Porous Coatings by Vapor Sublimation and Deposition for Molecular Channeling and Filtration in an Interstitial Fluid Microfiltration Device

Advanced Healthcare Materials, EarlyView.
A vapor‐based porous coating applied within nitinol tubes demonstrated complete suppression of cellular and tissue ingrowth, overcoming a major limitation of implantable interstitial fluid collection devices. Molecular channeling and diffusion are analyzed with probe molecules, showing reliable transport in vitro and in vivo. The coating also achieved >

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

Advanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

Advanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.
