Oscillating microbubble array–based metamaterials (OMAMs) for rapid isolation of high-purity exosomes

Xinjia Li, Zhiting Deng, Wenjun Zhang, Wei Zhou et autres

Exosomes secreted by cells hold substantial potential for disease diagnosis and treatment. However, the rapid isolation of high-purity exosomes and their subpopulations from biofluids (e.g., undiluted whole blood) remains challenging. This study presents oscillating microbubble array-based metamaterials (OMAMs) for enabling the rapid …

Holographic surface-acoustic-wave tweezers for functional manipulation of solid or liquid objects

Peng-Qi Li, Wei Zhou, Benxian Peng, Chunqiu Zhang et autres

Noninvasive surface-acoustic-wave (SAW) tweezers provide a powerful tool for on-chip object manipulation. However, the piezoelectric materials for generating SAWs are anisotropic with misaligned directions of wave momenta and energy flow, making the conventional interdigital transducer (IDT) inappropriate for perfect SAW control. Here …

Diffusive skin effect and topological heat funneling

Pei‐Chao Cao, Ying Li, Yu‐Gui Peng, Minghong Qi et autres

Abstract Non-Hermitian wave system has attracted intense attentions in the past decade since it reveals interesting physics and generates various counterintuitive effects. However, in the diffusive system that is inherently non-Hermitian with natural dissipation, the robust control of heat flow is hitherto …
