Bioinspired light-responsive materials for on-demand drug delivery

Filippo Pierini and his team are developing smart nanoplatforms with enhanced biocompatibility that allows for more carefully controlled drug delivery within the body within the body over time

Polymer-based nanomaterials represent one of the most innovative and promising approaches in modern biomedical applications, including cancer and antibacterial therapy. They offer the ability to control the delivery of specific drugs within the human body. Their practical application, however, faces many challenges, for instance low tumour penetration in cancer or low drug internalisation in the case of antimicrobials. Professor Filippo […]

Advanced chemiresistive materials for wireless sensor networks

When exposed to gases and vapours of certain chemicals in their surrounding environments, chemiresistive materials can change their electrical resistance, which makes them incredibly useful as sensors for air pollution. Through her work, Dr Esther Hontañón, a researcher at the Spanish Council of Research (CSIC) in Madrid, explores how the latest advances in materials science and 3D printing technology can […]

The nanotechnology revolution is fuelled by the versatility of nanomaterials. Changing a nanomaterial’s composition and structure alters its properties, rendering nanomaterials tailor-made for specific applications. Mathematical modelling guides researchers towards predicting desired behaviour prior to experimentation. Titus Masese of the National Institute of Advanced Industrial Science and Technology (AIST) and Godwill Kanyolo of the University of Electro-Communications (UEC), in Japan, […]

Electron emission patterning: A new path towards smaller devices?

Electron emission patterning A new path towards smaller devices

The demand for smaller and more powerful electronic devices is ever growing in many sectors of today’s society. Current technology limits how small devices can be. To develop smaller devices, new materials and manufacturing techniques are needed. Ali Aliev and Ray Baughman of the Alan G. MacDiarmid NanoTech Institute have developed a non-contact dry patterning technique for carbon nanotubes. Their […]

Cellulose nanodefects: The key to biofuels and biomaterials of the future

Cellulase enzymes use defects as ‘stepping stones’ to initiate degradation of cellulose fibre.

Cellulose is a renewable polymer that can be used to produce biofuels and other bio-based materials. However, the potential of cellulose to displace petroleum-derived products had been limited by incomplete knowledge of its nanoscale characteristics. Recent research by Dr Peter Ciesielski and Dr Michael Crowley, both from the National Renewable Energy Laboratory, has advanced our understanding of nanoscale defects that […]

Polymeric transformer: Nanoantibiotics for drug-resistant infections

Polymeric transformer: Nanoantibiotics for drug-resistant infections

The translational research of Professor Young Jik Kwon at the University of California, Irvine aims to fill a formidable void created by the lack of available effective antibiotics. Combining naturally-occurring antimicrobial substances with conventional antibiotics, Professor Kwon’s nanoantibiotics are a novel generation of compounds molecularly engineered to safely and effectively target drug-resistant bacteria. One of his current projects aims to tackle […]

Laser ablation in liquid: A powerful route to new nanoparticle catalysts

Dr Katharine Tibbetts (Virginia Commonwealth University) has been developing a novel approach for the synthesis of metal nanoparticles, based on a reactive laser ablation in liquid technique. She uses ultra-short laser pulses to ionise water molecules and generate a highly energetic plasma of electrons capable of reducing soluble metal ions to neutral atoms, which then coalesce to generate a nanoparticle […]
