TitleSpectroscopy for nanomaterials and bio-medical applications

AbstractSpectroscopy is an old technique for study molecular structure. The non-contact, non-invasive nature with advances in instrumental design; spectroscopy and microscopy have become powerful tools for study nanomaterials and biological systems. This talk will be focused on Infrared and Raman spectroscopy, and the applications of nanodiamond for bio medical studies, especially bio imaging and (cancer) drug delivery.

Nanometer-size diamond particles, first synthesized in 1963, exhibit remarkable potential in diverse areas of research owing to their unique physical, optical and surface chemical properties. Properties such as intense luminescence without photo-bleaching, high surface area and adaptive chemical reactivity, and non-cytotoxicity make nanodiamond (ND) attractive in various biomedical applications such as drug delivery, imaging or bio-labeling etc. However, for optimal and specific drug or biomolecule loading, interactions and stability on diamond surface are still challenging tasks due to surface inhomogeneity and contaminations. The complex nature of nanodiamond surfaces are possible to further conjugate clinical drug for specific targeted delivery. The composed ND-X complexes are demonstrated in a 3D cellular model (multicellular tumor spheroid, MCTS), consisted of large collection of cells in a three dimensional format extend about 0.7 mm in diameter ; resemble the configuration of a tumor, ideal for evaluating the efficacy of drug delivery using a ND-drug complex.

單位簡介

本系的重點研究領域包括:凝態物理、光電與奈米科學、高能與粒子物理、軟凝態物理與生物物理、原分子光學物理、及物理科學教育等。本系前身為臺灣省立師範學院理化系物理組,成立於民國三十五年(1946年)本校創校之始。民國五十一年(1962年)本系獨立成系,民國六十三年(1974年)成立物理研究所碩士班,民國八十年(1991年)成立研究所博士班。長久以來,本系肩負著培育臺灣中等學校物理科師資的重任,但也不忘在物理學術研究上求新求進步。至今本系培育出的學術人才已有一位中研院院士及近百位中研院研究員及大學教授,各行各業的高科技人材更是不勝枚舉。民國八十三年師資培育法改制後,本系已升級為尖端學術研究、科技應用研發、及中學師資培育三者齊備的系所。
