The lack of biosafety and insufficient delivery efficiency of gene-carriers are still obstacles to human gene therapy. This paper reported highly biocompatible chitosan (CS) functionalized Prussian blue (PB) nanoparticles (designated as CS/PB NPs) for photocontrollable gene delivery. The ultra-small size (∼3 nm), positive charge and high physiological(More)
OBJECTIVE To prepare a lymph node-targeted ultrasound/fluorescence bi-functional imaging contrast agents, and observe its effectiveness both on contrast-enhanced ultrasound (CEUS) and vivo near infrared fluorescence (NIR) imaging through animal experiments. METHODS The chimeric lymph node-targeted ligand (phosphatidylserine) and near-infrared fluorescent(More)
The present training method of support vector machine has large computational cost. Integrating SVM’s geometrical interpretation and structural risk minimization, a new fast support vector machine: Centroid Normal Direct Support Vector Machine (CNDSVM) was proposed. The normal vector of optimal separating hyperplane was determined by the connective(More)
Objective: Photoacoustic (PA) tomography (PAT) has attracted extensive interest because of its optical absorption contrast and ultrasonic detection. This study aims to develop a biocompatible and biodegradable PA contrast agent particularly promising for clinical applications in human body. Methods: In this study, we presented a PA contrast agent: 1,(More)
Biosurfactant-facilitated oil recovery is one of the most important aspects of microbial enhanced oil recovery (MEOR). However, the biosurfactant production by biosurfactant-producing microorganisms, most of which are aerobes, is severely suppressed due to the in-situ anoxic conditions within oil reservoirs. In this research, we successfully engineered a(More)
