Taking second place was Anirudha Sing, Jianan Zhan and Jennifer Elisseeff with the poster Directed Stem Cell Differentiation Using PEG-alpha CD-derived biomaterials. First author Singh claimed the $100 Best Buy card.

A $50 Best Buy card was presented to Spyros Stamatelos who was first author with Eugene Kim, Arvind Pathak and Aleksander Popel on the poster Characterization of the Heterogeneity of Tumor Vasculature using Hemodynamic Modeling and High Resolution Imaging Implications for Drug Delivery.

Honorable mention was given to Jack Andraka, a high school research intern in the lab of Anirban Maitra who worked with Venugopal Chenna. Andraka’s poster, A Novel Paper Sensor for the Detection of Pancreatic Cancer, helped him win a free book from Springer.

The event was held  at the Johns Hopkins medical campus in the Owens Auditorium on May 4 with six faculty expert speakers and approximately 400 people in attendance.

Students talk cancer nanotech at Homewood March 21

Students affiliated with the Center of Cancer Nanotechnology Excellence (CCNE) and the Physical Sciences-Oncology Center (PS-OC) at Johns Hopkins University have organized a spring mini-symposium for March 21, 10 a.m. in the Hackerman Hall Auditorium at the Johns Hopkins University Homewood campus.

The student-run mini-symposiums aim to bring together researchers from across the campus affiliated with the PS-OC and CCNE. Graduate students training in these centers, both administered by Johns Hopkins Institute for NanoBioTechnology, work in various disciplines from physics to engineering to the basic biological sciences but with an emphasis on understanding cancer metastasis and developing methods for cancer diagnosis or therapy.

The invited speaker for the symposium is postdoctoral researcher Megan Ho of Duke University. Ho earned her PhD in mechanical engineering in the Wang lab in 2008. She is currently focused on developing microfluidic devices to investigate and control the fundamental reactions that form nanocomplexes for gene delivery. (10 a.m.)

Student apeakers, who will talk for 15 minutes, include:

  • Jane Chisholm (Justin Hanes lab/Ophthalmology): Cisplatin nanocomplexes for the local treatment of small cell lung cancer (10:20 a.m.)
  • Yunke Song (Jeff Wang Lab/Mechanical Engineering): Single Quantum Dot-Based Multiplexed Point Mutation Detection by Gap Ligase Chain Reaction (10:35 a.m.)

Session A: 1-3 pm

1. Electrospinning of polymeric nanofibers for tissue engineering application: Nanofibrous materials are increasingly used in tissue engineering and regenerative medicine applications and for local delivery of therapeutic agents. Electrospinning is the most widely used method for producing nanofiber matrices because of its high versatility and capacity to generate nanofibers from a variety of polymer solutions or melts. It can generate fibers with diameters ranging from tens of nanometers to a few microns. This workshop will review the basic principle of electrospinning, investigate the effect of several key parameters on fiber generation, demonstrate the method to generate nanofiber mesh and nanofiber conduits, and discuss the potential applications for tissue engineering and repair.

Instructors: Russell Martin and Hai-Quan Mao (Mao Lab)

2. Particle tracking microrheology: This hands-on course will teach participants the fundamentals and applications of high-throughput approaches to cytometry, including cell morphometry and microrheology. These approaches are being used for rapid phenotyping of cancer cells.

Instructors: Wei-Chiang Chen, Pei-Hsun Wu, and Denis Wirtz (Wirtz Lab)

Session B: 3:30-5:30 pm

3. Synthesis of quantum dots for bioengineering: This workshop will provide a hands-on approach to the synthesis of CdSe QD cores and how to purify these cores from excess surfactant. A brief discussion how to successfully electrically passivate the cores will follow. Participants will be able to water solubilize core/shell QDs using pegylated lipids. Several methods for characterizing the QDs through the synthesis and water solubilization will be performed.

Instructors: Charli Dvoracek, Justin Galloway, and Jeaho Park (Searson Lab)

4. Microfluidics for studying cell adhesion: This workshop will focus on fabrication of an “artificial blood vessel” via photolithography to generate a micron-sized (cross-section) channel. The micro-channel will be connected to a syringe pump to initiate fluid flow simulating the blood flow inside a blood vessel. This tool can be used to study how cancer cells interact with “blood vessel” surface when coated with adhesion proteins.

Instructors: Tommy Tong and Eric Balzer (K. Konstantopoulos Lab)

About 30 people attended a mini-symposium on cancer nanotechnology hosted by Johns Hopkins Institute for NanoBioTechnology March 23. The event showcased current research from nine students affiliated with its Physical Sciences-Oncology Center (PS-OC) and Center of Cancer Nanotechnology Excellence (CCNE). Talks began at 9 a.m. in Hackerman Hall Auditorium.

“We become so focused on our own research that we don’t know what other students are working on,” said Stephanie Fraley, a predoctoral candidate chemical and biomolecular engineering in the laboratory of Denis Wirtz. “The beauty of an event like this is that we get to see work from across the campuses and across disciplines, all in one morning.”

Researchers, who each spoke for 15 minutes and fielded questions from the audience,  included the following:

  • 9:00 – 9:15 – Jeaho Park (Peter Searson Lab, CCNE): Quantum dots for targeting cancer biomarkers
  • 9:15 – 9:30 – Stephanie Fraley (Denis Wirtz Lab, PSOC): Role of Dimensionality in Focal Adhesion Protein Localization and Function
  • 9:15 – 9:30 – Kelvin Liu, PhD, (Jeff Wang Lab, CCNE): Decoding Circulating Nucleic Acids in Serum Using Microfluidic Single Molecule Spectroscopy
  • 9:45 – 10:00 – Laura Dickinson (Sharon Gerecht Lab, PSOC): Functional surfaces to investigate cancer cell interactions with hyaluronic acid
  • 10:00 – 10:15 – Craig Schneider (Justin Hanes Lab, CCNE): Mucus-penetrating particles for the treatment of lung cancer
  • Break
  • 11:00 – 11:15 – Eric Balzer, PhD, (K. Konstantopoulos Lab, PSOC): Migrating tumor cells dynamically adapt to changes in environmental geometry
  • 11:15 – 11:30 – Venugopal Chenna (Anirban Maitra Lab, CCNE): Systemic Delivery of Polymeric Nanoparticle Encapsulated Small Molecule Inhibitors of Hedgehog Signaling Pathway for the Cancer therapy
  • 11:30 – 11:45 – Sam Walcott, PhD, (Sean Sun Lab, PSOC): Surface stiffness influences focal adhesion nucleation and decay initiation, but not growth or decay
  • 11:45 – 12:00 – Yi Zhang (Jeff Wang Lab, CCNE): A quantum dot enabled ultrahigh resolution analysis of gene copy number variation

John Fini, director of intellectual property for the Homewood campus schools, also gave a presentation on intellectual property and work of Johns Hopkins Technology Transfer.  Plans are in the works for the cancer nanotechnology min-symposiums to occur each spring and fall.

Johns Hopkins Physical Sciences-Oncology Center (PS-OC), also known as the Engineering in Oncology Center, is funded by a grant from the National Cancer Institute and aims to unravel the physical underpinnings involved in the growth and spread of cancer. Johns Hopkins Center of Cancer Nanotechnology Excellence, also funded by a grant from the NCI, aims to use a multidisciplinary approach to develop nanotechnology-based tools and strategies for comprehensive cancer diagnosis and therapy and to translate those tools to the marketplace.
