Interaction of cultured human endothelial cells with polymeric surfaces of different wettabilities [PDF]

open access: yes, 1985
The in vitro interaction of human endothelial cells (HEC) and polymers with different wettabilities in culture medium containing serum was investigated. Optimal adhesion of HEC generally occurred onto moderately wettable polymers.

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Copolymers of N-(4-bromophenyl)-2-methacrylamide with 2-hydroxyethyl methacrylate

open access: yeseXPRESS Polymer Letters, 2007
The radical-initiated copolymerization of N-(4-bromophenyl)-2-methacrylamide (BrPMAAm) with 2-hydroxyethylmethacrylate (HEMA) was carried out in 1,4-dioxane solution at 70°C using 2,2’-azobisisobutyronitrile (AIBN) as an initiator with different monomer ...

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Development and AFM study of porous scaffolds for wound healing applications [PDF]

open access: yes, 2004
An engineering approach to the development of biomaterials for promotion of wound healing emphasises the importance of a well-controlled architecture and concentrates on optimisation of morphology and surface chemistry to stimulate guidance of the ...

Timing Mechanotransduction: Mechanically Dynamic Biomaterials Reveal the Temporal Hierarchy of YAP/TAZ Control Nodes

open access: yesAdvanced Science, EarlyView.
This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...

Poly(2-hydroxyethyl methacrylate): A new star polymer [PDF]

open access: yes, 2015
Multiarm star polymers are attractive materials due to their unusual bulk and solution properties. They are considered analogues of dendrimers with a wide range of applications, such as drug delivery, membranes, coatings and lithography.1 The advent of ...

Fracture Resistance of Compromised Endodontically Treated Teeth Restored with Bonded Post and Cores: An in Vitro Study [PDF]

open access: yes, 2015
Statement of problem: It is unclear which post and core system performs best when bonded to severely compromised endodontically treated teeth. Purpose: The purpose of this study was to investigate the fracture resistance and mode of failure of severely ...

Thermally Degradable Biocompatible Hydrogel as Transient Encapsulation Coating for Implantable Sensors

open access: yesAdvanced Science, EarlyView.
A biocompatible hydrogel coating with tissue‐like mechanics and reversible dissolution triggered by a mild, physiologically compatible temperature drop (≈37°C → ≈25°C) was developed for the transient encapsulation of implantable devices. The physically crosslinked methylcellulose, polyethylene glycol and polyacrilic acid (MC/PEG/PAA) hydrogel ...
