Evolution of the African Tigerfish (Genus Hydrocynus) : phylogeographic insights into drainage evolution

open access: yes, 2010
Aquatic species,notably fish, can reveal details of drainage evolution, especially where their evolutionary relationships can be reconstructed using phylogeographic methods. In this study, the mitochondrial DNA sequence diversity of the characiform genus, Hydrocynus, which is widespread across tropical Africa, is reconstructed using a phylogenetic ...

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Remote‐Controllable Immune‐Priming Spot Formation Via Nanocomplexed Hydrogel‐Assisted Histotripsy: Immunoasis

open access: yesAdvanced Materials, EarlyView.
A novel immunotherapeutic strategy combines injectable, adjuvant‐loaded hydrogels with externally controlled histotripsy to create immune‐priming sites within tumors. This approach generates millimeter‐sized immune‐activated lesions with flexible, patient‐tailored treatment scheduling, enabling precise immune activation through tumor ablation‐mediated ...

Stiff to Soft: A Protein‐Based Buffer Layer for Improving the Long‐Term Performance of Microneedle Sensors

open access: yesAdvanced Materials, EarlyView.
To enhance stability and long‐term biocompatibility of wearable microneedle sensors, a crosslinking‐recombination bovine serum albumin material is used as a buffer layer coated on microneedle sensors. This coating layer possesses a unique stiff‐to‐soft transition function balancing the mechanical stiffness desired for puncturing and soft required for ...
