Perfluorohexane sulfonic acid (PFHxS), one of the substitutes for perfluorooctane (PFOS), has been widely discussed around world. In this study, atmospheric concentrations PFHxS in Beijing summer and autumn 2021 were monitored, gas–particle partitioning wet dry deposition characteristics analyzed. The results show that average total 1.61 pg/m3 1.41 pg/m3, respectively. particulate fraction φ wa...

Dietary intake, age, gender, and body mass index were investigated as possible predictors of perfluorinated compounds in a study population from northern Norway (44 women and 16 men). In addition to donating a blood sample, the participants answered a detailed questionnaire about diet and lifestyle. Perfluorooctane sulfonate (PFOS) (29 ng/mL), perfluorooctanoate (PFOA) (3.9 ng/mL), perfluorohex...

Abstract Nanosized drug delivery systems have rapidly emerged as a promising approach to tumor therapy, which still many challenges in clinical application. In this study, doxorubicin-loaded O-carboxymethyl chitosan/perfluorohexane nanodroplets (O-CS-DOX NDs) were synthesized and functionally tested an effective system vitro vivo. O-CS-DOX NDs with small size (159.6 nm) good doxorubicin encapsu...

Drug-delivery systems with a unique capability to respond to a given stimulus can improve therapeutic efficacy. However, development of such systems is currently heavily reliant on responsive polymeric materials and pursuing this singular strategy limits the potential for clinical translation. In this report, with a model system used for drug-release studies, we demonstrate a new strategy: how ...
