Towards potential nanoparticle contrast agents: Synthesis of new functionalized PEG bisphosphonates

Beilstein Journal of Organic Chemistry, 2016
The use of nanotechnologies for biomedical applications took a real development during these last years. To allow an effective targeting for biomedical imaging applications, the adsorption of plasmatic proteins on the surface of nanoparticles must be ...

Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops

Advanced Functional Materials, EarlyView.
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

Biocompatible liquid-infused titanium minimizes oral biofilm adhesion in flow chamber and 3D implant-tissue-biofilm in vitro models

Bioactive Materials
Biomedical implants are susceptible to bacterial colonization, which can lead to challenging implant-associated infections. In particular, dental implant abutments – which are continuously exposed to bacteria within the oral cavity – stand to greatly ...

3D Hydrodynamic Flow Lithography

Advanced Functional Materials, EarlyView.
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

Histomorphometric analysis of bone deposition at Ti implant surface dip-coated with hydroxyapatite (In vivo study)

Journal of Baghdad College of Dentistry, 2014
Background: Synthetic hydroxyapatite,(Ca10(PO4)6(OH2) can directly bond to bones without infection and fibrous encapsulation, thus is regarded as bioactive and biocompatible.

Effect of a gold–palladium coating on the long-term adhesion of human osteoblasts on biocompatible metallic materials

Surface and Coatings Technology, 2006
Our ambition for several years is to study the in vitro interface between human bone cells and biomedical metals in order to improve dental and orthopaedic implant's surface. The long-term adhesion of human osteoblasts cultured on pure titanium, titanium alloy and stainless steel substrates presenting 4 different surface morphologies and 2 different ...

Sulfation‐Tunable Peptide‐Glycosaminoglycan Hydrogels for Hematopoietic Stem and Progenitor Cell Expansion

Advanced Functional Materials, EarlyView.
Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.

Wearable Kirigami‐Apertured Capacitive Sensors for Continuous Cardiac Volumetric Monitoring

Advanced Functional Materials, EarlyView.
A wearable kirigami‐apertured carbon nanotube‐paper composite (K‐CPC) capacitive sensor enables cardiac volumetric monitoring. The kirigami process creates a central aperture with cantilevered fibers that confine the electric field, enhancing both sensitivity and lateral resolution.
