Actuation of Cell Layers in Three Dimensions

Advanced Materials, Volume 38, Issue 34, 17 June 2026.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the

Flexible 3D Multi‐Material Printing beyond Layer‐by‐Layer Constraints via Sequential Multi‐Printer Fabrication

Advanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
We developed a flexible multi‐material printing strategy that employs sequential printing with different printers. This combined use of printers expands the accessible material scope. Moreover, incorporating Xolography as a sequential step enables support‐free, contactless printing, thereby enhancing structural design flexibility beyond conventional ...

Optical Pulling Force on Gold Mie Particles via Germanium and Aluminum‐Based Structures

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates a novel approach to generate optical pulling force on gold Mie objects of two different shapes and studies the effects for different object sizes, incident angles, and the aluminum tetrahedra separation. Using rectangular germanium blocks combined with aluminum tetrahedra, optical pulling force (OPF) is achieved over a broad ...

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes

Advanced Science, Volume 13, Issue 32, 9 June 2026.
We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...
