sensing, and biomarker sensing.
