| 1 | Enhanced Light-Harvesting Efficiency and Adaptation: A Review on Visible-Light-Driven Micro/Nanomotors显示文摘As visible light accounts for a larger proportion of solar energy and is harmless to living organisms,it has the potential to be the energy source of micro/nanomotors,which transform visible-light energy into mechanical motion,for different applications,especially in environmental remediation.However,how to precisely control the motion of visible-light-driven micro/nanomotors(VLD-MNMs)and efficiently utilize the weak visible-light photon energy to acquire rapid motion are significant challenges.This review summarizes the most critical aspects,involving photoactive materials,propulsion mechanisms,control methods,and applications of VLD-MNMs,and discusses strategies to systematically enhance the energyharvesting efficiency and adaptation.At first,the photoactive materials have been divided into inorganic and organic photoactive materials and comprehensively discussed.Then,different propulsion mechanisms of the current VLD-MNMs are presented to explain the improvement in the actuation force,speed,and environmental adaptability.In addition,considering the characteristics of easy control of VLD-MNMs,we summarized the direction,speed,and cluster control methods of VLD-MNMs for different application requirements.Subsequently,the potential applications of VLD-MNMs,e.g.,in environmental remediation,micropumps,cargo delivery,and sensing in microscale,are presented.Finally,discussions and suggestions for future directions to enhance the energy-harvesting efficiency and adaptation of VLD-MNMs are provided. | Dekai Zhou Rencheng Zhuang Xiaocong Chang Longqiu Li | 2020 | Research2020，，1： | 3 |

| 3 | Magnetic Nanomotor-Based Maneuverable SERS Probe显示文摘Surface-enhanced Raman spectroscopy(SERS)is a powerful sensing technique capable of capturing ultrasensitive fingerprint signal of analytes with extremely low concentration.However,conventional SERS probes are passive nanoparticles which are usually massively applied for biochemical sensing,lacking controllability and adaptability for precise and targeted sensing at a small scale.Herein,we report a“rod-like”magnetic nanomotor-based SERS probe(MNM-SP)that integrates a mobile and controllable platform of micro-/nanomotors with a SERS sensing technique.The“rod-like”structure is prepared by coating a thin layer of silica onto the self-assembled magnetic nanoparticles.Afterwards,SERS hotspots of silver nanoparticles(AgNPs)are decorated as detecting nanoprobes.The MNM-SPs can be navigated on-demand to avoid obstacles and target sensing sites by the guidance of an external gradient magnetic field.Through applying a rotating magnetic field,the MNM-SPs can actively rotate to efficiently stir and mix surrounding fluid and thus contact with analytes quickly for SERS sensing.Innovatively,we demonstrate the self-cleaning capability of the MNM-SPs which can be used to overcome the contamination problem of traditional single-use SERS probes.Furthermore,the MNM-SPs could precisely approach the targeted single cell and then enter into the cell by endocytosis.It is worth mentioning that by the effective mixing of intracellular biocomponents,much more informative Raman signals with improved signal-to-noise ratio can be captured after active rotation.Therefore,the demonstrated magnetically activated MNM-SPs that are endowed with SERS sensing capability pave way to the future development of smart sensing probes with maneuverability for biochemical analysis at the micro-/nanoscale. | Yong Wang Yuhuan Liu Yang Li Dandan Xu Xi Pan Yuduo Chen Dekai Zhou Bo Wang Huanhuan Feng Xing Ma | 2020 | Research2020，，1： | 1 |
| 4 | 3D printing of high-precision and ferromagnetic functional devices显示文摘The development of projection-based stereolithography additive manufacturing techniques and magnetic photosensitive resins has provided a powerful approach to fabricate miniaturized magnetic functional devices with complex three-dimensional spatial structures.However,the present magnetic photosensitive resins face great challenges in the trade-off between high ferromagnetism and excellent printing quality.To address these challenges,we develop a novel NdFeB-Fe_(3)O_(4) magnetic photosensitive resin comprising 20 wt.