Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

open access: yesAdvanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Phase Distribution in Quasi‐2D Dion Jacobson Perovskite Dictates Ultrafast Energy Transfer and Directional Charge Transport

open access: yesAdvanced Materials Interfaces, EarlyView.
An efficient charge transfer and energy transfer at heterostructure interfaces is vital for optoelectronics. Quasi‐2D perovskites with varying layer thicknesses can create multiple interfaces, hindering charge transfer and energy transfer. Cesium Iodide (CsI) can help to redistribute these phases strategically, thereby enhancing energy transfer and ...

Ultrafast Dynamics of Complete Sb2S3 Solar Cells Unveiled via a Bifacial Architecture

open access: yesAdvanced Materials Interfaces, EarlyView.
Highly transparent, bifacial solar cells using a ZnO layer and indium tin oxide (ITO) are developed, enabling transient absorption spectroscopy (TAS) measurements. These bifacial cells show photovoltaic performance comparable to traditional cells. By integrating TAS and optical modeling, new insights into charge transfer mechanisms in Sb2S3‐based solar
