Research Interest  

Biographical Sketch

         The main research focus of Principal Investigator can be classified into two categories: firstly, development of a fiber-optic platform, which is disposable, minimally invasive, and can provide simultaneously in vivo monitoring of various analytes up to several weeks [1,2,4-7,9,10,11] and in vivo personalized (tunable) delivery of therapeutic agents [3]; secondly, designs of contrast agents of medical imaging for clinical conditions, lesion malignancy screening [5,12] and contrast media induced nephropathy prevention [5].  
          The biocompatibility of the fiber-optic sensor platform was verified in animal models, and the fabrication procedure was optimized for the capability in industrial mass scale production [7,9,10]. The 1st application of the sensor platform is a glucose sensor, which can be integrated into an “artificial pancreas” consisting of an insulin pump and close-loop algorithm as the signal input of the feedback control. The preliminary results of accuracy agreement analysis from canine study implied the potential of the sensor for clinical applications [4]. The 2nd application is to trigger in vivo topical release of photo-thermal responsive liposome (incorporation of hydrophobic gold nanoparticles in a temperature-responsive liposome) [3]. The therapeutic effect from the vesicle delivering anti-cancer agent can by quantified immediately with the scrambling of membrane phosphatidylserine in apoptotic cancer cells by the fiber-optic platform, aiming as the personalized chemotherapy system [1,2,6]. The immediate evaluation of chemotherapy effect by early apoptotic reaction has the potential for significant clinical benefits in improving efficacy and reducing adverse events.
       For improving lesion diagnosis with medical imaging, we established a xenograft model demonstrating essential clinical properties of malignant and benign lesions [12]. The animal model was applied in characterizing the diagnosis outcomes of lesion malignancy screening and delineation from several customized contrast agents. diglucosamid-SIDAG, a custom-made NIR fluorophore, exhibited “delayed wash-out contrast” in cancer tissue, which can be applied in lesion malignancy indication and delineation of tumor margin. The encapsulation of conventional CT (computed tomography scan) contrast agent in long-circulating liposome was found to improve the diagnosis accuracy and specificity in the animal model and could also eliminate the contrast media induced nephropathy [5].
