#Actuators that mimic ice plants Engineers developing moveable robot components may soon take advantage of a trick plants use.
The new findings could serve as a basis for designing moveable components with especially natural mobile properties, for example for applications in robots.
the antimalarial garment can be worn during the day to provide extra protection and does not dissipate like skin-based repellants.
and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin,
greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.
limiting the risk to the environment. eople have been interested in using silver nanoparticles for antimicrobial purposes, but there are lingering concerns about their environmental impact due to the long-term effects of the used metal nanoparticles released in the environment,
INVISTA Professor of Chemical and Biomolecular engineering at NC State and the paper corresponding author. e show here an inexpensive and environmentally responsible method to make effective antimicrobials with biomaterial cores. he researchers used the nanoparticles
Alexander Richter, the paper first author and an NC State Ph d. candidate says that the particles could be the basis for reduced risk pesticide products with reduced cost
Richter said. e may include less of the antimicrobial ingredient without losing effectiveness while at the same time using an inexpensive technique that has a lower environmental burden.
#New material opens possibilities for super-long-acting pills Medical devices designed to reside in the stomach have a variety of applications,
including prolonged drug delivery, electronic monitoring, and weight-loss intervention. However, these devices, often created with nondegradable elastic polymers, bear an inherent risk of intestinal obstruction as a result of accidental fracture or migration.
including orally delivered capsules that can release drugs over a number of days, weeks, or potentially months following a single administration.
or extended-release drug-delivery systems that could last for weeks or months after a single administration. his delivery system provides a flexible and smooth external covering that slowly disintegrates,
which could release drugs or small devices for monitoring and imaging the GI TRACT, says Edith Mathiowitz,
In particular, the authors say they are excited for the drug-delivery applications of this technology. With further work in adjusting the polymer composition or the design of the system
they say that they could tailor devices to release drugs over a specific timeframe of up to weeks or months at a time.
MIT is negotiating an exclusive license agreement with Lyndra, an early-stage biotechnology company developing novel oral drug-delivery systems,
Ie not seen previously enabling patients to swallow a single pill that can then act for whatever length of time is desired,
Such single-administration events could improve medication adherence, which remains a major clinical barrier. According to the World health organization
Medication nonadherence costs the U s. an estimated $100 billion every year, the bulk of which comes in the form of unnecessary hospitalizations.
