Pluripotent stem cells (PSCs) possess the extraordinary capability to differentiate into a variety of cell types. This capability is tightly regulated by epigenetic mechanisms, particularly histone modifications. Moreover, the reprogramming of somatic or fate-committed cells into induced pluripotent stem cells (iPSCs) largely relies on these modifications, such as histone methylation and acetylation of histones. While extensive research has been conducted utilizing mouse models, the significance of histone modific…

Dynamic DNA nanotechnology creates programmable reaction networks and nanodevices by using DNA strands. The key reaction in dynamic DNA nanotechnology is the exchange of DNA strands between different molecular species, achieved through three- and four-way strand exchange reactions. While both reactions have been widely used, the four-way exchange reaction has traditionally been slower and less efficient than the three-way reaction. In this paper, we describe a new mechanism to optimize the kinetics of the four-way…

Nanodiamond – functionalised with oligoglycine – is used as a novel Pickering emulsion stabiliser, offering high retention on bovine cornea tissue via mucoadhesion.

Abstract Information propagation by sequence-specific, template-catalyzed molecular assembly is the source of the biochemical complexity of living systems. Templating allows the production of thousands of sequence-defined proteins from only 20 distinct building blocks. By contrast, exploitation of this powerful chemical motif is rare in non-biological contexts, particularly in enzyme-free environments, where even the template-catalyzed formation of dimers is a significant challenge. The main obstacle is product in…
