Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

open access: yesAdvanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

open access: yesAdvanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Lung fibrosis and exposure to wood dusts: Two cases report and review of the literature [PDF]

open access: yes, 2015
Introduction: Increasing evidence suggests that idiopathic pulmonary fibrosis (IPF) occurs more often in subjects previously exposed to wood dusts than in non-exposed subjects.
