Controlled Clustering of Superparamagnetic Nanoparticles using Block Copolymers : Design of New Contrast Agents for Magnetic Resonance Imaging

, 2005
When polyelectrolyte-neutral block copolymers are mixed in aqueous solutions with oppositely charged species, stable complexes are found to form spontaneously. The mechanism is based on electrostatics, and on the compensation between the opposite charges.

Copolymers of Poly(Butylene Trans‐1,4‐Cyclohexanedicarboxylate)/Pripol as New Biomaterial Platform for Small Diameter Vascular Graft

Advanced Healthcare Materials, EarlyView.
Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Piezoelectric Surface Charge and Dynamic Stimulation Synergize to Promote Cardiac Myoblast Alignment and Maturation

Advanced Healthcare Materials, EarlyView.
Surface polarization of PVDF films combined with mechanical stimulation generates piezoelectric electrical cues that modulate cardiomyoblast behaviour. Non‐poled and poled PVDF substrates provide distinct electroactive microenvironments influencing cell adhesion, proliferation, and differentiation.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...
