This study investigates nanoscale temperatures generated by photoexcited gold nanostars and their correlation with microscale thermal damage at the cellular level. Using X‐ray absorption spectroscopy and confocal microscopy in 3D cancer spheroids, it assesses localized heating effects and examines tumor cell structure and integrity, offering insights ...

A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...

Segmented PCL‐bisurea (BU) polymers and BU‐peptide conjugate additives assemble into fibrous superstructures at the nanoscale through a mix‐and‐matching strategy. Different bioactivities are incorporated through variation of peptide sequences. The resulting materials are screened for their effect on stem cell adhesion and pluripotency.

A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...
