Lycurgus Cup Named after King Lycurgus of Thrace whos depicted on the cup Lycurgus Cup

1600 years old Made of gold and dichroic glass Acquired by the British Museum in the 1950s It took scientists decades to understand why the colour of the glass changed (1990 according to http://www.ancient-origins.net/news-historyarchaeology/1600-year-old-goblet-shows-rom ans-used-nanotechnology-00793#!bjfuCU Sept. 2, 2013 article Lycurgus Cup

In order to produce the dichroic effect on the chalice, Roman artisans are believed to have ground down particles of gold and silver to 50 nanometres in diameter, which is less than one-thousandth the size of a grain of table salt, and then laid these nanoparticles within the glass before it set. When metals are the size of nanoparticles, they are able to display iridescent colours, which is what causes the colour to change in the Lycurgus Cup. Lycurgus Cup

While there continue to be scientific debates about whether the Romans discovered nanotechnology by accident or whether they deliberately calculated the size and quantity of nanoparticles required to make dichroic glass, no one has been able to replicate the effect, until now.

Lycurgus effect 2013 They [researchers University of Illinois at UrbanaChampaign] conducted a study last year in which they created a plastic plate filled with gold or silver nanoparticles, essentially creating an array that was equivalent to the Lycurgus Cup. When they applied different solutions to the plate, such as water, oil, sugar and salt, the colours changed.

Robotics UKs National Physical Laboratory reaches out to BioTouch MIT and UCL haptic-enabled sensing and micromanipulation of biological self-assembly BioTouch The project will probe sensing and application of force and related vectors specific to biological self-assembly as a means of synthetic biology and nanoscale construction Ultimately this is for a robot that can apply

sensitive touch and requires more than one technology to enable it Robotics Bio-inspired robotic sock from Singapore for deep vein thrombosis or blood clots Equipped with soft actuators that mimic the tentacle movements of corals, the robotic sock emulates natural lower leg muscle contractions in the wearers leg, thereby promoting blood circulation throughout the wearers body.

Robotics For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (boneanchored) implant system gives patients new opportunities in their daily life and professional activities. In January 2013 a Swedish arm amputee was the first person in the world to receive a prosthesis with a direct connection to bone, nerves and muscles.

Robotics Robert Downey Jr. (Iron Man 3 had a nano theme) RDJ delivered a gift to 7-year-old Alex: a very special custommade gift for the dapper looking boy with a partially developed right arm. The prosthetic, created by non-profit company Limbitless Solutions, demonstrates the power and cost-effectiveness of 3D printing technology but more than that, its pretty darn cool looking. At only $350 (minus the cost of the Arc Reactor!) Normally a prosthetic of this kind would cost upwards of $40,000, but with 3D printing dreams are being made into reality at an affordable price.

Andemariam Teklesenbet Beyene Synthetic trachea transplant 2011 http://www.frogheart.ca/?p=4078 Student in Iceland, flown to Sweden for transplant by surgeon, Paolo Macchiarini, who has a double appt. Karolinska Institute in Sweden and University College in London, UK Regenerative medicine Alexander Seifalian (UCL Division of Surgery &

Interventional Science; professor of nanotechnology and regenerative medicine at University College London, UK), created a glass mold of the patients trachea from X-ray computed tomography (CT) scans of the patient. Regenerative medicine Seifalian & associates manufactured a full size y-shaped trachea scaffold Scaffold was built using a novel porous

nanocomposite polymer The composite has millions of little holes (pores), providing a place for the patients stem cells to grow roots Regenerative medicine The team cut strips of the novel nanocomposite polymer and wrapped them around the glass mold creating to create cartilage rings that confer structural strength to the trachea

Then off to Karolinska where stem cells are harvested and grown in a bioreactor Regenerative medicine During a 12-hour operation Professor Macchiarini removed all of the tumour and the diseased windpipe and replaced it with the tailor-made replica [now covered with tissue grown from the patient's bone marrow tricked into growing like cells found in a trachea The nanocomposite was designed to disintegrate

over time leaving the organic trachea in place. Organ-on-a-chip Definition: An organ-on-a-chip ... is a multichannel 3-D microfluidic cell culture chip that simulates the activities, mechanics and physiological response of entire organs and organ systems. ... One day, they will perhaps abolish the need for animals in drug development and toxin testing. (https://en.wikipedia.org/wiki/Organ-on-achip)

Organ-on-a-chip While cells are conventionally cultured in a culture flask or dish in an incubator, in the Organ-on-Chip concept they are cultured inside a so-called chip. This chip would not be a microprocessor or integrated circuit such as on bank card However, it can actually have been made using the same type of microfabrication process in a clean room.

Organ-on-a-chip The chip provides the basic housing for the cells which will form the tissue or organ model. As such it replaces the conventional culture dish. Chip is roughly the size of a microscope slide contains one or more closed chambers these chambers contain cells which multiply or differentiate depending on the research Chip is made of a transparent material for viewing through a microscope

Organ-on-a-chip The chambers on a chip (microchambers) can have surfaces with different characteristics e.g., very thin, flexible and stretchable, similar to a membrane (thickness in the range of microns for example), they are non-toxic for the cells, allow passage of, for example, oxygen or nutrients surface can be patterned, or for example designed to contain pores of a defined diameter all from nanometer to micrometer sized

Human-on-a-chip International competition to get multiple organs on a chip In particular, US & Germany in competition Dan Tagle (associate director of the NIHs National Center for Advancing Translational Sciences): stated they would have human-on-a-chip by 2017 Uwe Marx (TissUse): currently sells two organs on a chip; says he has four organs on a chip

This technique would bypass animal testing Biomimicry aka, bioinspired engineering or biomimetics Examples: Human-on-a chip Inquiry into chameleon skin and structural colour (Mar. 2015: http://www.frogheart.ca/?p=16247) Scientists found a two-step process where changes take place via the active tuning of a lattice of nanocrystals present in a superficial layer of dermal cells called iridophores.

The researchers also reveal the existence of a deeper population of iridophores with larger and less ordered crystals that reflect the infrared light. it allows the chameleons to rapidly shift between efficient camouflage and spectacular display, while providing passive thermal protection [http://www.frogheart.ca/?p=16247] Biomimicry and structural colour Hard to believe those berries were collected more than four decades ago, according to Cristina Luiggi in her Feb. 1, 2013 article, Color from Structure, for The Scientist magazine. Her focus is on

biological nanostructures and it is a fascinating article which I urge you to read. Biomimicry and sharks researchers try to make materials that mimic a process or ability observed in nature. They used sharkskin as an example for making a smarter material. Scientists have observed that nanoscale structures on a sharks skin have antibacterial properties. This is especially important when we have a growing problem with bacteria that are antibiotic resistant. David Pogues (the program host)

interviewed scientists at Sharklet and highlighted their work producing a plastic with nanostructures similar to those found on sharkskin for use in hospitals, restaurants, etc. Biomimicry
