“…In fact, during the years, different fields of technological and biological applications have found in the optical tweezers, a revolutionary method for safe and no contact manipulation of particles, cells, and DNA. [ 22 ] More in details, optoelectronic photovoltaic tweezers (PVT), based on the use of ferroelectric crystals (i.e., lithium niobate [LN]), have recently proposed advantages over the conventional optoelectronic technique, ability to keep their manipulation properties on and active, even after the illumination period. The PVT could be used for the manipulation of electrically charged as well as neutral particles, biological materials, and samples more in general for biotechnological applications.…”

Liquids are the primary environments in which chemical, physical, and biological processes occur. Considering a liquid bridge as liquid unit volume (LUV) element, it is highly desirable to develop reliable tools for handling such volumes. Herein, a sort of intelligent microfluidic platform based on the pyroelectric‐electrohydrodynamics (EHD) is shown for manipulating liquid bridges and thus performing multiple functions in a flexible and simple way. Several basic operations with liquid bridges using an EHD‐pin matrix based on the pyroelectric effect engineered in ferroelectric crystals are demonstrated. By activating pyro‐EHD effect in predetermined positions (pins of the array), the locomotion and handling of single or multiple LUVs simultaneously are controlled. In particular, multiple operations such as lift, displacement, mixing, stretching, and carrying vector for microparticles, are shown. These tweezers based on a pyro‐EHD matrix can open the route for a multipurpose platform driven by physical intelligence and can be used for driving locomotion and operate manifolds functionalities in many areas of science and technology at microscale as well as nanoscale with advantages to be activated by the sole thermal stimulus, controlled remotely, and in noncontact mode.

Bài báo trình bày kết khảo sát số quang lực tác động lên hạt nano trong chùm tia laser có cấu trúc Gauss vòng. Chùm tia có phân bố cường độ theo hàm Gauss vòng tạo ra từ các hệ quang phi tuyến được mô tả gần đúng bằng biểu thức toán học. Trên cơ sở đó, chúng tôi tính quang lực tác động lên các vi hạt có kích thước nano với chiết suất lớn hơn và nhỏ hơn chiết suất môi trường. Phân bố quang lực trong không gian chùm tia đã được khảo sát số, phân tích và bình luận nhằm mục đích nghiên cứu động học của các vi hạt trong kìm quang học.
