Soft X-ray method promises nanocarrier breakthroughs

Before the huge potential of tiny nanocarriers for highly targeted drug delivery and environmental clean-up can be realized, scientists first need to be able to see them

27-May-2021 - Currently researchers have to rely on attaching fluorescent dyes or heavy metals to label parts of organic nanocarrier structures for investigation, often changing them in the process. A new technique using chemically-sensitive "soft" X-rays offers a simpler, non-disruptive way of gaining insight ...

Secure nano-carrier delivers medications directly to cells

Nanoparticles with synthetic DNA can control release of drugs

30-Sep-2020 - Medications often have unwanted side-effects. One reason is that they reach not only the unhealthy cells for which they are intended, but also reach and have an impact on healthy cells. Researchers at the Technical University of Munich (TUM), working together with the KTH Royal Institute of ...

Cancer identity technology makes it easier to find a tumor's 'address'

20-Nov-2018 - Purdue University researchers have developed a technology aimed at making it easier to deliver cancer treatment to the right "address" in the body while also easing the painful side effects of chemotherapy on patients. One of the big issues with chemotherapy is that most treatment approaches ...

New flexible, transparent, wearable biopatch, improves cellular observation, drug delivery

Minimally invasive patch delivers exact doses directly into cells, lessens pain, toxicity

12-Nov-2018 - Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities."This means that eight or nine silicon nanoneedles can be injected into a single cell ...

Scientists capture colliding organic nanoparticles on video for first time

20-Nov-2017 - A Northwestern University research team is the first to capture on video organic nanoparticles colliding and fusing together. This unprecedented view of "chemistry in motion" will aid Northwestern nanoscientists developing new drug delivery methods as well as demonstrate to researchers around the ...

The stickiness of molecules

What we could not measure before

18-May-2017 - When building with molecules, it is important to understand how they stick to each other. The problem is that the methods used to measure this are themselves an influencing factor on the process. Researchers at TU Eindhoven, led by Professor Bert Meijer, present a method that excludes this ...

Triple-threat cancer-fighting polymer capsules for guided drug delivery created

04-Apr-2017 - Chemists at the University of Alabama at Birmingham have designed triple-threat cancer-fighting polymer capsules that bring the promise of guided drug delivery closer to preclinical testing. These multilayer capsules show three traits that have been difficult to achieve in a single entity. They ...

When push comes to shove: Size matters for particles in our bloodstream

06-Oct-2016 - Researchers at the University of Connecticut have uncovered new information about how particles behave in our bloodstream, an important advancement that could help pharmaceutical scientists develop more effective cancer drugs. Making sure cancer medications reach the leaky blood vessels ...

Nano shake-up

UD researchers demonstrate that processing can affect size of nanocarriers for targeted drug delivery

16-Apr-2014 - Significant advances have been made in chemotherapy over the past decade, but targeting drugs to cancer cells while avoiding healthy tissues continues to be a major challenge. Nanotechnology has unlocked new pathways for targeted drug delivery, including the use of nanocarriers, or capsules, that ...
