Photopyroelectric tweezers for versatile manipulation.

ABSTRACT: Optical tweezers and related techniques offer extraordinary opportunities for research and applications in physical, biological, and medical fields. However, certain critical requirements, such as high-intensity laser beams, sophisticated electrode designs, additional electric sources, or low-conductive media, significantly impede their flexibility and adaptability, thus hindering their practical applications. Here, we report innovative photopyroelectric tweezers (PPT) that combine the advantages of light and electric field by utilizing a rationally designed photopyroelectric substrate with efficient and durable photo-induced surface charge-generation capability, enabling diverse manipulation in various working scenarios. These PPTs allow for remote and programmable manipulation of objects
