Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

open access: yesAdvanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Therapeutic Reprogramming of Glioblastoma Phenotypic States Using Multifunctional Heparin Nanoparticles

open access: yesAdvanced Science, EarlyView.
This study presents heparin‐derived nanoparticles (HP‐NPs) as a novel precision medicine platform that combines therapeutic and delivery functions. HP‐NPs target drug‐resistant glioblastoma stem cells, reprogramming them into a drug‐sensitive phenotype and significantly reducing tumor progression.

Non‐Destructively Quantifying the Whole‐Course Growth and Drug‐Response of PDOs by an Automatic Microfluidic System Utilizing Chemiluminescence Detection

open access: yesAdvanced Science, EarlyView.
The detection of secreted biomarkers enables molecular variations monitoring of organoid status. In this study, the non‐destructive quantification for the whole‐course growth and drug‐response of PDOs is first realized using a multifunctional microfluidic chip‐based system(ASMO) that integrates culturing, drug incubation, and biomarker detection ...

Coexistence of left ventricular noncompaction and double-orifice mitral valve in a patient with congestive heart failure

open access: yesThe Turkish Journal of Pediatrics, 2012
Left ventricular noncompaction (LVNC) is a rare cardiomyopathy. It usually presents with ventricular dysfunction, thromboembolic events and arrhythmias. An asymptomatic clinical course is also possible.

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

open access: yesAdvanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Ultra‐Sensitive and Linear Flexible Pressure Sensors with Tri‐Scale Graded Microstructures for Advanced Health Monitoring and Robotic Perception

open access: yesAdvanced Science, EarlyView.
A flexible piezoresistive sensor with a 3D tri‐scale graded microstructure is proposed, overcoming the trade‐off between sensitivity and linearity. The device achieves ultra‐high sensitivity (138.6 kPa−1), a broad linear range (400 kPa, R2 = 0.99), and exceptional stability (24 000 repeated loading cycles), enabling precise detection of physiological ...
