Molecular investigation of the phylogenetic placement of Kartalinia and a revision of Bituminaria (Fabaceae: Psoraleeae)

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Kartalinia was described to accommodate a single, obscure species, Psoralea acaulis, based on its unique morphology and karyology. No concerted molecular phylogenetic studies were available for this species at the time, and therefore its phylogenetic position was uncertain.

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

open access: yesAdvanced NanoBiomed Research, Volume 6, Issue 7, July 2026.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

Combining Supramolecular and Covalent Chemistry to Form Reinforced Fibrillar Network Hydrogels From Fibrinogen Derivatives

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 7, July 2026.
ABSTRACT Fibrin hydrogels provide a highly supportive environment for three‐dimensional cell growth and morphogenesis but are limited by insufficient stability to maintain their shape and mechanical integrity. To address this limitation, we developed a reinforced fibrin hydrogel incorporating photo‐crosslinked methacrylated fibrinogen (FibMA).
