A two-phase and long-lasting multi-antibacterial coating enables titanium biomaterials to prevent implants-related infections

Materials Today Bio, 2022
In clinical work, the main challenges for titanium (Ti) implantation are bacterial infection and aseptic loosening, which severely affect the survival rate of implants. The first 4 weeks post-operation is the infection peak phase of implants.

From bi-layer to tri-layer Fe nanoislands on Cu3Au(001)

, 2001
Self assembly on suitably chosen substrates is a well exploited root to control the structure and morphology, hence magnetization, of metal films. In particular, the Cu3Au(001) surface has been recently singled out as a good template to grow high spin Fe

Self-replication and evolution of DNA crystals [PDF]

, 2005
Is it possible to create a simple physical system that is capable of replicating itself? Can such a system evolve interesting behaviors, thus allowing it to adapt to a wide range of environments?

Investigation of the effects caused by applying voltage in Layer-by-Layer self-assembly method

MATEC Web of Conferences, 2013
Recently, Layer-by-Layer (LbL) self-assembly method under applied voltage (voltage-applied LbL) attracts great attention. It is reported that the method enables more abundant film adsorption than conventional LbL method.

Layer-by-layer self-assembly of supramolecular and biomolecular films

Reviews in Molecular Biotechnology, 2002
In this paper, we give a short account on recent studies of layer-by-layer self-assembly of supramolecular and biomolecular films. Such films are built up from layers of macro-ions with opposing charge. A simple film can be obtained by alternating the adsorption of two components: a flexible, synthetic polycation chains and a supramolecular or ...
