國立臺灣師範大學化學系座落於公館校區理學院大樓。本系成立於民國五十一年，最初僅設大學部。之後於民國六十三年、七十八年陸續成立化學研究所碩士班和博士班。本系教育目標旨在培養化學專業人才與中等學校自然及化學專業師資，授課著重理論及應用性。本系所現有師資為專任教授25人，另外尚有與中央研究院合聘教授3位，在分析、有機、無機及物理化學四個學門的基礎上發展跨領域之教學研究合作計畫。此外，本系另有助教13位，職技員工1位，協助處理一般學生實驗及行政事務。學生方面，大學部現實際共322人，碩士班現實際就學研究生共174人，博士班現實際就學共55人。
本系一向秉持著教學與研究並重，近年來為配合許多研究計畫的需求，研究設備亦不斷的更新。本系所的研究計畫大部分來自國科會的經費補助。此外，本系提供研究生獎助學金，研究生可支領助教獎學金（TA）、研究獎學金（RA）和部分的個別教授所提供的博士班學生獎學金（fellowships）。成績優良的大學部學生也可以申請獎學金。
本校圖書館藏書豐富，除了本部圖書館外，分部理學院圖書館西文藏書現有13萬餘冊，西文期刊合訂本有911餘種期刊，將近約3萬冊。此外，西文現期期刊約450種，涵蓋化學、生化、生物科技、材料及其他科學類等領域。目前本系各研究室連接校園網路，將館藏查詢、圖書流通、期刊目錄轉載等功能，納入圖書館資訊系統中，並提供多種光碟資料庫之檢索及線上資料庫如Science Citation Index，Chemical Citation Index，Chemical Abstracts，Beilstein，MDL資料庫與STICNET全國科技資訊網路之查詢。

Item Solution-Processable Pyrite FeS2 Nanocrystals for the Fabrication of Heterojunction Photodiodes with Visible to NIR Photodetection(Wiley-VCH Verlag, 2012-07-03) D.-Y. Wang; Y.-T. Jiang; C.-C. Lin; S.-S. Li; Y.T. Wang; Chia-Chun Chen; C.-W. ChenA heterojunction photodiode with NIR photoresponse using solution processable pyrite FeS2 nanocrystal ink is demonstrated which has the advantages of earth-abundance and non-toxicity. The device consists of a FeS2 nanocrystal (NC) thin film sandwiched with semiconducting metal oxides with a structure of ITO/ZnO/FeS2 NC/MoO3/Au, which exhibits an excellent photoresponse with a spectral response extended to NIR wavelengths of up to 1150 nm and a high photocurrent/dark current ratio of up to 8000 at -1 V under AM1.5 illumination (100 mW cm−2).Item Enhanced Infrared Light Harvesting of Inorganic Nanocrystal Photovoltaic and Photodetector on Graphene Electrode(American Institute of Physics, 2011-06-27) C.-C. Lin; D.-Y. Wang; K.-H. Tu; Y.-T. Jiang; M.-H. Hsieh; Chia-Chun Chen; C.-W. ChenWe demonstrate an enhancement of infrared light harvesting of inorganic PbSnanocrystalphotovoltaic and photodetectordevices based on the transparent grapheneelectrode. Due to high infrared transparency of the grapheneelectrode with respect to indium tin oxide (ITO), the infrared photoresponse of the graphene-based device is superior to the ITO-based counterpart, in spite of a higher sheet resistance of the grapheneelectrode. The outstanding infrared characteristics of the devices based on the grapheneelectrode make it a promising candidate for infrared optoelectronic applications such as solar cells, imaging and sensing, or optical communication.Item A Triantennary Dendritic Galactoside-Capped Nanohybrid with a ZnS/CdSe Nanoparticle Core as a Hydrophilic, Fluorescent, Multivalent Probe for Metastatic Lung Cancer Cells(Wiley-VCH Verlag, 2008-02-22) C.-T. Chen; Y.-S. Munot; S.-B. Salunke; Y.-C. Wang; R.-K. Lin; C.-C. Lin; Chia-Chun Chen; Y-H. LiuA new tri-antennary, galactoside-capped gallamide dendritic anchor with thiolate focal group is synthesized via click chemistry. The highly hydrophilic dendron was efficiently anchored onto the surface of CdSe/ZnS core/shell nanoparticles in a covalent fashion, as evidenced by 1H NMR spectrum of the resultant nanohybrid with intact core fluorescent property. The water-soluble nano-hybrid was found smoothly and selectively uptaken by lung cancer cells enriched with membrane-bound asialoprotein receptors in 2–3 h, as evidenced by confocal microscopic analysis. Furthermore, cancer cells that are undergoing active mitosis also tend to uptake the nanohybrids efficiently and remain sustainable in serum-containing medium for several days, which shed light on its application as a photodynamic drug carrier for apoptosis study.Item Globotriose-Functionalized Gold Nanoparticles as Multivalent Probes for Shiga-like Toxin(Wiley-VCH Verlag, 2008-05-05) Y.-Y. Chien; M.-D. Jan; A.-K. Adak; H.-C. Tzeng; Y.-P. Lin; Y.-J. Chen; K.-T. Wang; C.-T. Chen; Chia-Chun Chen; C.-C. LinCompared to monovalent carbohydrates, multivalent carbohydrate ligands exhibit significantly enhanced binding affinities to their interacting proteins. Here, we report globotriose (Pk ligand)-functionalized gold nanoparticle (AuNP) probes for the investigation of multivalent interactions with the B5 subunit of Shiga-like toxin I (B-Slt). Six Pk-ligand-encapsulated AuNPs (Pk-AuNPs) of varying particle size and linker length were synthesized and evaluated for their potential as multivalent affinity probes by using a surface plasmon resonance competition assay. The affinity of these probes for the interacting proteins was greatly affected by nanoparticle size, linker length, and ligand density on nanoparticle surface. For example, the 20-nm 20-Pk-l-AuNP, which had a relatively long linker showed a >108-fold increase in affinity compared with the mono Pk ligand. This intrinsic high-affinity AuNP probe specifically captured the recombinant B-Slt from Escherichia coli lysate, and the resulting purity of the B-Slt was >95 %. We also developed a robust Pk-AuNP-based detection method for Slt-I by combining the technique with silver enhancement.Item Selective Binding of Mannose-Encapsulated Gold Nanoparticles to Type I Pili in Escherichia Coli(American Chemical Society, 2002-04-10) C.-C. Lin; Y.-C. Yeh; C.-Y. Yang; C.-L. Chen; G.-F. Chen; Chia-Chun Chen; Y.-C. WuThe synthesis, characterization and biological application of mannose encapsulated gold nanoparticles (m-AuNP) are reported. m-AuNP is well dispersed and very stable without aggregation in the media of broad ion strength and pH ranges. The selective binding of m-AuNP to the mannose adhesin FimH of bacterial type 1 pili is demonstrated using transmission electron microscopy. The competition assay with free mannose suggests that m-AuNP binds FimH better than free mannose does. This work demonstrates that carbohydrate attached nanoparticles can be used as an efficient affinity label and a multi-ligand carrier in a biological system.Item Quantitative Analysis of Multivalent Interactions of Carbohydrate-Encapsulated Gold Nanoparticles with Concanavalin A(Royal Society of Chemistry, 2003-01-01) C.-C. Lin; Y.-C. Yeh; C.-Y. Yang; G.-F. Chen; Y.-C. Chen; Y.-C. Wu; Chia-Chun ChenMultivalent interactions between carbohydrate-encapsulated gold nanoparticles and Con A are found with high affinity and specificity.
