The Hopkins Extreme Materials Institute hosts the talk, “Bioinspired Micropatterned Surfaces with Switchable Functionality” with speaker Eduard Arzt, Scientific Director of the Leibniz Institute for New Materials and Department of Materials Science, Saarland University (Germany) on Wednesday, June 18 at 11 a.m. in B17 Hackerman Hall.
Abstract: New surfaces and coatings can drastically improve the properties and applicability of materials. At INM, we develop and investigate new micro- and nanopatterned surfaces for diverse functionalities: low friction, adhesion, corrosion protection, anti-reflection, electric storage and combinations of these. Such surfaces either exhibit new chemistries or new topographies, sometimes on different hierarchical levels. This talk will first summarize some of our developments by bridging the scientific principles with existing or emerging applications. It will then focus on micropatterning of surfaces for novel adhesive functionalities: the exploitation of judiciously designed surface protrusions, “fibrils” and other features at the micron scale – as insects, spiders and geckos – to create fundamentally new degrees of freedom for mechanical and other surface functions. Our extensive research in this area has recently led to the following results: i)design of active surfaces that exploit a transition from an adhesive to non-adhesive state, ii) first implementation in active pick-and-place systems, and iii) our recent developments in producing functional surfaces for interaction with soft materials, such as human skin. Our current emphasis is on controlling adhesion and friction, which is of great potential interest in microfabrication, construction industry, and sports equipment. Such developments require modeling and simulation activities which help understand the micromechanics of patterned adhesion and identify optimum parameters in a vast parameter space.
This talk is free and open to the Hopkins community. Johns Hopkins Institute for NanoBiotechnology supports this event.
Johns Hopkins Institute for NanoBioTechnolgy’s first professional development seminar of the summer will be held June 4 at 10:30 a.m. in Schaffer 3 (downstairs). This week we will have a graduate panel give three different perspectives of the graduate school process. The panel consists of current PhD students and recent graduates of INBT laboratories, all from the Department of Chemical and Biomolecular Engineering.
Quinton Smith was a previous REU (twice!) and works in Sharon Gerecht lab. He will give his perspective of how you can transitions from being an REU to a graduate student.
Luisa Russell can give a general perspective on graduate school, the admissions process, choosing a lab, etc. She is a second-year PhD candidate in the materials science department working on hybrid multifunctional nanoparticles in Peter Searson’s research group.
Allison Chambliss recently defended her PhD and can give the full perspective of being a graduate student, research, defending and looking for a job. She was part of the Denis Wirtz laboratory.
This event is free and open to the Hopkins community.
INBT will host a special seminar, “From bacterial intelligence to a cyber-war on cancer,” on April 17 at 2 p.m. in Room 160 of the Mattin Center. The guest speaker is Eshel Ben-Jacob, PhD, professor and Maguy-Glass Chair in Physics of Complex Systems from Tel Aviv University. This event is free and open to the university community.
ABSTRACT: Cancer continues to elude us. Metastasis, relapse and drug resistance are all still poorly understood and clinically insuperable. Evidently, the prevailing paradigms need to be re-examined and out-of-the-box ideas ought to be explored. Drawing upon recent discoveries demonstrating the parallels between collective behaviors of bacteria and cancer, Dr. Ben-Jacob shall present a new picture of cancer as a society of smart communicating cells motivated by the realization of bacterial social intelligence. There is growing evidence that cancer cells, much like bacteria, rely on advanced communication, social networking and cooperation to grow, spread within the body, colonize new organs, relapse and develop drug resistance. Dr. Ben-Jacob shall address the role of communication, cooperation and decision-making in bacterial collective navigation, swarming logistics and colony development. This will lead to a new picture of cancer as a networked society of smart cells and to new understanding of the interplay between cancer and the immune system. Dr. Ben-Jacob shall reason that the new understanding calls for “a cyber-war” on cancer – the developments of drugs to target cancer communication and control.
THIS SEMINAR HAS BEEN CANCELLED DUE TO THE THREAT OF A WINTER STORM AND WILL BE RESCHEDULED.

The National Cancer Institute (NCI) Center for Strategic Scientific Initiatives (CSSI) is a component of the NCI’s Office of the Director focused on emerging advanced technologies that have the potential of uniquely impacting the full spectrum of cancer basic and clinical research. The Center is tasked with planning, developing, executing, and implementing rapid strategic scientific and technology initiatives that keep the Institute ahead of the scientific curve with respect to potential new exciting areas and discoveries. This may involve direct development and application of advanced technologies, synergy of large scale and individual initiated research, and/or using available federal mechanisms to forge novel partnerships that emphasize innovation, trans-disciplinary teams and convergence of scientific disciplines. With an emphasis on complementing the scientific efforts of other NCI divisions, CSSI’s efforts seek to enable the translation of discoveries into new interventions, both domestically and in the international arena, to detect, prevent and treat cancer more effectively. This presentation will highlight various programs and their associated accomplishments within CSSI’s broad scientific portfolio of programs (Clinical Proteomic Tumor Analysis Consortium, Alliance for Nanotechnology in Cancer, Physical Sciences-Oncology Centers, Innovative Molecular Analysis Technologies, and Provocative Questions) and describe future directions and opportunities.