%solid loading of magnetic particles,which can be used to fabricate high-precision and ferromagnetic functional devices via micro-continuous liquid interface production process.This resin combining ferromagnetic NdFeB microparticles and strongly absorbing Fe_(3)O_(4) nanoparticles is able to provide ferromagnetic capabilities and excellent printing quality simultaneously compared to both existing soft and hard magnetic photosensitive resins.The established penetration depth model reveals the effect of particle size,solid loading,and absorbance on the curing characteristics of magnetic photosensitive resin.A high-precision forming and ferromagnetic capability of the NdFeB-Fe_(3)O_(4) magnetic photosensitive resin are comprehensively demonstrated.It is found that the photosensitive resin(NdFeB:Fe_(3)O_(4)=1:1)can print samples with sub-40μm fine features,reduced by 87%compared to existing hard magnetic photosensitive resin,and exhibits significantly enhanced coercivity and remanence in comparison with existing soft magnetic photosensitive resins,showing by an increase of 24 times and 6 times,respectively.The reported NdFeB-Fe_(3)O_(4) magnetic photosensitive resin is anticipated to provide a new functional material for the design and manufacture of next-generation micro-robotics,electromagnetic sensor,and magneto-thermal devices. | Zhiyuan Huang Guangbin Shao Dekai Zhou Xinghong Deng Jing Qiao Longqiu Li | 2023 | International Journal of Extreme Manufacturing2023，5，3： | 0 |
| 5 | A Bioinspired Soft Robot Combining the Growth Adaptability of Vine Plants with a Coordinated Control System显示文摘Tip-extending soft robots,taking flexible film or rubber as body material and fluid pressure as input power,exhibit excellent advantages in constrained and cluttered environments for detection and manipulation.However,existing soft continuum robots are of great challenges in achieving multiple,mutually independent,and on-demand active steering over a long distance without precise steering control.In this paper,we introduce a vine-like soft robot made up of a pressurized thin-walled vessel integrated with the high controllability of a control system with multiple degrees of freedom in three dimensions.Moreover,steering and kinematic models to relate the steering angle and robot length to the location of the robot tip are provided,and a dynamic finite element model for analyzing the motion of the spatial consecutive steering is established.We demonstrate the abilities of disinfection of the robot moving in a long and tortuous pipeline and detection in a multi-obstacle constrained environment.It is established that the robot exhibits great advantages in active consecutive steering over a long distance,high controllability in completing more complex path planning,and significant ability of carrying operational tools for ventilation pipeline disinfection and multi-obstacle detection.The bionic soft robot shows great promise for use in environment sensing,target detecting,and equipment servicing. | Pengchun Li Yongchang Zhang Guangyu Zhang Dekai Zhou Longqiu Li | 2022 | Research2022，，1： | 0 |
| 6 | Potential application of functional micro-nano structures in petroleum显示文摘This paper takes micro-nano motors and metamaterials as examples to introduce the basic concept and development of functional micro nano structures, and analyzes the application potential of the micro-nano structure design and manufacturing technology in the petroleum industry. The functional micro-nano structure is the structure and device with special functions prepared to achieve a specific goal. New functional micro-nano structures are classified into mobile type(e.g. micro-nano motors) and fixed type(e.g. metamaterials), and 3 D printing technology is a developed method of manufacturing. Combining the demand for exploration and development in oil and gas fields and the research status of intelligent micro-nano structures, we believe that there are 3 potential application directions:(1) The intelligent micro-nano structures represented by metamaterials and smart coatings can be applied to the oil recovery engineering technology and equipment to improve the stability and reliability of petroleum equipment.(2) The smart micro-nano robots represented by micro-motors and smart microspheres can be applied to the development of new materials for enhanced oil recovery, effectively improving the development efficiency of heavy oil, shale oil and other resources.(3) The intelligent structure manufacturing technology represented by 3 D printing technology can be applied to the field of microfluidics in reservoir fluids to guide the selection of mine flooding agents and improve the efficiency of mining. | LIU He JIN Xu ZHOU Dekai YANG Qinghai LI Longqiu | 2018 | Petroleum Exploration and Development2018，45，4： | 0 |
