Biomimetic Surfaces (biomimetic + surface)
Selected AbstractsBiomimetic Surfaces for High-Performance OpticsADVANCED MATERIALS, Issue 46 2009Yunfeng Li High-performance antireflective and antifogging surfaces are fabricated on planar silica substrates and planconvex lenses. Such surfaces dramatically suppress reflection over a large range of wavelengths and a large field of view. Additionally, the ARS surfaces exhibit high-quality superhydrophilic properties. For antireflective and antifogging applications, the ARS surfaces exhibit more high-quality mechanical stability and better durability than multilayered films.

A versatile microfluidic strategy to rapidly and selectively immobilize gradients of virtually any desired protein on soft poly(ethylene glycol) (PEG) hydrogel surfaces is developed by S. Cosson et al. on page 3411. The selectivity and orthogonality of the chosen protein immobilization schemes allows for forming parallel and orthogonal overlapping gradients of multiple proteins. This platform can be exploited to perform a wealth of cell-based assays on biomimetic surfaces.

Mater.ADVANCED MATERIALS, Issue 21 201021/2010) The cover shows the sophisticated surface design of the floating water fern Salvinia. The unique surface architecture is composed of complex hydrophobic eggbeater-shaped hairs with hydrophilic terminal cells. The evenly distributed hydrophilic patches stabilize the air layer by pinning the air/water interface in place. The paradox combination of hydrophilic patches on superhydrophobic surfaces (the "Salvinia Effect") provides an innovative concept for smart biomimetic surfaces in maritime coatings and underwater applications, as reported by Wilhelm Barthlott, Thomas Schimmel, and co-workers on p. 2325. [source] The Salvinia Paradox: Superhydrophobic Surfaces with Hydrophilic Pins for Air Retention Under WaterADVANCED MATERIALS, Issue 21 2010Wilhelm Barthlott A novel mechanism for long-term air retention under water is found in the sophisticated surface design of the water fern Salvinia. Its floating leaves are evenly covered with complex hydrophobic hairs retaining a layer of air when submerged under water. Surprisingly the terminal cells of the hairs are hydrophilic. These hydrophilic patches stabilize the air layer by pinning the air,water interface. This "Salvinia Effect" provides an innovative concept to develop biomimetic surfaces with long-term air-retention capabilities for under water applications. [source] Bone morphogenetic proteins in tissue engineering: the road from laboratory to clinic, part II (BMP delivery)JOURNAL OF TISSUE ENGINEERING AND REGENERATIVE MEDICINE, Issue 2-3 2008P. C. Bessa Abstract Bone morphogenetic proteins (BMPs) are cytokines with a strong effect on bone and cartilage growth and with important roles during embryonic patterning and early skeletal formation. BMPs have promising potential for clinical bone and cartilage repair, working as powerful bone-inducing components in diverse tissue-engineering products. Synthetic polymers, natural origin polymers, inorganic materials and composites may be used as carriers for the delivery of BMPs. Carriers range from nanoparticles to complex three-dimensional (3D) scaffolds, membranes for tissue-guided regeneration, biomimetic surfaces and smart thermosensitive hydrogels. Current clinical uses include spinal fusion, healing of long bone defects and craniofacial and periodontal applications, amongst others. BMP-2 and BMP-7 have recently received approval by the US Food and Drug Administration (FDA) for specific clinical cases, delivered in absorbable collagen sponges. Considering the expanding number of publications in the field of BMPs, there are prospects of a brilliant future in the field of regenerative medicine of bone and cartilage with the use of BMPs.

Cover: Glow discharges can modify surface chemistry and morphology of materials, and can be applied directly on living tissues and cells, in order to orient their biological response. Functional biomimetic surfaces, sterilization and decontamination, patterning/structuring procedures, non fouling coatings and other features can be delivered today by this technology in an increasing number of applications in Biology and Medicine.
