NN researchers Jan Grzelak, Martí Gich, Anna Roig and Juan Pellico have published a new article in the journal Dalton Trans. The study has been carried out in close collaboration with Rafael T. M. Rosales, from the King's College London.

The study reveals that microparticles with similar size but different shapes do not travel through the body in the same manner. By using PET imaging, this NN-led team discovered that rod-shaped microparticles exit the bloodstream more quickly and concentrate in more in the lungs than spherical particles that primarily accumulate in the liver and spleen. This shape-dependent behaviour could guide the design of new drug delivery systems.

Pushing bacterial cellulose into a transformative product for wearable sensor applications! Our biosynthesised nanocellulose is used here for the first time as a substrate enabling the screen printing of electrochemical sensors for real-time, non-invasive alcohol monitoring in sweat. The bacterial cellulose sweat alcohol sensor has a highly linear response to alcohol concentration in human sweat, with a minimum detection concentration of 5mM and excellent reproducibility. In addition to sustainability, it shows excellent biocompatibility and self-adhesion. The sensor’s bidirectional functionality also opens new avenues for innovative sweat-sensing system designs.

Eco-Friendly Conformal and Self-Adhesive Electrochemical Sensors for Sweat Monitoring is a new paper by NN researchers Xiaohe Wang, Muling Zeng, Mabel Torrens, Martí Gich, and Anna Roig. It has been published in the journal ACS Applied Materials & Interfaces. This research was done in close collaboration with Pengfei Niu (Tianjin University) and César Fernández Sánchez (IMB-CNM and CIBER-BBN).

Naureen Khanam, Nico Dix, Ana Vila Costa and Martí Gich have co-authored a new paper in the Journal of the American Chemical Society (JACS). The study demonstrates a new strategy for synthesising high-aspect-ratio ε-Fe₂O₃ nanorods using rare-earth silicates as high-temperature surfactants. This approach allows precise control of the nanocrystals’ shape and growth, overcoming limitations of previous methods and opening new possibilities to explore the magnetic properties of this metastable iron oxide phase.
