Initial Observations of Cell Mediated Drug Delivery to the Deep Lung
Director Nanomedicine Division,, Neuracon Biotech Inc
Using current methodologies, drug delivery to small airways, terminal bronchioles and alveoli (deep lung) is inefficient especially to the lower lungs. Urgent lung pathologies such as acute respiratory distress syndrome (ARDS) and post-lung transplantation complications are difficult to treat, in part, due to the methodological limitations in targeting the deep lung with high efficiency drug distribution to the site of pathology. To overcome drug delivery limitations inhibiting the optimization of deep lung therapy, isolated rat Sertoli cells pre-loaded with chitosan nanoparticles were use to obtain a high density distribution and concentration (92%) of the nanoparticles in the lungs of mice by way of the peripheral venous vasculature rather than the more commonly used pulmonary route. Additionally, Sertoli cells were pre-loaded with chitosan nanoparticles coupled with the anti-inflammatory compound curcumin and then injected intravenously into control or experimental mice with deep lung inflammation. By 24 hours post-injection, most of the curcumin load (~90%) delivered in the injected Sertoli cells was present and distributed throughout the lungs including the peri-alveloar sac area in the lower lungs. This was based on the high density, positive quantification of both nanoparticles and curcumin in the lungs. There was a marked positive therapeutic effect achieved 24 hours following curcumin treatment delivered by this Sertoli cell Nanoparticle Protocol (SNAP). Results identify a novel and efficient protocol for targeted delivery of drugs to the deep lung mediated by extra-testicular Sertoli cells. Utilization of SNAP delivery may optimize drug therapy for conditions such as ARDS, status asthmaticus, pulmonary hypertension, lung cancer and complications following lung transplantation where the use of high concentrations of anti-inflammatory drugs is desirable, but often limited by risks of systemic drug toxicity.

Overcoming Challenges in Advanced Semiconductor Imaging & Analysis
FEI Global Marketing Manager, NanoElectroincs, FEI Company
Time is Money in Nano-scale Semiconductor Manufacturing
Today's advanced semiconductors are truly nano-scale devices. For example, the latest generally-available PC processors feature transistor line-widths as small as 45 nm, and process development is underway at leading manufacturers for 32 nm, 22 nm, and even smaller geometries.
The adage, "Time is money" has an overwhelming relevance in the world of volume semiconductor production. Getting to market, enhancing yields and ramping to volume-- faster-- is business-critical, and overcoming the associated nano-scale manufacturing challenges requires sophisticated "forensics." In other words, advanced manufacturing process development and control applications require advanced imaging and analysis tools to characterize defects, analyze failures, and measure critical dimensions.

Funding Your Nano Startup
our country has well-defined areas where there's just more money and opportunities for new technology companies. States like Texas, Ohio, and even Oklahoma seem to be outpacing my home state of North Carolina when it comes to political leaders realizing the critical importance of seed stage companies in the lifecycle of job creation.
So what are your options if you don't live in Silicon Valley? What are the pros and cons of different strategies that help to minimize under-capitalization?

Teaching Nanoscale Science to K-12 Students
Judith Light Feather
President, The NanoTechnology Group Inc
Why do all students have to learn about nanoscale science?
Over the past 15 years I have attempted to answer this question in many ways, sometimes successfully and more often than not, have faced objections from all levels of educators. There are many stumbling blocks placed against inclusion of new areas of science in all grades. Many educators have become complacent teaching only the required standard-based curriculum for students in K-12. Many educators state that students are struggling to learn the basics in these primary subjects and are not competent in passing standardized testing in math, reading and grammar. Therefore, science topics are considered too difficult for them to comprehend at an early age. Getting past this first objection, along with the fact that teachers are overloaded with paperwork, mandatory state and federal testing and do not have time to introduce a new subject, has been an ongoing challenge. The second issue stated by teachers, "They do not know where to insert the resources developed as nanoscale science curriculum into their current teaching matrix. The universities that developed the curriculum did not match it to their current textbooks." Read the Whole Article

Our History Shapes the Future
Research Engineer, Novii Systems
American history teachers praise the educational value of Billy Joel's 1980s song ‘We Didn't Start the Fire'. His song is a homage to the 40 years of historical headlines since his birth in 1949.
Which of Joel's headlines will be considered the most important a millennium from now?
This column discusses five of the most important, and tries to make the case that three of them will become irrelevant, while one will be remembered for as long as the human race exists (one is uncertain). The five contenders are:

