To optimize the strength of materials and structures used in biomedical applications, one must apply the principles of mechanics. This can become a challenging task in these multiphysics settings, says Lindsey Smith, a second year doctoral student in civil engineering at Johns Hopkins University. Smith is a member of the NanoBio IGERT with the Institute for NanoBioTechnology. Funded by the National Science Foundation, IGERT stands for Integrative Graduate Education and Research Traineeship.
Smith’s interest in structures and engineering blossomed after taking a high school introductory course on the topic. “I was always strong in math and science,“ she says. “I also was fascinated with architecture and large buildings.“ Smith graduated in 2003 from Columbia University with a major in Engineering Mechanics, which she describes as the study of the application of mechanics to civil engineering.

In his book “Life’s Matrix: A biography of water,“ author and Nature consulting editor Philip Ball declares that water is the “weirdest liquid.“ Dilip Asthagiri, assistant professor of chemical and biomolecular engineering, would agree. “There are very many puzzling features in all of aqueous chemistry and biology,“ says Asthagiri, an affiliated faculty member of the Institute for NanoBioTechnology. With a sub nanoscale diameter of about 3 Angstroms (0.3 nanometer), Asthagiri says, the water molecule is “more ‘nano’ than nano“ and an understanding of water is integral to this emerging science.

Assistant Professor Sharon Gerecht, an affiliated faculty member of the Institute for NanoBioTechnology in the Department of Chemical and Biomolecular Engineering at Johns Hopkins University, recently earned the Maryland Academy of Science’s 2008 Outstanding Young Engineering (OYE) award. The OYE award recognizes the extraordinary scientific contributions of Maryland residents under the age of 35.
Gerecht studies how changes in micro- and nano-scale environment can affect the growth and function of stem cells with focus on vascular development and regeneration. Gerecht is looking at ways to direct stem cell differentiation by engineering different chemical, mechanical and physical environments upon which the cells grow. This may have implications on how stem cells could be used in medical therapy.
“I believe that we are now in a unique position in which we know more about stem cells, their isolation, characterization, and have a basic understanding of their biology,“ says Gerecht. “This enables us to integrate advanced microengineering tools to better control their behavior both in the lab and in the body after transplantation“
As part of her award, Gerecht received a $2,500 cash prize and the Allan C. Davis Medal, named for the former Science Center board chairman whose gift helped fund construction of the Davis Planetarium. The Maryland Science Center, located at Baltimore’s Inner Harbor, is visited by more than 500,000 people each year.
Gerecht is the third INBT affiliated faculty member to be honored with an award from the Maryland Science Center. In 2007 David Gracias, also an assistant professor in the in the Department of Chemical and Biomolecular Engineering, received the OYE award. And in 2006, Anirban Maitra, associate professor of oncology and pathology at the Sol Goldman Pancreatic Cancer Research Center, was awarded the center’s Outstanding Young Scientist Award.

The Johns Hopkins Alumni Association annually recognizes university faculty who demonstrate superior skill in instruction with its Excellence in Teaching Awards. More than a dozen faculty members across JHU received the 2008 Alumni Association Excellence in Teaching Awards, one of whom was Hai-Quan Mao, an affiliated faculty member of the Institute for NanoBioTechnology and assistant professor in the Department of Materials Science and Engineering. The following was taken from a recent issue of the Johns Hopkins Gazette.

