    • A press-down type composite putty knife which comprises a handle and a blade with a rear end of the blade inserted into a blade receiving slot at a front end of the handle; the rear end of the blade has a blade tang which is provided with a fixing notch; a latch is disposed at the front end of the handle inside its casing; latch springs are disposed under the latch for returning the latch to its original position; a pressing part is formed by an upper end of the latch which extends outwardly from an upper surface of the handle; a longitudinal slot in communication with the blade receiving slot is disposed at a lower portion of the latch; a fixing block corresponding to the fixing notch of the blade tang is disposed on a bottom surface of the longitudinal slot. The engagement between the latch and the fixing notch allows the handle and the blade of the present invention to be removably assembled, and therefore fulfill the object of replacing blades of different specifications on the same handle. Cost of use will be lower accordingly and carrying the knives becomes more convenient.
    • 一种压下型复合油灰刀,其包括手柄和刀片,刀片的后端插入到手柄前端的刀片容纳槽中; 叶片的后端具有设置有固定凹口的叶片柄, 在其壳体内的把手的前端设置有闩锁; 闩锁弹簧设置在闩锁下方,以将闩锁返回到其初始位置; 按压部分由从手柄的上表面向外延伸的闩锁的上端形成; 与刀片接收槽连通的纵向槽设置在闩锁的下部; 对应于叶片柄的固定凹口的固定块设置在纵向槽的底表面上。 闩锁和固定凹口之间的接合允许本发明的手柄和刀片可拆卸地组装,因此实现在相同手柄上更换不同规格的刀片的目的。 使用成本相应降低,携带刀变得更加方便。

    • Negatively charged luminescent CdSe—ZnS quantum dots (QDs) were successfully incorporated into novel luminescent glyconanospheres averaging around 190 nm in diameter through electrostatic interactions with carboxymethyldextran (CM-dextran) and polylysine. The glyconanospheres preferably contain as well carboxyl-modified iron oxide nanocrystals. In addition to electrostatic attraction between the negatively charged dextran, the negatively charged CdSe—ZnS QDs (and negatively charged iron oxide nanocrystals, if present), and the positively charged polylysine, covalent amide bonds were introduced to cross link the QDs (and negatively charged iron oxide nanocrystals, if present) with the polysaccharide matrix to further stabilize the glyconanospheres. The dextran residues on the surface of the nanospheres show high affinity toward the glucose binding protein-Concanavalin A (Con A). As a result, these luminescent CdSe—ZnS QD incorporated glyconanospheres are a useful tool for studying carbohydrate-protein interactions that are critical steps in bacterial and viral infection.
    • 通过与羧甲基葡聚糖(CM-葡聚糖)和聚赖氨酸的静电相互作用,将带负电的发光CdSe-ZnS量子点(QDs)成功地并入平均约190nm直径的新型发光糖球中。 优选地,葡萄球藻中含有羧基改性的氧化铁纳米晶体。 除了带负电荷的葡聚糖之间的静电吸引,带负电荷的CdSe-ZnS量子点(和带负电荷的氧化铁纳米晶体,如果存在)和带正电荷的聚赖氨酸,引入共价酰胺键以交联QD(和带负电荷的 氧化铁纳米晶体(如果存在)与多糖基质一起进一步稳定糖藻球。 纳米球表面的葡聚糖残基对葡萄糖结合蛋白 - 伴刀豆球蛋白A(Con A)表现出高亲和力。 结果,这些发光的CdSe-ZnS QD掺入的糖藻球是研究碳水化合物 - 蛋​​白质相互作用的有用工具,这是细菌和病毒感染的关键步骤。
