The blood reveals a tremendous amount of information about the body. It’s no wonder why that’s usually the first place your doctor will turn to determine just how well your body is functioning.
However, the process of completing a blood test involves some skill and a considerable quantity of materials. What if it were possible to gather specific information from the body by unitizing sensors implanted directly within the body? That may be possible through carbon nanotubes.

Instant Insight Inside the Body
Recently presented at a meeting of the American Chemical Society in Boston, new research has shown how tiny diagnostic sensors made from carbon nanotubes and polymers could be used to detect a variety of changing conditions within the body.
The resulting information could then be rapidly delivered to doctors and result in more precise and prompt care of a patient.
The new research has determined that the nanotube sensors can be safely implanted under the skin or within the bloodstream to measure changes in a range of biological compounds, such as presence of inflammation, fluctuation in insulin, nitric oxide, and certain clotting factors.
The Challenges Of Diagnostic Implants
The polymers used to create the carbon nanotube sensors are able to sense specific conditions down to the molecule. In tests in laboratory mice, the sensors successfully emitted a continuous signal and were not broken down by the body, nor did they cause any side effects for 400 days.
This duration is significant, as the development of long term diagnostic implants have come with a range of challenges.
The body will often treat the foreign object as biological material to be recycled, broken down, or covered in scar tissue. In this most recent research, nitric oxide sensors showed considerable promise for passing through the body without issue.
After being injected into the bloodstream, they even successfully traveled through the small capillaries of lung tissue.

The Future Of Lifesaving Medical Testing
As this technology shows immense promise for highly efficient diagnosis of medical issues, does this mean that medical product manufactures should worry that conventional blood-testing materials will soon be obsolete?
That’s not quite the case. Carbon nanotubes still come with a much higher price tag than blood work essentials and the processes needed to complete all necessary lab-work.
While the carbon nanotube sensors show substantial promise, they still have to be tested for comparably successful performance in humans. Even then, the conventional blood test will likely remain a standard while carbon nanotube sensors will probably be reserved for more critical medical testing needs.

Medical Device Manufacturers Use Robots For Speed, Safety, And Cleanliness
Robotic equipment in medical device production lines allows companies to maintain high standards of cleanliness, worker safety, product consistency, and speed. From heart valves to artificial joints to surgical equipment, robots increasingly play an integral role in medical device manufacturing.
Robots Limit Biological Contamination
Manufacturing facilities have long contended with the contamination issues introduced by human workers. Robots allow for the removal of the human element from many production areas. In addition to maintaining sanitary environments, robotic installations have aided manufacturers during the coronavirus pandemic. The CEO of MICRO said that greater integration of robots in workflows helped to limit human-to-human contact among workers.
Precise And Consistent Results
On top of sanitation, medical devices require high degrees of precision. Robots are capable of extreme dexterity that a human worker cannot replicate with consistency. Medical device companies draw upon the robotic developments pioneered by the electronic and automotive industry that turned to robots to build miniature components. New production processes for building artificial heart valves have incorporated small robots that perform highly detailed work on small parts with repeatable accuracy.
Elimination Of Workplace Sharps Hazards
A multitude of medical devices and tools involve very sharp edges. Fabrication of these instruments historically exposed workers to the risk of serious cuts. The installation of robots to grind, deburr, and package medical sharps reduces risks of worker injury. Workers focus instead on monitoring operations while robots produce precision goods at speeds beyond what human workers could achieve.
Robots Aid Industry Expansion
Tecomet Inc. in Boulder, Colorado, is in the middle of expanding operations. In addition to hiring more workers, the company will add another 25 machines, including robotic systems, to its new facility. Longer-term, the company anticipates that it will manufacture robots for clients operating cleanroom facilities at hospitals.
In your experience, how has robotic equipment overcome production challenges or expanded opportunities for new business?

More Flexible Electronic Manufacturing Means Better Medical Monitoring
To fit more reliably and comfortably when worn, wearable electronics must be flexible while retaining their ability to collect and communicate data. Conventional sensors and other electronic components, even when made very small, don’t often offer these attributes, which can limit their use as medical devices. A new additive manufacturing method from researchers at Harvard University’s Wyss Institute for Biologically Inspired Engineering makes it possible to create useful monitoring electronics that fit more comfortable and move naturally when worn directly on the skin.

Hybrid 3D Printing
Through a process that the researchers refer to as hybrid 3D printing, electronically conductive inks can be incorporated into wearable devices that are not only soft and flexible, and therefore comfortable to wear, but can also be stretched and still perform reliably. The conductive ink is made from thermoplastic polyurethane (TPU) and contains electrodes, which can be layered with a soft, flexible substrate through an additive manufacturing process. As the ink solidifies, the result is a conductive, highly flexible, and fully functional circuit that can be used for a range of medical needs.

Custom Fit For The Patient And Diagnosis
Since these soft sensors can be printed to just about any shape, and with the position of the conductive features determined during the manufacturing process, it’s possible to create medical sensory devices that fit the patient as well as the specific data to be collected. Researchers are able to collect information from a wearer’s movement or from the application of pressure and easily read the resulting data in a number of ways.
The hybrid 3d printing process has been noted as significant for the flexible and versatile devices it yields, as well as its relative low cost. While the resulting products are currently in the prototype stage, researchers have called this a first step in creating robust and affordable wearable electronics that are also comfortable and customized.

New Surgical Glue Could Render Stitches And Sutures Obsolete
When wounds are quickly and securely closed following injury, healing is faster, risks of infection are minimized, and more serious sustained injury can be prevented. A new type of surgical glue has been created to do that in a fast-acting and reliable manner. It may even change first aid and medical response procedures at car accidents, in combat zones, and at emergency sites.

Fast Forming For Better Wound Healing
MeTro behaves like a silicone sealant, much like those used to create a water seal in bathrooms and other household applications, but it works even faster. Once administered to human tissue, MeTro rapidly forms to gel-like thickness and serves to seal a wound. This action occurs as highly elastic proteins and light sensitive molecules are set after being exposed to UV light. The gel takes just 60 seconds to thicken and solidify, which is vital to blocking out bacteria in urgent situations.
Modifiable For Recovery Times
While MeTro securely remains in contact with the tissue to which it’s applied, it retains some elasticity so it moves with the patient and prevents wounds from reopening. The treatment can also be modified with a degrading enzyme that determines how soon MeTro will begin to breakdown. Whether sealing is required for minutes or months, the gel can be catered to appropriate recovery times.

For Use On Difficult To Treat Sites
Northeastern University and Australia’s University of Sydney Researchers responsible for creating MeTro have also shown how it can be used on treatment sites that are otherwise difficult to seal due to exposure to bodily fluids and natural expansion and contraction. The substance shows potential for use on vital areas that are challenging to stitch, suture, or bandage, such as internal organs like the lungs and heart.
As MeTro has been tested successfully on pigs, researchers are now focusing on trials in humans. Will their development render conventional wound healing and closing treatments obsolete? Comment and share your thoughts.
