Abstract Manipulation of single cells or particles is crucial in the biomedical field. However, precisely and rapidly manipulating without damaging them a significant challenge. In this study, novel strategy for indirect manipulation microparticles that can satisfy these requirements via combination particle‐induced dielectrophoretic forces (PiDEP) optoelectronic tweezers (OET) developed. This based primarily on principle experiencing same tend to repel each other, whereas those different are attracted other. During manipulation, Ag‐SiO 2 controlled by OET act as intermediaries other through forces. Thus, range be expanded two three times its original size, speed significantly increased while maintaining precision. Furthermore, results indicate proposed method effectively reduce cell damage one‐third caused traditional OET. study demonstrates potential particle‐assisted single‐cell offers an effective microparticles.

The tumor microenvironment functions as a dynamic and intricate ecosystem, comprising diverse array of cellular non-cellular components that precisely orchestrate pivotal behaviors, including invasion, metastasis, drug resistance. While unraveling the interplay between behaviors represents tremendous challenge, recent research illuminates crucial biological phenomenon known mechanotransduction. Within microenvironment, mechanical cues like tensile stress, shear stiffness play role by activating mechanosensitive effectors such PIEZO proteins, integrins, Yes-associated protein. This activation initiates cascades intrinsic signaling pathways, effectively linking physical properties tissues to their physiological pathophysiological processes morphogenesis, regeneration, immunity. mechanistic insight offers novel perspective on how within impact behaviors. intricacies are yet be fully elucidated, it exhibits distinct attributes from non-malignant tissues, elevated solid stresses, interstitial hypertension, augmented matrix stiffness, enhanced viscoelasticity. These traits exert notable influences progression treatment responses, enriching our comprehension multifaceted nature microenvironment. Through this innovative review, we aim provide new lens decipher contexts, broadening knowledge these factors promote or inhibit thus offering valuable insights identify potential targets for anti-tumor strategies.