Hai-Quan Mao, Materials Science and Engineering
Hai-Quan Mao recalls his response last semester when one of his students botched the first part of a Thermodynamics of Materials midterm exam. “I was curious and a little upset because I had gone over the material with this student in a tutorial session,“ said Mao, an assistant professor in the Department of Materials Science and Engineering.
The student, among those who nominated Mao for the teaching honor, describes the event a bit differently. “I first realized that Dr. Mao was a unique teacher when, after the first day of the Thermodynamics midterm, he called me on my cell phone because he was ‘a little surprised that I did not answer all of the questions correctly,’ as we had conversed about the material several times prior,“ the student wrote on a nomination form. “He requested that I meet him in his office 10 minutes later, and we reviewed the first section of the exam.“
This story, the student said, had a happy ending: “Dr. Mao’s exceptionally sincere gesture to ensure that I understood all of my errors before the second part of the exam was successful,“ the student wrote. “I continued to perform well because of his help and ended up with an A in the challenging course.“
Mao was pleased to hear that his teaching is getting through to his students, particularly because English is not his first language. Mao was raised and educated in China and learned English in high school and college. “At the beginning, I was a little concerned about not communicating effectively with my students,“ Mao said. “That made me try harder in finding good ways to teach.“
His ties to Johns Hopkins go back to 1995, when he became a postdoctoral fellow in the Department of Biomedical Engineering. He later spent four years conducting research at a Johns Hopkins affiliate in Singapore. In 2003, he joined the Whiting School faculty, focusing his research on the design, synthesis and application of polymeric materials for drug and gene delivery and tissue engineering.
Despite the demands of this research, he continues to maintain a close rapport with his students, fielding questions even outside of his regular office hours.
“I find it so hard to say no to students when they knock on the door, particularly those who are sincere to learn,“ Mao said. “But if you do a good job in class, the number of students knocking on the door will eventually go down.“

Cancer can’t hide from light of nanobiophotonics
People reap the benefits of the harvesting of photons every day. Printers, DVD players, remote controls, lasers, sensors, and other similar devices all are based on photonics. But Paras Prasad, director of the Institute for Lasers, Photonics, and Biophotonics (ILPB) at the University at Buffalo, says there is much more to learn about the interaction of light with materials and its role in biomedical research. Prasad will discuss this topic at the Johns Hopkins 2008 NanoBio Symposium on May 1-2, hosted by the Institute of NanoBioTechnology.
“Photonics, in a broad sense, deals with the emission, transmission, amplification, detection, modulation, and switching of light,“ says Prasad. Through this manipulation of light, scientists and engineers are using photonics to discover new ways to deal with problems such as the diagnosis and treatment of disease or the generation and storage of energy.
For example, researchers at the University of Buffalo’s Institute for Lasers, Photonics, and Biophotonics have developed special kinds of plastic-based nanocomposites that can be fabricated into many structures and designs, including more efficient and larger-scale solar panels to gather the sun’s energy over the entire spectrum, including ultraviolet and infrared.
“Such hybrid nanocomposites can be used to harvest solar energy from larger structures in the form of tents, panels and coatings,“ Prasad says. Patents in this area are on file and a California-based company is now working to develop its commercial applications.
Also exciting, Prasad says, are the scientific advances in areas that marry biology, nanotechnology and photonics—nanobiophotonics. At this interface of disciplines, scientists and engineers are breaking new ground in the realms of health care and medicine, he says.
For instance, Prasad says, funding from the National Cancer Institute supports a partnership between the UB institute and researchers at Hopkins to develop better ways to diagnose and treat pancreatic cancer. Prasad’s group, together with teams lead by INBT affiliated faculty members Anirban Maitra of the Sol Goldman Pancreatic Cancer Research Center and Martin Pomper at the In Vivo Cellular and Molecular Imaging Center, are working on a project that “accelerates the advance of photonics and nanotechnology out of the lab and into the cancer clinic,“ he adds.
Pancreatic cancer is especially deadly, says Prasad, because survival rates are poor, even when a tumor is just barely observable at microscopic scales. Therefore early detection is critical to improve outcomes. The ILPB researchers have shown effective early detection of pancreatic cancer with quantum dots and metallic nanorods that have been conjugated with antibodies that specifically target pancreatic cells.
“We are developing diagnostic and treatment methods for pancreatic cancer that capitalize on our expertise in designing targeted hybrid ceramic-polymeric nanoparticles to better image pancreatic cancer in vivo and to deliver drugs more effectively to treat it,“ says Prasad. “It is very exciting to see that these photonic technologies developed at the University at Buffalo are being applied to a disease where the need for earlier detection and more effective treatment is so pressing.“
During his talk, Prasad also plans to highlight other nanobiophotonics research at ILPB including nanoparticles for photodynamic therapy of cancer and the use of nanoparticles in gene therapy particularly in the brain and liver. Prasad says these nanoparticles hold exciting prospects for developing new approaches for dealing with health care concerns with high societal impact, such as obesity, drug addiction and new infectious diseases.
