Advanced Healthcare Materials, EarlyView.Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Advanced Healthcare Materials, EarlyView.Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

Atomic Structures of all the Twenty Essential Amino Acids and a Tripeptide, with Bond Lengths as Sums of Atomic Covalent Radii [PDF]
arXiv, 2008 Recently, the bond lengths of the molecular components of nucleic acids and of caffeine and related molecules were shown to be sums of the appropriate covalent radii of the adjacent atoms. Thus, each atom was shown to have its specific contribution to the bond length. This enabled establishing their atomic structures for the first time.

Self-assembled antibody multimers through peptide nucleic acid conjugation.
Journal of the American Chemical Society, 2013 With the recent clinical success of bispecific antibodies, a strategy to rapidly synthesize and evaluate bispecific or higher order multispecific molecules could facilitate the discovery of new therapeutic agents. Here, we show that unnatural amino acids

Molecular structure and interactions of nucleic acid components in nanopaticles: ab initio calculations [PDF]
Ukrainian Journal of Physics, 2012, Vol. 57, no. 7, pp. 723-731, 2012 Self-associates of nucleic acid components (stacking trimers and tetramers of the base pairs of nucleic acids) and short fragments of nucleic acids are nanoparticles (linear sizes of these particles are more than 10 A. Modern quantum-mechanical methods and softwares allow one to perform ab initio calculations of the systems consisting of 150-200 atoms ...
