Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

Drug Testing and Analysis, Volume 18, Issue 9, Page 1157-1162, September 2026.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.

Scalable and Controlled Production of Microalgae‐derived Extracellular Vesicles Using a Differential Tangential Flow Filtration Protocol

Journal of Extracellular Biology, Volume 5, Issue 9, September 2026.
This work presents a robust project design for the scalable production of extracellular vesicles, focusing on nanoalgosomes derived from microalgae. Careful parameter optimization within a filtration‐based process ensures consistent isolation while preserving the structural and functional integrity of the vesicles.

Structural and Physical Properties of Glutamic Acid Oligopeptide‐Modified Silk Fibroin

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
This study presents a strategy to change the structure and mechanical properties of silk fibroin films by introducing glutamic acid oligopeptides. The modification expands the inter‐sheet distance between β‐sheets, enhances flexibility, and alters enzymatic degradation behavior, demonstrating a viable approach for designing silk‐based materials with ...
