Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

open access: yesAdvanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

Phase-shifted response of plasmonic nanostructures:Implications to luminescence upconversion [PDF]

open access: yes, 2017
We analyze the dynamics of a quantum dipole emitter (QDE) illuminated by a resonant electromagnetic field and placed close to a metal nanostructure, whose response to the incident field is phase shifted by 3π/2 (-π/2).

Photochemical upconversion present status and prospects for its application to solar energy conversion [PDF]

open access: yes, 2015
All photovoltaic solar cells transmit photons with energies below the absorption threshold bandgap of the absorber material, which are therefore usually lost for the purpose of solar energy conversion.
