This study examined changes in elastic modulus, mineral density and ultrastructure of resin-infiltrated dentin after biomimetic remineralization. Sixty demineralized dentin beams were infiltrated with Clearfil Tri-S Bond, One-Step or Prime&Bond NT. They were immersed in simulated body fluid (SBF) for 1 week to maximize water sorption before determining the baseline elastic moduli. For each adhe...

We propose to combine a biomimetic navigation model which solves a simultaneous localization and mapping task with a biomimetic sonar mounted on a mobile robot to address two related questions. First, can robotic sonar sensing lead to intelligent interactions with complex environments? Second, can we model sonar based spatial orientation and the construction of spatial maps by bats? To address ...

This review describes recent developments in the emerging field of biomimetic polymeric biomaterials, which signal to cells via biologically active entities. The described biological effects are, in contrast to many other known interactions, receptor mediated and therefore very specific for certain cell types. As an introduction into this field, first some biological principles are illustrated ...

Composite sandwich structural joints, such as T-joints, are used in many different composite applications to transfers the load orthogonally between two sandwich elements. However, these joints connecting the sections can represent the weakest link in sandwich composite structures due to the lack of reinforcement in the out-of-plane direction. Therefore, this paper presents a new methodology fo...

Biological olfactory and taste systems are natural chemical sensing systems with unique performances for the detection of environmental chemical signals. With the advances in olfactory and taste transduction mechanisms, biomimetic chemical sensors have achieved significant progress due to their promising prospects and potential applications. Biomimetic chemical sensors exploit the unique capabi...

In contrast to a biomimetic electrophilic cyclisation cascade, we employ a contra-biomimetic nucleophilic cyclisation cascade to give the tricyclic core of 4-hydroxy-GR24 in a single step. Kinetic resolution using a stereoselective Noyori transfer hydrogenation enables the concise synthesis of any enantiomerically enriched 4-hydroxy-GR24 stereoisomer.

A series of tunable and regenerable biomimetic hydrogen sources, 4,5-dihydropyrrolo[1,2-a]quinoxalines, have been synthesized and applied in biomimetic asymmetric hydrogenation of 3-aryl-2H-benzo[b][1,4]oxazines and 1-alkyl-3-aryl-quinoxalin-2(1H)-ones, providing the chiral amines with up to 92% and 89% ee, respectively.

It is the mission of this design team to design a viable Mars explorer with biomimetic inspiration, with specific regard to the locomotion system. The vehicle must have the capability to transport a payload that can aid in the search for life on Mars, as well as provide proof of biomimetic methods in physical and control system design.

This research is linked to the FET funded iCHEM project (session 76 Talking with Chemicals: Challenges of Biomimetic Infochemical Communication). In this communication we describe the development of a heterologous expression system, expressing insect olfactory receptors in Sf9 cells, which will be implemented in a surface acoustic wave (SAW) biomimetic sensor.
