29 What can Suzie Hwang Pun’s accomplishments help?
(A)To control traffic and direct traffic flow
(B)To transport genes and drugs to the right place
(C)To grow new genes and viruses for cancer patients
(D)To improve human immune system to fight against cancer cells

Think of Suzie Hwang Pun as a traffic cop for genes基因. The 27-year-old chemical engineer uses polymers有機聚合物 to carry injected注射 genes基因 through the bloodstream體內迴圈的血液.

With a system of molecular分子 tags, she can direct a gene基因, for instance,one that blocks阻止 cancer progression進展, to just the right spot—like the nuclei of cells in a tumor.

It is a trick that couldsolve a problem in gene基因 therapy research: a new gene does no good if it does not reach the right place.

Whileviruses are the typical delivery vehicles in gene therapy, they are hard to manufacture製造 and can be intercepted攔截，截住 by the immune system. Pun’s polymer有機聚合物 materials avoid those problems and open the possibility of delivering drugs, as well as genes, with exquisite美麗的, 精美 precision精確性, 準確.

“This is the tip of the iceberg,” says Caltech chemical engineer MarkDavis. He was so excited by Pun’s accomplishments成就；成績 as a graduate大學畢業生 student in his lab that he founded Insert插入，添寫（文字、表格等） Therapeutics治療的；有療效 in Pasadena, Calif., primarily主要地 to commercialize商業化，使商品化 her work.

Pun jumped at the chance to be a seniorscientist高级研究员 and employee number one.

If all goes well, her technology could enter human trials試驗；試用 within a few years.
