科技英语教案大学英语读写四教案③宏观量子隧道效应宏观量子隧道效应是指纳米粒子的一些宏观量（如磁化强度）具有贯穿势垒的能力。

这一效应限定了磁盘、磁带等存储介质的存储时间极限，因为它不但是未来微电子器件的发展基础，也是其进一步微型化的极限。

例如，在制造半导体集成电路时，当电路的尺寸接近电子波长时，电子将通过隧道效应而穿透绝缘层，使器件无法正常工作。

因此，宏观量子隧道效应已成为微电子学、光电子学中的重要理论。

“Targeting Drug Delivery System”靶向给药系统或称靶向制剂，诞生于20世纪70年代，是指这种制剂能将药品运送到靶器药物通过局部或全身血液循环而浓集定位于靶组织、靶器官、靶细胞的给药系统官或靶细胞，而正常部位几乎不受药物的影响。

①Targeted drug delivery, sometimes called smart drug delivery,[1] is a method of delivering medication to a patient in a manner that increases the concentration of the medication in some parts of the body relative to others.②The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue.③The conventional drug delivery system is the absorption of the drug across a biological membrane, whereas the targeted release system is when the drug is released in a dosage form.④The advantages to the targeted release system is the reduction in the frequency of the dosages taken by the patient, having a more uniform effect of the drug, reduction of drug side effects, and reduced fluctuation in circulating drug levels. The disadvantage of the system is high cost which makes productivity more difficult and the reduced ability to adjust the dosages.⑤There are two kinds of targeted drug delivery, active targeted drug delivery, such as some antibody medications; and passive targeted drug delivery, such as the enhanced permeability and retention effect (EPR-effect).⑥Delivery vehiclesThere are different types of drug delivery vehicles, such as, polymeric micelles, liposomes, lipoprotein-based drug carriers, nano-particle drug carriers, dendrimers etc. An ideal drug delivery vehicle must be non-toxic, biocompatible, non-immunogenic, biodegradable and avoid recognition by the host's defense mechanisms.Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size range with various targeting ligands attached to their surface allowing for their surface-attachment and accumulation in pathological areas for treatment of disease. The most common vehicle currently used for targeted drug delivery is the liposome. Liposomes are non-toxic, non-hemolytic and non-immunogenic even upon repeated injections; they are biocompatible and biodegradable4.Text comprehension ( 35 minutes)Ask the students to read the text and discuss the following questions.1)What did NCI announce?Tips: (Para.1) nanotech solutions to cancer2)What is nanotech?3)Why does it hold promise for cancer detection and therapy?Tips: (Para.2) Size and function.Targeted Drug Delivery System4)What are the delivery vehicles for cancer detection?Tips: two kinds of nanoparticlesnanocrystals of iron oxide (Para.3-5)quantum dot-probes (Para.6-8)5)Please find out the related researchers and the discoveries of their research.Tips:Nanocrystals of iron oxide:Researcher: Jinwoo Cheon, a chemist at Yonsei Universary in Seoul, South Koreareported in the Sept. 7 Journal of the American Chemical SocietyHis report: It can make MRI pick out smaller tumors (Para 3-4); An experiment.

Symmetric division gives rise to two identical daughter cells both endowed with stem cell properties. Asymmetric division, on the other hand, produces only one stem cell and a progenitor cell with limited self-renewal potential. Progenitors can go through several rounds of cell division before terminally differentiating into a mature cell.“The value of hES cells in recovering spinal cord injuries”科技英语教案科技英语教案科技英语教案科技英语教案科技英语教案。
