Pr3+-doped YPO4 nanocrystal embedded into an optical fiber

Scientific Reports
Optical fiber with YPO4:Pr3+ nanocrystals (NCs) is presented for the first time using the glass powder—NCs doping method. The method’s advantage is separate preparation of NCs and glass to preserve luminescent and optical properties of NCs once they are ...

Biphasic Granular Bioinks for Biofabrication of High Cell Density Constructs for Dermal Regeneration

Advanced Healthcare Materials, EarlyView.
This study introduces a biphasic granular bioink (µInk) that enables 3D bioprinting of high cell density constructs for dermal regeneration. The bioink promotes cell proliferation, ECM deposition, and neovascularization, leading to tissue integration and reduced scar formation in vivo.

Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

Advanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted
