Dental implant failure often occurs due to oral bacterial infection. The aim of this study was to demonstrate that antibiotic efficacy could be enhanced with modified titanium. First, the titanium was modified by anodization and heat-treatment. Then, a biomimetic coating process was completed in two steps. Surface characterization was performed with scanning electron microscopy, energy dispersi...

We present a straightforward approach with high moldability for producing dual-responsive and multi-functional plasmonic hydrogel valves and biomimetic architectures that reversibly change volumes and colors in response to temperature and ion variations. Heating of a mixture of hybrid colloids (gold nanoparticles assembled on a hydrogel colloid) and hydrogel colloids rapidly induces (within 30 ...

Biomimetic swimming devices that employ compliant mechanisms have shown promise as an alternative to current biomimetic design approaches that involve the use of complex mechanisms. The additional stealth, ruggedness, and efficiency of this approach means that such devices could perform important tasks such as reconnaissance and underwater mapping. Many of these applications also require high l...

A biomimetic acoustic sensor was fabricated with single crystal PMN-PT piezoelectric cantilever array that can mimic functional properties of mammalian cochlea. Basilar membrane of mammalian cochlea can separate frequency components of input sound source and Ion channel phenomenon of hair cells on basilar membrane can generate action potentials for stimulating a nerve site. The piezoelectric ca...

BACKGROUND The resistance of Helicobacter pylori to the antibiotic therapy poses the problem to discover new therapeutic approaches. Recently it has been stated that antibacterial, immunomodulatory, and antioxidant properties of lactoferrin are increased when this protein is surface-linked to biomimetic hydroxyapatite nanocrystals. OBJECTIVE Based on these knowledge, the aim of the study was ...

One of the most significant challenges facing the biomimetic synthesis of materials is achieving the requisite level of dimensional and spatial control. Typical reaction conditions for biomimetic silica synthesis allow for continued growth and ripening leading to the formation of larger nanospheres on the order of 200-600 nm in diameter. Herein, we have used polyamidoamine and polypropylenimine...

Biomimetic robotic fish is a new type of underwater robot with many superior characteristics such as high movement speed, high motion efficiency, high energy efficiency, and so on. However, the traditional kinematic model for biomimetic robotic fish has many shortcomings which limit their movement speed, such as the rigid shakes of the fish’s head when it swims, which is caused by neglecting th...

This mentor presentation displays how Team Genius mentors teach concepts through the process of reverse engineering. It examines the current applications of reverse engineering to teach both a scientific concept, in this case, biomimetics, and engineering concepts. To begin, we will describe existing robots and prototypes—from research labs of Stanford University and the Massachusetts Institute...

Microstructural characteristics and biocompatibility of a Type-B carbonated hydroxyapatite (HA) coating prepared on NiTi SMA by biomimetic deposition were characterized using XRD, SEM, XPS, FTIR and in vitro studies including hemolysis test, MTT cytotoxicity test and fibroblasts cytocompatibility test. It is found CO(3)(2-) groups were present as substitution of PO(4)(3-) anions in HA crystal l...

Biomimetics is a rapidly developing discipline and has been suggested applicable in machine vision and image processing because human vision system has almost evolved to be perfect. Previously proposed BA+DRF method is a biomimetic image processing method which improves images quality effectively on the basis of the brightness adaption and disinhibitory properties of concentric receptive field ...
