Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

FlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...

Isolation of Methoxyfuranocoumarins FromAmmi majusby Centrifugal Partition Chromatography [PDF]

Journal of Chromatographic Science, 2015
Pure methoxyfuranocoumarins were isolated from Ammi majus L. by use of low-pressure column chromatography (LPCC) followed by centrifugal partition chromatography (CPC). The concentrated petroleum ether extract from fruits of A. majus was fractionated on a silica gel column using a gradient of ethyl acetate in dichloromethane (0-80%, v/v). Coumarin-rich

Capture of adeno‐associated viruses from clarified lysate by continuous flow ultracentrifugation: a comparative study of iodixanol and sucrose gradients

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Adeno‐Associated Virus vectors are widely used in gene therapy due to their safety and efficacy. Despite the interest in their therapeutical application, AAV purification remains a significant challenge. Density gradient ultracentrifugation using cesium chloride, sucrose, or iodixanol gradients are common methods for AAV ...