Green Chemistry Makes Many See Red
Green chemistry. What is this savior that will rescue our doomed planet from the evils of toxic chemicals? One basic premise is that they can be eliminated from many products by simply replacing them with non-toxic chemicals. In theory, this would make a nice situation where we would never have to be exposed to toxic substances and the new substances will be safe because we have designed substitutes which will not pose any threat to man nor beast. I remain skeptical but others are convinced this goal is achievable. While I don't claim to be a mystic with the ability to predict the future, I can say with a great deal of confidence that this is going to end badly. Read the Whole Article

WE ARE STRONG: Only Insofar As We Take Advantage of Our Innate Abilities and Build Smarter Tools
MSc, MPhil, PhD Researcher, University of Plymouth, Transhumanism
Humans are animals that build tools to enhance physiology. It is the use of tools that helped to increase the human brain into a larger, more complex system than that of early hominids. "Tools and bigger brains mark the beginning of a distinctly human line of evolution." (Kelly 2010, 22) According to Jared Diamond, early hominids lacked innovation: "In short, Neanderthal tools had no variation in either time or space to suggest that most human characteristics, innovation". (Diamond 2006, 44) What will we do with nanotechnology and AGI? Read the Whole Article

America Needs a New Strategy for Safe Drinking Water
CEO, Early Warning Inc
An estimated 19.5 million Americans, representing about 7% of the entire US population, got sick last year from drinking water containing pathogenic bacteria, viruses and parasites. Countless more consumed water with cancer-causing chemicals, radioactive substances, and nuclear materials. Pathogens and toxins are ending up in tap water from ineffective treatment of contaminated source water, infiltration of contaminants through broken water mains, an absence of government regulations that require drinking water to be adequately tested for multiple pathogens and hundreds of toxic materials, and a lax enforcement of regulations by government officials that allowed over 94% of Clean Water Act violators to avoid fines or significant punishments. Current trends suggest that the problems will intensify. An increase in America's population and related water-intensive industries such as food processing will require even more contaminant-free water, while at the same time pristine water sources are depleting.
Maintaining the status quo will likely lead to a greater number of illnesses from an aging population with an increasing number of sick, immuno-compromised, and malnourished who are less able to fight off pathogens and toxins. This will place a greater burden on the health care system. Rebuilding under-capacity water treatment plants and deteriorating water distribution infrastructure will take decades and approach a trillion dollars nationally in the next 20 years. A more cost-effective solution is to implement a new generation of nanotechnology-based inline sensors that rapidly detect a diverse suite of pathogens and toxins, along with updated regulations and meaningful enforcement. This will allow water operators to more quickly identify dangerous contaminants and take actions to prevent contaminated water from reaching consumers. With a network of sensors providing precise information about the sources of infiltration, water administrators would be able to prioritize major infrastructure projects by measuring the potential health benefit versus the cost of prospective investments.

Ethics of Human Enhancement: 25 Questions & Answers
Director, Ethics + Emerging Sciences Group
In our recent NSF-funded report, excerpted here, we examine many ethical and social issues surrounding human en-hancement technologies. No matter where one is aligned on this issue, it is clear that the human enhancement debate is a deeply passionate and personal one, striking at the heart of what it means to be human. Some see it as a way to fulfill or even transcend our potential; others see it as a darker path towards becoming Frankenstein's monster. To help untangle this debate, we have organized this report as the following list of questions and answers, starting with background issues and moving to specific concerns, including: freedom & autonomy, health & safety, fairness & equity, societal disruption, and human dignity.

Lithium-Ion Battery Research
Principal Technologist, QuantumSphere Inc
Commercially introduced in the early 1990s, lithium-ion batteries exhibited an annual market penetration rate of 25%, replacing less energy dense nickel metal hydride batteries. A typical commercial Li-ion battery has a specific energy of about 200Wh/kg, while some more advanced systems reached a specific energy exceeding 275 Wh/kg. Rechargeable lithium-ion batteries are the power source of choice in present-day electronic devices, such as laptop computers, cell phones, smart phones, cameras, and many more. Additionally, they are becoming a viable option for hybrid electric vehicles (HEVs) and plug-in electric hybrid vehicles (PHEVs).
