Functionalized nanowires for miRNA-mediated therapeutic programming of naïve T cells
Ex vivo engineering of T cells for adoptive T-cell therapy without pre-activation is challenging and hinders therapeutic efficacy. Here, using nanowires, the delivery of microRNAs to primary naïve mouse and human CD8+ T cells without pre-activation for immune protection against pathogens is demonstrated.

Complex free-space magnetic field textures induced by three-dimensional magnetic nanostructures
In magnetic double nanohelices, the balance of geometrical effects and dipolar interaction results in strongly coupled three-dimensional spin states. This leads to topological features in the stray field, offering a new route to pattern the magnetic induction.

Ultrafast hole spin qubit with gate-tunable spin–orbit switch functionality
Quantum computing requires fast and selective control of a large number of individual qubits while maintaining coherence, which is hard to achieve concomitantly. All-electrical operation of a hole spin qubit in a Ge/Si nanowire demonstrates the principle of switching from a mode of selective and fast control to idling with increased coherence.
