Dynamic Droplets: Biosensors from Changes in Orientation and Morphology of Complex Liquids
Professor Timothy M. Swager
Massachusetts Institute of Technology
Protein kinases are critical players in intracellular signal transduction pathways and the etiology of many human diseases.
Over the last three decades, our understanding of this biological target class has grown such that there are now ca.
25 kinase inhibitors on the market, predominantly for the treatment of cancer. This presentation will describe the evolution of
kinase drug discovery and development using several clinical candidate case histories to highlight key past milestones and future challenges.
Molecular Imaging of Transition Metal Signaling in the Brain and Beyond
Professor Christopher J. Chang,
University of California, Berkeley
Metals are essential for all forms of life, and the traditional view of this bioinorganic chemistry is that mobile fluxes of alkali and alkaline earth metals like sodium,
potassium, and calcium are used as dynamic signals and transition metals like copper and iron must be buried and protected as static metabolic cofactors to prevent oxidative
stress. We have identified a new paradigm of transition metal signaling, using copper as a primary example to show how such elements can influence neural circuitry and regulate
fundamental behaviors such as eating and sleeping.
Shape-Shifting Drug Carriers for Targeting Cytotoxins and Immunotherapeutics to Cancer
Professor Nathan C. Gianneschi
University of California, San Diego
Nanoparticle targeting strategies have largely relied on the use of surface conjugated ligands designed to bind overexpressed cell-membrane receptors associated with a given cell-type.
We envisioned a targeting strategy that would lead to an active accumulation of nanoparticles by virtue of a supramolecular assembly event specific to tumor tissue, occurring in
response to a specific signal. For this purpose, we utilize enzymes as stimuli, rather than other recognition events, because they are uniquely capable of propagating a signal via
catalytic amplification. We will describe the preparation of highly functionalized polymer scaffolds utilizing ring opening metathesis polymerization, their development as in
vivo probes and their utility as a multimodal imaging platform and as drug carriers capable of targeting tissue. Furthermore, we will describe new methods and approaches for
characterizing this kind of dynamic material at the nanoscale, including by liquid cell transmission electron microscopy and combined isotopic and optical nanoscopy.

Metal-oxos in Chemistry and Biology
Professor Harry B. Gray
California Institute of Technology
The dianionic oxo ligand occupies a very special place in coordination chemistry, owing to its ability to stabilize high oxidation states of metals.
The ligand field theory of multiple bonding in metal-oxos was published in two papers in the first volume of Inorganic Chemistry. The theory, which
accounts for the ground state electronic structures and spectroscopic properties of these complexes, predicts that an “oxo wall” separates Fe-Ru-Os and Co-Rh-Ir
in the periodic table. I will review this early work, then discuss the roles metal-oxos play in two of the most important chemical reactions on planet Earth,
hydrocarbon oxygenation catalyzed by cytochrome P450, and solar-driven water oxidation catalyzed by photosystem-II.
Unlocking the Potential of Spherical Nucleic Acids in Biology and Medicine
Professor Chad A. Mirkin, Northwestern University
A fundamental tenet of nanotechnology is that bulk materials, when miniaturized, exhibit new and interesting chemical and physical properties.
These properties often positively impact the development of new technologies, especially in the areas of biology and medicine where frontier advances
require rapid changes in how living systems are probed and regulated. Spherical nucleic acids (SNAs), nanostructures typically made by chemically
templating short strands of DNA or RNA on the surface of a particle, display extraordinary architecture-dependent properties. Unlike conventional
nucleic acids, SNAs can rapidly enter cells without the need for transfection agents, and they can be utilized as novel intracellular probes and
efficacious agents for regulating gene expression and immune system response. Consequently, SNAs constitute an entire new class of therapeutics
that are being utilized to attack diseases and disorders, including autoimmune diseases and many forms of cancer, at their genetic roots.

Reminder - Please Pay Your New York
Local Section Voluntary Dues!
When your ACS membership renewal notice arrives this time, please be sure to renew but also don't forget to check the box for payment of New York Local Section Dues. While Local Section dues are a voluntary contribution - they are not required to maintain Section membership - they are however, critically important to the well being of the New York Section.
Your $11.00 Voluntary Dues directly fund events and services, including the prestigious annual Nichols Medal Symposium, undergraduate research symposia, topical groups, subgroups, and other excellent programs. With your financial commitment, these important programs can continue to grow and benefit all our members.
Thank you - the New York Section really appreciates your help!
Employers Seeking Talented Employees
The Employment and Professional Relations Committee maintains a roster of candidates who are ACS members seeking a position in the New York metropolitan area.
If you have job openings and would like qualified candidates to contact you, please send a brief job description and educational/experience background required to Hessy Taft.
Candidates from our roster who meet the requirements you describe will be asked to contact you.
Do you like to talk?
Then we need to hear from you!
The New York Section of the ACS is looking to increase and
update its Speakers Bureau database of interested local area
speakers who are available for Section-wide seminars and
symposia. If you have an area of research or interest that
would provide an interesting talk appropriate for our Section
members, and would like to be included in our Speakers Bureau,
then please contact the New
York Section Office (516-883-7510, Email) with the following information
that will be posted on the Section's website: your name,
affiliation, a title, and 5-6 words briefly summarizing your
area of specialty. We look forward to hearing from you about
topics that you wish to share with our other members!
