Aim: This case report describe a resin layering restorative technique based on biomimetic concept to improve esthetics in a patient with dental defects that affected both enamel and dentin in anterior teeth.
Background: Severe structural defect in anterior teeth compromises esthetics and it is a high challenge to become the defect imperceptible after the restoration.
Case Description: A clinical sequence of applying different composite resin layers allowed the reproduction of the interaction between hard dental tissues and the restorative material.
Conclusion: This technique achieved a satisfactory final esthetic outcome, preserving sound teeth structure and at same time, improved the quality of life of the young patient.
Clinical Significance: The utilization of the biomimetic concept to increase a disharmonic smile with dental defects is based in a conservative approach, which reached a satisfactory and esthetic outcome.

Prokaryotic microorganisms, comprising and , exhibit a fascinating diversity of cell envelope structures reflecting their adaptations that contribute to their resilience and survival in diverse environments. Among these adaptations, surface layers (S-layers) composed of monomolecular protein or glycoprotein lattices are one of the most observed envelope components. They are the most abundant cellular proteins and represent the simplest biological membranes that have developed during evolution.

Lubrication surfaces reduce the risk of cross-contamination and enhance the long-term stability of medical devices, which holds significance in the realm of antifouling medical materials. However, the complexity of constructing micronano structures to immobilize lubricating fluids and the fluorine content typically found in silane coupling agents restrict their widespread adoption. In this study, we prepared a biomimetic lubricating coating (BLC) through the one-step self-assembly of octadecyltrichlorosilane and oil infusion.

Endowing biomimetic sequence-controlled polymers with chiral functionality to construct stimuli-responsive chiral materials offers a promising approach for innovative chiroptical switch, but it remains challenging. Herein, it is reported that the self-assembly of sequence-defined chiral amphiphilic alternating azopeptoids to generate photo-responsive and ultrathin bilayer peptoidosomes with a vesicular thickness of ≈1.50 nm and a diameter of around ≈290 nm.

mRNA-based vaccines against the COVID-19 pandemic have propelled the use of nucleic acids for drug delivery. Conventional lipid-based carriers, such as liposomes and nanolipogels, effectively encapsulate and deliver RNA but are hindered by issues such as premature burst release and immunogenicity. To address these challenges, cell membrane-coated nanoparticles offer a promising alternative.

The concept of genetic code expansion (GCE) has revolutionized the field of chemical and synthetic biology, enabling the site-specific incorporation of noncanonical amino acids (ncAAs) into proteins, thus opening new avenues in research and applications across biology and medicine. In this review, we cover the principles of GCE, including the optimization of the aminoacyl-tRNA synthetase (aaRS)/tRNA system and the advancements in translation system engineering. Notable developments include the refinement of aaRS/tRNA pairs, enhancements in screening methods, and the biosynthesis of noncanonical amino acids.
