The study demonstrates the ability to precisely control the movement and behavior of these microstructures in a fluidic environment. The approach involves projecting specific light patterns that interact with the micro-objects, inducing directed motion. Key findings include the identification of optimal light pattern parameters, such as thickness and velocity, to achieve maximum manipulation efficiency. The research illustrates the potential for light-driven micro-manipulation in various applications, including microfluidics, particle sorting, and targeted delivery systems. Visual data, including SEM images and time-lapse microscopy sequences, are provided to showcase the microstructures and their controlled movements under different light pattern conditions. The document details experimental setups and results, highlighting the relationship between light pattern characteristics and the resulting motion of the helical structures. The velocity of the microstructures is analyzed in relation to variations in light pattern thickness, revealing a peak velocity at a specific thickness range. Furthermore, the document explores the phenomenon of electrotaxis, where the microstructures exhibit directed movement in response to applied electric fields, enhanced by the light-pattern induced properties. The effective escape and flip of the structures from confining circular light patterns are also documented, underscoring the dynamic control capabilities offered by this technique. The research contributes to the advancement of optical manipulation technologies for precise control of microscale objects with potential implications for advanced manufacturing and laboratory automation.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/controlled-manipulation-and-electrotaxis-of-microscale-helical-structures/181991/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/controlled-manipulation-and-electrotaxis-of-microscale-helical-structures/181991.png","ImageObject",300,407,{"name":42,"@type":43},"Seraphina","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-03","2026-09-02",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",10,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the main focus of the research presented in this document?","Question",{"text":63,"@type":64},"The main focus of the research is on the controlled manipulation and electrotaxis of microscale helical structures using light patterns generated by a spatial light modulator.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How is the movement of the micro-objects controlled?",{"text":68,"@type":64},"The movement of the micro-objects is controlled by projecting specific light patterns generated by a spatial light modulator, which interact with the microstructures to induce directed motion.",{"name":70,"@type":61,"acceptedAnswer":71},"What relationship is observed between light pattern thickness and maximum velocity for the helical structures?",{"text":72,"@type":64},"For the helical structures, the maximum velocity increases with light pattern thickness up to a certain point, after which it starts to decrease, indicating an optimal thickness for maximum velocity.
