Kudos to Alexandra LaLonde (3rd year BME student) and Maria Romero-Creel (2nd year BME student) on their acceptance for publication by the Journal of Chromatograpy A, a top journal in the field of Analytical Chemistry.

Alex and Maria’s project studied a microfluidic technique for concentrating micro-particles. particularly with insulator-based dielectrophoresis, a microscale technique that uses electric fields to move and enrich particles inside microchannels. This research can have applications for concentrating biological cells and biomolecules. The co-authors in this work are Dr. Aytug Gencoglu, Dr. Karuna Koppula and Dr. Blanca Lapizco-Encinas. The research was carried out at the Microscale Bioseparations Laboratory. The work was funded by the Seed Grants and Summer Internships Funds from the KGCOE, as well as the National Science Foundation. Read the entire unedited manuscript here.

Fall 2013

Dr. Thomas Gaborski attended and presented at the annual Biomedical Engineering Society (BMES) meeting in Seattle, WA. Dr. Gaborski presented a talk on “Low-Voltage Electroosmotic Flow and DNA Shearing Using Ultrathin Nanoporous Silicon Membranes” and co-chaired a session on Microphysiology Systems. The Gaborski Lab also presented two posters on “Large Area Ultrathin Transparent Silicon Membranes for High Content Cellular Imaging” and “Leukocyte Isolation and Sorting Using Microdiaphragm Pumping and Registered Microfiltration”. After enduring four days of torrential rains in Seattle, he was happy to return to sunny weather in Rochester. As a nanotech entrepreneur and biomedical engineer, Dr. Gaborski returns to Cornell University to give his annual lecture on “Improving Human Health with Nanotechnology: A Case Study on Hemodialysis” in October. The lecture is presented to graduate students enrolled in NanoBiotechnology and simulcast to the Cornell Medical School in NYC and two universities in Europe.

Dr. Blanca Lapizco-Encinas presented her paper, “Dynamic microparticle manipulation in dielectrophoresis-based microfluidic devices” at the 20th International Symposium on Electro- and Liquid Phase-separation Techniques, October 6-9, 2013, Canary Islands, Spain. This is the third time she has been invited to speak at this conference and she also chaired one of the technical sessions. Dr. Lapizco-Encinas will chair the conference when it returns to the United States in 2016.

 

Summer 2013

Department Director and Professor, Dan Phillips spent his summer keeping abreast of industry trends in biomedical engineering. He attended the Association for the Advancement of Medical Instrumentation conference in California where he saw the latest technologies showcased by 150 equipment manufacturers and service providers from around the world. Professor Phillips then traveled to Philadelphia for the Medical Design & Manufacturing Conference which featured topics such as FDA regulations, intelligent design, managing risk, and human factors. He finished his travles in Washington, D.C. at the MedTech Conference where he had opportunities to network wit over 1,000 companies.

Dr. Blanca Lapizco-Encinas receives first NSF research award!

cid:image006.jpg@01CE9CED.AF96A230 Dr. Blanca Lapizco-Encinas has been officially notified of the award and funding of her very first NSF grant.  The award was granted to support her proposal titled, "Rapid and Dynamic Cell Assessments in Dielectrophoresis-Based Microfluidic Devices." Dr. Lapizco-Encinas is the single Principle Investigator of this National Science Foundation Grant as part of their Fluid Dynamics Program. Information regarding the grant can be found via the NSF website .

BME Participates in Imagine RIT!

The Biomedical Engineering Society (BMES) Student Chapter at RIT displayed some of the projects that they had worked on during this past academic year. The exhibit included an interactive biomaterial experiment along with images of cell cultures and some of the research projects conducted by some of the BMES members.

Dr. Behnaz Ghoraani and her students at the Biomedical Signal and Image Analysis Lab (BSIA) at RIT displayed their recent advances in developing an instrument to alert patients with atrial fibrillation (AF) when they enter into an AF episode. AF affects 3 million Americans and is the most common cardiac arrhythmia, accounting for frequent hospitalizations and increased risks of stroke, heart failure and mortality.

BME Sophmore, Emily Holz, Receives Fellowship from NIST

Emily Holz received a fellowship from the National Institute of Standards and Technology (NIST) to work during this summer on the project, "Microsystems for Bio-Imaging and Metrology," with Dr. John Moreland at NIST's Boulder Colorado location. The project uses micro- and nano-systems (MEMS and NEMS) for new instrumentation in biomedical research. Emily feels very fortunate to have obtained her top research choice in this very competitive program.

Student, Lindsay Demblowski Headed to Rwanda

Lindsay Demblowski , second year BME student, is traveling to Rwanda this summer to provide assistance with medical equipment. This will be Lindsay's first co-op experience at the Summer Institute sponsored by Engineering World Health (EWH), a nonprofit organization dedicated to improving the quality of healthcare in hospitals in developing nations. EWH provides biomedical engineering students the opportunity to spend two months of their summer break in a developing nation working on medical equipment. Lindsay went through a rigorous application process that included multiple essays and interviews before being selected to participate in the program in Rwanda. For more information about Lindsay's co-op experience, please visit her blog at lademblowski.tumblr.com .

Students Head to Guatemala

First year engineering students, Melissa Mendoza, Andrew Wetjen, Emily Sanseverino, and Erik Freeman will be traveling to Guatemala to work with Dr. Randall Lou in the pediatric department of Nephrology, hypertension, dialysis, and transplants for Roosevelt Hospital located in Guatemala City. There students will work with doctors and the department's technician in the unit to give maintenance on current medical equipment. Students will also be brainstorming and trying to develop ways to make existing methods more efficient and cost effective. This is a completely voluntary effort that was started by Biomedical Engineering student, Melissa Mendoza, and Dr. Lou. All of the procedures carried out by Dr. Lou are completed using donations from the foundation he started named " Fundanier: Fundación para el Niño Enfermo Renal ."

Dielectrophoresis 2013

Gaborski NanoBio Device Lab presented at NanoDays

The Gaborski NanoBio Device Lab is proud to be a regular presenter at the Annual NanoDays weekend event at the Rochester Museum and Science Center. This year seven members of the Gaborski lab demonstrated everything from liquid crystal displays to hydrophobic sand and even invisibility. NanoDays is a nationwide festival of educational programs about nanoscale science and engineering and its potential impact on the future. NanoDays events are organized by participants in the Nanoscale Informal Science Education Network.

Junior Kayla Wheeler Honored for Giving Back

Biomedical Engineering junior Kayla Wheeler was named to the Allstate Women's Basketball Coaches Association Good Works Team as part of the women's Final Four festivities Sunday night.

Wheeler was one of only five student-athletes chosen among from Division II, III and NAIA institutions.

Microfluidics Workshop

Dr. Blanca Lapizco-Encinas and Dr. Aytug Gencoglu from the Microscale Bioseparations Lab and BME program presented a microfluidics workshop to the middle school students from Rochester school 43. This outreach workshop is part of the BEYOND NINE POINT EIGHT program organized by Professor Satish Kandlikar. Participating students made small channels from Jell-O and observed liquid mixing through diffusion. They also learned the concept of microfluidics and compared the differences between macro and micro scales.
