How engineered nanoparticles are affecting the treatment of wastewater
In recent years, engineered nanoparticles (ENPs) have been incorporated into a variety of consumer products such as technology, cosmetics, pharmaceuticals and clothing to name but a few. ENPs can be defined as intentionally created particles sized 1-100
Unmet clinical needs in the treatment of systemic fungal infections. Reformulating repurposed drugs such as amphotericin B
A recent increase in the frequency of fungal infections has led to a higher number of fungal species that can cause these pathologies, as well as a decrease in the number of effective treatments against them due
Nanosensor for diabetes management
Diabetes is a major health concern for millions around the world. In addition to the analysis of free glucose level in blood, glucose bound to haemoglobin (HbA1c) is considered to be a very useful diagnostic marker for
Electrically controlled insulin release
Stimuli responsive materials are promising for designing the next generation of drug delivery systems. Such materials would enable drugs to be released on-demand or in response to patient needs, specifically at the target site, minimizing side effects.
Metal nanoparticles wire up nanowires for better battery materials
New materials are making advancements in higher power, longer life and faster charging batteries a reality. These improvements have been driven by the uptake in electric vehicles and a host of other applications that require long life
Getting health allies from agriculture enemies
In recent years, research in nanotechnologies has demonstrated that nanometer-sized particles constructed using a wide array of materials (e.g. metals, lipids, polymers, proteins) can offer answers to unmet questions concerning drug/vaccine delivery. Ideally, these systems should prevent
Gold-silver nanoparticles instead of traditional diabetic drugs
Recently, we have published a pioneering work on green biosynthesis and complete characterization of gold and core shell silver-gold nanoparticles (AuNPs and Ag@AuNPs) via using green biopolymer in the influence of microwave radiation. These synthesized nanoparticles provide
Inhaled metal oxide nanoparticles’ retention in the pulmonary tissue can be hindered by their relatively high solubilization counterbalancing their unfavorable action on the free pulmonary cells response
We hypothesized that pulmonary clearance vs. retention of metal oxide nanoparticles (NPs) is controlled not only by activity of phagocytes and other physiological mechanisms but also by the NP solubilization which, in some cases, may even prevail
Enzymes digestible nanoparticles: a new generation of biodegradable drug delivery nanosystem
Pathologies with high death rates such as cancers may well have found their solutions with the rise of nanotechnology. Nanotechnology is a newly coined word encompassing the application of nanoparticles for all kinds of technological challenges. A
Interaction of ZnO nanoparticle with biological system
Zinc oxide nanoparticles (ZnO NPs) are one of the few nanoparticles synthesised industrially. This nanoparticle possesses a broad spectrum of application in rubber industry, optoelectronics, biomedical sector and pharmaceutics. With extensive applications the exposure risk also increases
Multidimensional screening anti-counterfeiting: shapes and images
Multidimensional anti-counterfeiting technique, which could display diverse images depending on different readout conditions, provides an unparalleled approach to improve the information security and holds great potential in practical applications. Although it has been achieved by varied wavelength,
Amazing events in a glass of water
Have you ever thought about what happens when a pill which has to treat for example your headache, is immersed into water (or any other fluid) and sinks to the bottom of a glass? A number of
Design of supplements and nutraceuticals enriched in resveratrol: a promising natural compound
Resveratrol is a polyphenol compound found in grapes, red wine, berry fruits and nuts. Given the favorable prophylactic and therapeutic effects of resveratrol, nanocarriers have been developed for enhancing its bioavailability for further application as supplements or
Versatile fabrication for aerogels by freezing and subsequent freeze-drying of nanoparticle solutions
Aerogels are fascinating materials because they are lightweight, highly porous and exhibit huge surface areas. They consist of more than 99% air, while the rest is a well interconnected network of small inorganic or organic particles or
How to avoid cisplatin associated hearing-loss using nanoparticles
Cisplatin (CDDP) is a highly effective chemotherapeutic agent against a variety of solid tumors including head and neck, lungs, ovary, bladder and testicles, however, it presents severe side-effects that affect kidney function, nervous system and hearing. There
Direct monitoring of the interaction between ROS and cerium dioxide nanoparticles in living cells
Swallowing the pill we don’t know whether it comes to the target, destroys the harmful objects (microbes, viruses, cancer cells) and/or whether it works correctly at the center of the inflammation. Let’s imagine that each grain of
