Summary:The immobilization of two different immunoglobulins by means of the layer by layer self assembly technique (LbL) was studied and evaluated for its use in the development of piezoelectric biosensors. Namely an antibody specific to transforming growth factor pi (anti-TGF-pl) and one specific to taxol were immobilized onto the surface of piezoelectric crystals by the LbL technique and their performance was characterized. The quartz crystal microbalance technique was employed to characterize both the step by step immobilization procedure and the response to the specific analytes. Atomic force microscopy was used to measure the roughness of the crystals before and after immunoglobulin immobilization. The results showed that the proposed immunosensors offer a promising alternative to classical analytical methods for a fast and easy determination of analytes of clinical interest.
DNA Functionalized Nanotube Array Technology The Emerging Technology lab leads a multidisciplinary research effort and collaborates with researchers from Brown, Boston College, and Drexel University in developing novel materials designed using DNA nanotechnology. Funded under an Air Force MURI program, the five year grant has delivered technology solutions capable of detecting biological analytes on a nanoelectronic sensor platform. Housing the design, fabrication, and material analysis and processing facilities, this lab is able to tailor highly ordered carbon nanotube arrays geometrical and chemical properties.
Highly ordered arrays of carbon nanotubes whose chemical properties can be used to conjugate nanoparticle labeled DNA. By controlling the location of DNA conjugation sites, gold nanoparticles can be self-assembled to the designated particular spot on a nanotube in an array, and subsequently zinc oxide nanowires can be grown at the site of the gold nanoparticle.
Liquid crystal gels, liquid crystal suspensions and liquid crystals as molding tools in self-assembly are the main areas of research in liquid crystalline materials.
Liquid crystal gels are low-molar-mass liquid crystals whose long-range orientation or textures are stabilized by a polymer network. Generally, the network is covalent since it is formed by polymerization of a reactive monomer dissolved in the liquid crystal host. The use of non-covalent, self-assembled networks is being explored for making liquid crystal gels, which when functionalized with photoresponsive groups, will create dynamic functional materials that have potential applications in display technologies.
Supramolecular chemistry is a recent approach to designing liquid crystalline materials, an approach that can combine small molecule and polymer properties as well as allow facile tailoring of the material properties. Thus, complementary polymers and mesogens are self-assembled through non-covalent interactions (ionic, hydrogen-bonding, coordination). The use of block copolymers leads to hierarchical structures combining the meso- and nanoscale. Stimuli-sensitive mesogens are chosen to generate intelligent materials for specific applications. These materials are being investigated in the bulk and as ultra-thin films. Under suitable conditions, rod-like colloidal particles can form liquid crystalline suspensions. When nanocrystals of cellulose are dispersed in water, they self-order to form chiral nematic phases with interesting physical and optical properties.
Silica exists in an infinite number of three-dimensional structures. At one extreme are a number of crystalline three-dimensional forms such as quartz. At the other are amorphous three-dimensional forms such as fumed silica. There are no known freestanding 1-or 2-dimensional forms of SiO2. Liquid crystal templates are being explored as potential method for the construction of low dimensional forms of SiO2.
Proteins made of chains of amino acids carry out most cell functions once folded into the proper structure.
The movie starts with the final crystal structure of the Villin protein. The colors represent different sequences in the protein....then it depicts how the villin folds into it's final structure over a period of sic microseconds.
Biological liquid crystals Lyotropic liquid-crystalline phases are abundant in living systems, the study of which is referred to as polymorphism. Accordingly, lyotropic liquid crystals attract particular attention in the field of biomimetic chemistry. In particular, biological membranes and cell membranes are a form of liquid crystal. Their constituent molecules (e.g., phospholipids) are perpendicular to the membrane surface, yet the membrane is capable of a range of elastic stress, leading to some aspects of elastic behavior to be exhibited. These lipids vary in shape (see page on lipid polymorphism). The constituent molecules can inter-mingle easily, but tend not to leave the membrane due to the high energy requirement of this process. Lipid molecules can flip from one side of the membrane to the other, this process being catalyzed by flippases and floppases (depending on the direction of movement). These liquid crystal membrane phases can also host important proteins such as receptors freely "floating" inside, or partly outside, the membrane, e.g. CCT. Many other biological structures exhibit LC behavior. For instance, the concentrated protein solution that is extruded by a spider to generate silk is, in fact, a liquid crystal phase. The precise ordering of molecules in silk is critical to its renowned strength. DNA and many polypeptides can also form LC phases and this too forms an important part of current academic research
The hex builds upon itself, about 8 times I think. There are some hexagon homes as well, that most likely have used Tesla for a long time, but the hexagon and the pentagon shapes\ are important to these folks, who have our BEST(their best) interests at heart.

Radio Frequency Identification (RFID) integrated circuits have been around for years, but these devices are now getting even smaller. The Mu-chip manufactured by Hitachi in Japan is claimed to be the world's smallest RFID chip. It uses the 2.45 GHz frequency (same as for Bluetooth and IEEE801.11b devices) and has a 128 bit ROM capable of identifying trillions of unique objects. At 0.4mm square it is small enough to be embedded in packaging and paper. Applications include electronic numbering of products and documents for manufacturing, distribution, consumption, tracking and recycling. It is expected to have a major impact on logistical efficiency, construction supply chains and the maintenance of building fabric and services installations. Production costs are reported to be as low as ¥20 (16 cents). Read more on this feature now ...

seems to be the same size as the hexagonal crystals being found coming from some of the people afflicted with Morgellon's. One tiny crystal was found airborne.
Hello everyone, am new here. I guess I am unsure if I am in the right place, so maybe if I give a quick update on where this began for me, someone can kindly let me know if I'm in the right place I seem to have alot of the symptoms......itching, small white things falling out of my hair and from my skin, 'hairs' seen floating in the air, brain fog, etc. This all seems to come and go in a cycle. I am at my whits end and am scared to speak with my dr about this. Yes....I've read about some of the horrible reactions you all have has and I feel so darned sorry about it
I lost alot of hair, and have scars that have just lost all color....are just white in the middle and they cover my whole face as well as body. They don't tan and it's pretty embarassing. My last bloodwork showed low b vit and potassium levels. I get tired very easy and at one point, when the white things were coming off of me like crazy, I got a small magnifying glass and looked and they appeared to almost have legs!!!! It always starts in my legs and then the symptoms increase each day and after about 10 days, they taper off and it's like it goes dormant. Does this sound familiar to anyone? I guess I am just lucky it's not 24/7 for me like others.... okay, trying to make it short, and if someone would be kind enought to reply..... God bless
I have pulled these out of my nose and one day, I had to detach if from the head of my penis. I kid you not. I am totally serious. It was incredibly painful and left two small holes, where I had ripped it off from. My bowels movements are occasionally littered with things that look like bugs. One time, I saw what appeared to be a small chunk of polymer with what looked like insect legs attached to it.
I am so tired of this BS. It killed my marriage and I struggle with it on a day-to-day basis. I cannot remember what it was like to have a normal, functioning, body.
Ok, now this is making me worry. To my knowledge I am not a Morgellon's sufferer, I have not experienced any of the symptoms, until this.
Almost my entire life, at least the past 15 years, I have seen these little sparkly flecks on my skin. In my younger days I just assumed they were in fact glitter flecks, that I must have come in contact with at some point.
But still to this day, on occasion, I will find them. Now, they are always on the outer layer of skin, but could very well be attached to skin cells, as I have never bothered to check, I usually just pluck it off and get rid of it.
what the heck is this stuff?

I'm sure most of you already know about this, but for newbies, this might add some clarity.
