Isolation Defines Identity: Functional Consequences of Extracellular Vesicle Purification Strategies
Advanced Healthcare Materials, EarlyView.Four extracellular vesicle purification strategies are compared using ovarian‐cancer ascites and ES‐2 cell supernatants. A novel workflow links purification to function by combining particle‐normalized proteomics with matched cell‐free and cell‐based assays.

From RNA to DNA: How Cargo Identity Reprograms Lipid Nanoparticle Architecture and Function
Advanced Healthcare Materials, EarlyView.The evolution of lipid nanoparticles (LNPs) spans from RNA‐LNPs, used in mRNA vaccines, to DNA‐LNPs, ideal for gene therapies. Emerging bionano architectures, decorated with DNA and plasma proteins, pave the way for advanced DNA‐based therapies that are more stable, targeted, and customizable.

Do Ceramic Femoral Heads Reduce Taper Fretting Corrosion in Hip Arthroplasty? A Retrieval Study
Clinical Orthopaedics and Related Research, 2013 BackgroundPrevious studies regarding modular head-neck taper corrosion were largely based on cobalt chrome (CoCr) alloy femoral heads. Less is known about head-neck taper corrosion with ceramic femoral heads.Questions/purposesWe asked (1) whether ceramic

Analytic solution for the limiting shape of profiles due to fretting wear
Scientific Reports, 2014 We consider fretting wear due to tangential oscillations of two contacting bodies. For small oscillation amplitudes, the wear occurs only in a circular slip zone at the border of the contact area.
