By selecting a specific type on the basis of its pore shape, we were able to convert lactic acid directly into the building blocks for PLA without making the larger by-products that do not fit into the zeolite pores.
It may also help identify rare mutations and subtypes of infectious diseases as well as drug-resistant strains.
Lubricant base oils can produce even more greenhouse gas emissions on a per-mass basis than petroleum-derived fuels
and carry payloads of pharmaceutical drugs to targeted tissues. However, when usual methods to produce carbon nanoparticles are rather complex
They used spectroscopy to confirm the formulation as well as visualize the delivery of the particles and drug molecules.
The experiment showed that the carbon nanoparticles did not release the drug payload at room temperature
They began to release the anticancer drug only at body temperature. Scientists also found that they can alter the infusion of the particles into melanoma cells by adjusting the polymer coatings.
Study showed that cancer cells were affected positively by drugs delivered by these carbon nanoparticles. These carbon nanoparticles,
They can be used to carry a variety of different drugs into a human body. It is a very versatile platform to treat melanoma, other kinds of cancers and other diseases.
as well as to make it carry several different drugs at the same time to allow for a multidrug therapy with the same particles.
and tune them to release the drugs in the presence of the cellular environment. This is a great achievement,
which will eventually lead to innovative drug therapies for cancer and other diseases i
#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.
