Microneedles: Nano-sized, huge impact
Drug delivery, blood extraction, contrast agent injection – many procedures in modern medicine would be utterly impossible without needles. Despite the benefits, inserting pointy metal tubes into a patient also comes with several drawbacks. By downscaling the to micrometer-size, Japanese researchers open even more areas of application for needles, while bypassing some of the most important…

No more needles for bloodtests?
Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19, or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and…

"Micropores": A new way to deliver drugs through the skin
Scientists from Nanyang Technological University, Singapore (NTU Singapore) and the Agency for Science, Technology and Research (A*STAR) have showed that applying “temporal pressure” to the skin of mice can create a new way to deliver drugs. In a paper published in Science Advances, the researchers showed that bringing together two magnets so that they pinch and apply pressure to a fold of…

Nano-patch stores medical information under the skin
Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. One factor that makes vaccination campaigns in those nations more difficult is that there is little infrastructure for storing medical records, so there’s often no easy way to determine who needs a particular vaccine. Researchers at the Massachusetts Institute of Technology (MIT)…

ELSAH: A wearable to determine biomarkers
The EU four-year project ELSAH, which began at the dawn of 2019, aims to design a wearable to enable continuous determination of biomarker concentrations. Project coordinator Dr Joerg Schotter, Molecular Diagnostics, Centre for Health & Bioresources, AIT Austrian Institute of Technology GmbH, explains the project’s objectives and potential applications for the planned wearable.

New findings could improve STI vaccinations
In a new study, researchers from King’s College London have shown how skin vaccination can generate protective CD8 T-cells that are recruited to the genital tissues and could be used as a vaccination strategy for sexually transmitted infections (STIs), such as HIV or herpes simplex virus.

Diabetes: Smart insulin patch could replace painful injections
Painful insulin injections could become a thing of the past for the millions of Americans who suffer from diabetes, thanks to a new invention from researchers at the University of North Carolina and NC State, who have created a “smart insulin patch” that can detect increases in blood sugar levels and secrete doses of insulin into the bloodstream whenever needed.
