Hi everyone, I’m a researcher working on ship hydrodynamics and biofouling. We recently finished a study titled 'Spatial and Taxonomic Variability of Biofouling on Purse Seiners Moored in Different Ports.' We looked at commercial fishing vessels that were essentially clones—same ship type, same antifouling coating, and similar operational profiles. The results were surprising: despite the similarities, the biofouling patterns (barnacles, slime, algae) were completely different based solely on the specific port they were moored in. It highlights how local environmental factors can override the quality of the paint or the design of the ship. For the boat owners here: Have

In this review study, we look at how nanomaterials can prevent biofouling in marine antifouling coatings, which have a significant influence on maritime vessels and structures. Nanomaterials with wide...

A biocompatible, all-polymeric MNEs designed for long-term ECG monitoring is developed. Coated with PEDOT:Tos and zwitterionic SBMA, the MNEs offer ultra-low impedance and antifouling properties. After 14 days of continuous use, the MNEs accurately detected PQRST complexes, highlighting its potential for long-term, real-time ECG monitoring in everyday life. Abstract Cardiovascular disease demands reliable long-term monitoring for early and accurate diagnosis. While conventional gel electrodes are commonly utilized for monitoring electrocardiogram (ECG) signals, they have limitations, such as dehydration-induced signal degradation and motion artifacts, hindering their effectiveness for continuous long-term use. To address these issues, this study develops a biocompatible and all-polymeric microneedle electrode (MNE) optimized for stable ECG monitoring over extended periods. The MNE surface is sequentially coated with poly(3,4-ethylenedioxythiophene):tosylate (PEDOT:Tos) to reduce the interfacial impedance (0.63 kΩ∙cm 2 at 10 Hz), followed by zwitterionic sulfobetaine methacrylate (SBMA) to prevent nonspecific protein adsorption and cellular adhesion (84.2% and 98.6% reduction in E. coli and BSA, respectively). Moreover, the SBMA-coated MNE demonstrates excellent mechanical strength, allowing it to penetrate human skin without deformation, as verified by optical coherence tomography and insertion-force assessments. In practical applications using a wireless wearable ECG monitoring system, the SBMA-coated MNE consistently captures high-quality ECG signals over a 14-day period, significantly outperforming gel electrodes under dynamic movement conditions.
