Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Evidence for a novel Chlorella virus-encoded alginate lyase [PDF]
To clone the genes encoding lysis protein from a Chlorella virus, water samples were collected from 13 aquatic environments located in the Kanto area of Japan. Eight water samples contained plaque-forming viruses on Chlorella sp. NC64A, but no virus was detected in the other five samples.

Understanding aspects of alginate biosynthesis and regulation by Pseudomonas aeruginosa : a thesis presented in partial fulfilment of the requirements of the degree of Doctor of Philosophy in Microbiology at Massey University, Palmerston North, New Zealand [PDF]
Alginate is a medically and industrially important polymer produced by seaweeds and certain bacteria. The bacterium Pseudomonas aeruginosa over-produces alginate during cystic fibrosis lung infections, forming biofilms, making the infection difficult to ...

Microarchitecture sculpting via phase separation programs hydrogel mechanics by creating globular, inverse globular, and spinodal structures. Spinodal architectures deliver superior toughness and energy dissipation, while ionic modulation through single polymer phase separation offers a simple, scalable route to tune mechanical properties ...

A mechanically tunable ECM platform is created by integrating dECM–alginate matrices with in‐bath tumor printing. The mechanically tunable ECM environment drives tumors to acquire hypoxia, mechanotransduction signaling, metastatic traits, and drug‐resistant phenotypes that collectively promote malignant transformation.

This study develops a hydrogelation method for preparing hydrogels from precursors containing polymer‐PBA and HRP via H2O2‐triggered deboronation and subsequent enzymatic crosslinking. This hydrogelation method can impart dynamic properties to HRP‐mediated hydrogelation without any additives, thereby demonstrating the potential of this hydrogelation ...

Comparative characterization of three bacterial exo-type alginate lyases [PDF]
Alginate, a major acidic polysaccharide in brown macroalgae, has attracted attention as a carbon source for production of ethanol and other chemical compounds. Alginate is monomerized by exo-type alginate lyase into an unsaturated uronate; thus, this enzyme is critical for the saccharification and utilization of alginate.
