Impact of Sacrificial Layer Type on Thin-Film Metal Residual Stress

, 2009
In this paper we study the impact of two sacrificial layers on the final residual stress of thin gold films. In particular, we comapre a typical photoresist layer (Shipley SC1827) to single-crystalline silicon.

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Nanobody‐Conjugated Theranostic Prodrug Targeting αvβ3 Integrin Enables Precision Cancer Therapy With Real‐Time Imaging

Advanced Healthcare Materials, EarlyView.
The image shows a schematic form a nanobody‐conjugated theranostic prodrug (NBD) platform targeting tumor‐associated αvβ3 integrin. The NBD system integrates selective nanobody‐mediated tumor recognition, glutathione‐responsive disulfide cleavage for doxorubicin release, and aza‐BODIPY‐based near‐infrared fluorescence for real‐time imaging.

Soft Neural Interfaces for Circuit‐Level Analysis of Magnetogenetic Deep Brain Stimulation in Parkinson's Disease Models

Advanced Healthcare Materials, EarlyView.
ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.

GaAs high-contrast gratings with InGaP sacrificial layer for multi-wavelength VCSEL arrays

, 2016
We report on highly reflective suspended GaAs high-contrast gratings (HCGs) using an InGaP sacrificial layer. A high reflectivity approaching 100% was observed both in direct reflectivity measurement and by low threshold currents in fabricated multi ...
