Nobel Prize in Chemistry 2023 goes to quantum dots, which illuminated the path to nanotechnology

Oct. 4, 2023
By Mar de Miguel
Quantum dots, a phenomenon in quantum physics that alters the energy of electrons and changes the properties of particles, caught the attention of the Royal Swedish Academy of Sciences (KVA) for the 2023 Nobel Prize in Chemistry. Alexei Ekimov and Louis Brus received the award for their discovery; Moungi Bawendi, for developing its applications. With their work, “in equal shares,” said the Secretary General of KVA Hans Ellegren, the three scientists have laid the foundations of nanotechnology, a tool that we see today in our homes, on televisions and LED lamps, or in laboratories and hospitals for designing new drugs or new strategies against cancer.

Synthetic cell junctions allow tissue reconstruction

Dec. 13, 2022
By Mar de Miguel
A combination of bioengineering techniques on normal cell binding proteins could be the method of the future for selective cell binding. Scientists at the University of California, San Francisco (UCSF) have created a synthetic glue based on the expression of membrane receptors to establish the desired connection between cells. The results may be applied in different fields of cell biology or biomedicine, such as regeneration and wound repair, including the nervous system, or cancer.

Bioengineered multifunctional exosomes evoke cancer immunity

Sep. 14, 2022
By Mar de Miguel
The design of genetically modified exosomes that combine multiple targets killed cancer cells and conferred immunity against them. Scientists at the University of Southern California (USC) applied bioengineering techniques to introduce up to four antitumor functions in the same type of extracellular vesicles and destroy EGFR-positive triple-negative breast cancer (TNBC) tumor cells.

Researchers are testing a new generation of implantable nanodevices used in myocardial infarction

Feb. 4, 2022
By Bernard Banga
PARIS – An interdisciplinary academic research consortium in Italy has devised and tested nanowires that restore physiological cell-to-cell conductance. This research team, led by the Experimental and Applied Medical Technology Lab (Tecmed Lab) at the Department of Medicine and Surgery at the University of Parma, Italy, has just published the results of multiple local in situ injections of nanowires into left ventricular infarct regions in Nature Communications.

3D ‘pop-up’ sensors measure cardiac signals inside a single heart cell

Jan. 7, 2022
By David Godkin
University of California San Diego engineers have developed tiny 2D sensors that pop up to become a 3D assemblage of microscopic sensors for directly measuring the movement and speed of electrical signals inside the heart. According to nanoengineering professor Sheng Xu, the nanotechnology has enormous implications for heart doctors anxious to better diagnose and treat arrhythmia, heart attack and other diseases.

Virus trap: Early stage nanoshell tech aims to neutralize viruses

Aug. 2, 2021
By Bernard Banga
PARIS – At some point, scientists reported, it may be possible to quarantine viruses rather than humans. For the last two years, European research consortium Virofight has been working on a form of nanotechnology intended to neutralize viruses such as SARS-CoV-2, HIV, influenza and hepatitis viruses.
