Microneedles Mediated Delivery of Nanodiamonds for Quantum Sensing of Free Radicals in Skin Tissue

Advanced Materials Technologies, EarlyView.
Fluorescent nanodiamonds are nanoscale sensors capable of monitoring cellular stress responses. However, to function effectively, they must be delivered into cells or tissues. Here, we demonstrate their application in the skin by developing a dissolvable microneedle platform that dissolves after skin insertion, enabling the delivery of nanodiamonds ...

Patterned Screen‐Printing Process for Substrate‐Free and Scalable Hyaluronic Acid Microneedle Arrays

Advanced Materials Technologies, EarlyView.
A substrate‐free microneedle array comprising a hybrid hyaluronic acid ink was fabricated via a scalable screen‐printing process for flexible transdermal drug delivery. Defect‐free mold filling was achieved using a vacuum‐assisted jig and a delayed drying system, and the use of this versatile platform for multi‐drug patterning and ex vivo skin ...

Mitigating Cancer Therapy–Related Cognitive Impairment by Targeted Activation of Undruggable Phosphatase

Advanced Science, EarlyView.
An RVG‑engineered exosomal saRNA delivery system (RVG‑EVs‑saPtpro) effectively targets and activates hippocampal PTPRO, functioning as a “molecular brake” to alleviate cancer therapy‑related cognitive impairment (CTRCI) by enhancing neuronal survival, neurogenesis, and synaptic plasticity.

Oral Motion‐Powered Smart Dental Implant Abutment for In Situ Antibacterial and Cell Adhesion Through Piezoelectric Effect

Advanced Science, EarlyView.
We proposed a method based on the piezoelectric effect and fabricated an implant abutment on the basis of piezoelectric ceramic. Under physiological occlusal pressure, the oral motion‐powered smart dental implant abutments interacted with water and oxygen, promoting the formation of reactive oxygen species and achieving a synergistic and highly ...
