Waterproof superglue may be strongest in nature
April 12, 2006Bacterial adhesive is 2-3 times stronger than common commercial glues
The glue one species of water-loving bacteria uses to grip its surroundings may be the strongest natural adhesive known to science. If engineers can find a way to mass-produce the material, it could have uses in medicine, marine technology and a range of other applications.
Researchers at Indiana University in Bloomington and Brown University in Providence, R.I., studied how much force they needed to tug the tiny, stalked Caulobacter crescentus off a glass plate. As the researchers reported in the Apr. 11, 2006, Proceedings of the National Academy of Sciences, the bacteria grip with a force of 70 newtons per square millimeter-roughly 5 tons per square inch-or equivalent to the downward force exerted by three cars balancing on a spot the size of a quarter. While the researchers do not yet know if the substance is the strongest glue on Earth, it is stronger than cyanoacrylate superglues found on store shelves and may be rivaled only by a few synthetics.
Several NSF programs have supported the research. Funding for this study came from the Division of Materials Research in the Mathematics and Physical Sciences Directorate.

When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells.
Surgeon 'gluing' the breastbone together after open-heart surgery
An innovative method is being used to repair the breastbone after it is intentionally broken to provide access to the heart during open-heart surgery. The technique uses a state-of-the-art adhesive that rapidly bonds to bone and accelerates the recovery process.
Laser etching safe alternative for labeling grapefruit
Laser labeling of fruit and vegetables is a new, patented technology in which a low-energy carbon dioxide laser beam is used to label, or "etch" information on produce, thereby eliminating the need for common sticker-type labels.
New American Chemical Society podcast: Tiny sea creature and a new medical adhesive
Scientists questing after a long-sought new medical adhesive describe copying the natural glue secreted by a tiny sea creature called the sandcastle worm in the latest episode in the American Chemical Society's (ACS) award-winning podcast series, "Global Challenges/Chemistry Solutions."
Super sticky barnacle glue cures like blood clots
Barnacles are a big problem for boats. Adhering to the undersides of vessels, carpets of the crustaceans can increase fuel consumption by as much as 25%.
Micropatterned material surface controls cell orientation
Cells could be orientated in a controlled way on a micro-patterned surface based upon a delicate material technique, and the orientation could be semi-quantitatively described by some statistical parameters.
Study shows how disruption of spectrin-actin network causes lens cells in the eye to lose shape
A network of proteins underlying the plasma membrane keeps epithelial cells in shape and maintains their orderly hexagonal packing in the mouse lens, say Nowak et al.
Building better bone replacements with bacteria
Bacteria that manufacture hydroxyapatite (HA) could be used to make stronger, more durable bone implants. Professor Lynne Macaskie from the University of Birmingham this week (7-10 September) presented work to the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh.
The invasive green mussel may inspire new forms of wet adhesion
The green mussel is known for being a notoriously invasive fouling species, but scientists have just discovered that it also has a very powerful form of adhesion in its foot, according to a recent article in the Journal of Biological Chemistry.
Pitt researchers harness carbon nanomaterials for drug delivery systems, oxygen sensors
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.
