Transparent aerogels of biopolymer–polysiloxane double networks have been developed. In their Research Article (e202306518), Satoru Takeshita and Takumi Ono established a sequential protocol for condensation methyltrimethoxysilane crosslinking various biopolymers such as alginate, carrageenan, pectin, carboxymethyl cellulose in the same space. The drawbacks or polysiloxane alone can be overcome...

UNLABELLED New developments on biomaterials are important in surgery. The behavior of a new membrane produced from sugarcane will be evaluated in the middle ear of rats. AIM This study analyzed the results from the interaction of the sugarcane-base biopolymer membrane in the middle ear of a rat. MATERIALS AND METHODS We ran an experimental, prospective, paired study with 24 Wistar rats. The...

This study investigated the in vitro acid-induced gelation of mixed systems of two biopolymers; low acyl and high acyl gellan gum. Rheological and texture analysis showed that these mixed gels displayed textures that lay between the material properties exhibited for the low and high acyl variants. DSC analysis showed that mixtures of the low acyl and high acyl forms exhibit two separate conform...

Implant-associated surgical-site infections can have significant clinical consequences. Previously we reported a method for prophylactically disinfecting implant surfaces in surgical pockets, where an antibiotic solution containing minocycline (M) and rifampin (R) was applied as a solid film in a crosslinked biopolymer matrix that partially liquefied in situ to provide extended prophylaxis. Her...

We describe the engineering of reversible fluorescence photoswitching in DNA with high-density substitution, and its applications in advanced fluorescence microscopy methods. High-density labeling of DNA with cyanine dyes can be achieved by polymerase chain reaction using a modified DNA polymerase that has been evolved to efficiently incorporate Cy3- and Cy5-labeled cytosine base analogues into...
