Reactive ion etching of 4H-SiC using SF6/O2 for MEMS application [PDF]

open access: yes, 2013
Deep Reactive Ion Etching (DRIE) of 4H-SiC performed using SF6/O2 plasma. The etching rates investigated as a function of the ratio of the O2 flow rate to total gas flow rate under different etching conditions such as the effect of power density ...

Skin‐Interfaced Therapeutic Patches for Wound Fluid Management and Transdermal Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an integrated skin‐interfaced device combining microfluidics, hydrogel film technology, flexible electronics, and iontophoresis‐based transdermal delivery of PDRN to enhance wound healing. The device effectively manages wound fluid, maintains optimal moisture, and non‐invasively delivers therapeutic drugs.

Parylene etching techniques for microfluidics and bioMEMS [PDF]

open access: yes, 2005
Parylene C (poly(monochloro-p-xylylene)) is a member of a unique family of thermoplastic, crystalline polymers. Compared to other polymers, parylene films are exceptionally conformal and chemically inert owing to its vapor deposition polymerization (VDP)

Poking Pluripotency: Nanoinjection Into Human iPSCs

open access: yesAdvanced Materials, EarlyView.
Nanoinjection into hiPSCs: silicon nanotubes effectively transfect human induced pluripotent stem cells (hiPSCs) with mRNA, enabled by a delayed extracellular matrix application and enhanced surface functionalization. Nanoinjection is demonstrated with several reporter mRNA, including co‐transfection of mCherry and GFP.

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.
