Abstract
![]()
Many dynamic interactions within the cell microenvironment
modulate
cell behavior and cell fate. However, the pathways and mechanisms
behind cell–cell or cell–extracellular matrix interactions
remain understudied, as they occur at a nanoscale level. Recent progress
in nanotechnology allows for mimicking of the microenvironment at
nanoscale in vitro; electron-beam lithography (EBL)
is currently the most promising technique. Although this nanopatterning
technique can generate nanostructures of good quality and resolution,
it has resulted, thus far, in the production of only simple shapes
(e.g., rectangles) over a relatively small area (100 × 100 μm),
leaving its potential in biological applications unfulfilled. Here,
we used EBL for cell-interaction studies by coating cell-culture-relevant
material with electron-conductive indium tin oxide, which formed nanopatterns
of complex nanohexagonal structures over a large area (500 ×
500 μm). We confirmed the potential of EBL for use in cell-interaction
studies by analyzing specific cell responses toward differentially
distributed nanohexagons spaced at 1000, 500, and 250 nm. We found
that our optimized technique of EBL with HaloTags enabled the investigation
of broad changes to a cell-culture-relevant surface and can provide
an understanding of cellular signaling mechanisms at a single-molecule
level.

Abstract
Anatomically, the human tooth has structures both embedded within and forming part of the exterior surface of the human body. When a tooth is lost, it is often replaced by a dental implant, to facilitate the chewing of food and for esthetic purposes. For successful substitution of the lost tooth, hard tissue should be integrated into the implant surface. The microtopography and chemistry of the implant surface have been explored with the aim of enhancing osseointegration. Additionally, clinical implant success is dependent on ensuring that a barrier, comprising strong gingival attachment to an abutment, does not allow the infiltration of oral bacteria into the bone-integrated surface. Epithelial and connective tissue cells respond to the abutment surface, depending on its surface characteristics and the materials from which it is made. In particular, the biomechanics of the implant-abutment connection structure (i.e., the biomechanics of the interface between implant and abutment surfaces, and the screw mechanics of the implant-abutment assembly) are critical for both the soft tissue seal and hard tissue integration. Herein, we discuss the clinical importance of these three interfaces: bone-implant, gingiva-abutment, and implant-abutment.

Abstract
Development of biocompatible polymeric systems capable of cell adhesion and proliferation is a challenging task. Proper cross-linking of small cell adhesive peptide sequences is useful in this respect as it provides the inherent nontoxic environment as well as the cross-linked polymeric network to the cells for adhesion and proliferation. A multiple cross-linking strategy is applied to create a peptide-based cross-linked polymer. Covalent linkage through disulfide bond formation, supramolecular linkage using homoternary complexation by CB[8], and enzymatic cross-linking by HRP-mediated dimerization of tyrosine are used to prepare the cross-linked, peptide-based polymer decorated with cell-adhesive RGDS sequence. The supramolecular cross-linking via CB[8] provided stability as well as brings the RGDS sequences at the surface of the polymer particles. The order of cross-linking allowed to fine-tune the particle size of the polymer and polymer particles of wide range (200-1000 nm) can be prepared by varying the order. The cross-linked polymer particles (P1 and P2) were found to be stable at wide range of temperature and pH. Moreover, as intended, the polymer was noncytotoxic in nature and showed efficient cell adhesion and proliferation property, which can be used for further biological applications.

Abstract
Titanium (Ti) plays a predominant role as the material of choice in orthopaedic and dental implants. Despite the majority of Ti implants having long-term success, premature failure due to unsuccessful osseointegration leading to aseptic loosening is still too common. Recently, surface topography modification and biological/non-biological coatings have been integrated into orthopaedic/dental implants in order to mimic the surrounding biological environment as well as reduce the inflammation/infection that may occur. In this review, we summarize the impact of various Ti coatings on cell behaviour both in vivo and in vitro. First, we focus on the Ti surface properties and their effects on osteogenesis and then on bacterial adhesion and viability. We conclude from the current literature that surface modification of Ti implants can be generated that offer both osteoinductive and antimicrobial properties.
