Polyanhydride‐Based Microparticles for Programmable Pulsatile Release of Diphtheria Toxoid (DT) for Single‐Injection Self‐Boosting Vaccines

open access: yesAdvanced Materials, EarlyView.
This study presents a polyanhydride‐based delivery platform for single‐injection, self‐boosting vaccines. The system enables programmable, pulsatile release of diphtheria toxoid with high antigen recovery and is guided by machine learning for tunability. In vivo results show immune responses comparable to multi‐dose regimens, highlighting its potential

Lack of telomerase reduces cancer incidence and increases lifespan of zebrafish tp53 M214K mutants

open access: yesScientific Reports
Telomerase activity is restricted in humans and telomere attrition occurs in several tissues accompanying natural aging. Critically short telomeres trigger DNA damage responses and activate p53 which leads to apoptosis or replicative senescence.

Controlling Lithium Surface Diffusivity via 2D PtTe2, PdTe2, and NiTe2 Coatings for Anode‐Free and Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Lithium plating mechanisms on 2D‐coated current collectors: PtTe2 coating enables rapid Li surface diffusivity, while PdTe2 and NiTe2 coatings shorten diffusion paths for Li adatoms. In addition, Li2Te, formed from PdTe2 and NiTe2 decomposition, reduces the critical nucleus size by lowering the interfacial energy between the electrolyte and deposited ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
