Development of thermoelectric gas sensor for breath analysis: How can we improve the gas selectivity?

Breath gas contains a range of marker gases that can be associated with disease and metabolism. For instance, the monitoring of breath H2 is useful for measurement of orocecal transit time, colonic fermentation, abnormal fermentation and irritable

An efficient, water soluble and biocompatible sensor for the detection of PPi and application in cancer diagnosis

Detection of pyrophosphate anion (PPi) has become an important area of research due to its chemical and biological significance especially in early cancer diagnosis. PPi involves in various biological processes (ATP hydroloysis, cellular metabolism, DNA & RNA

Paper-based sensor for on-site detection of hydrogen sulfate in water

In 2013 UNICEF reported that ca. 2200 children below 5 years old die every day of diarrheal diseases. This report also indicates that around 90% of these deaths are the consequence of unsafe drinking water. The detection

Recent advances in gold nanoparticle-based optic sensor

The ease in preparation and conjugation, stability, biocompatibility, as well as the size-dependent optical properties makes gold nanoparticles (Au NPs) one of the most popular nanomaterials for sensing of analytes of interest in the last decade. We

Genes regulating Wolbachia cell division

Bacterial infection underlies many devastating diseases, yet bacteria also play a central role in the maintenance of human health and well-being.  From aiding in host food digestion and limiting unfavorable bacterial growth to causing paralysis or even

Selective naked-eye sensors for real time detection of mercury ion in water

Mercury (Hg) is one of the most harmful and toxic chemical pollutants, which is released into the environment through natural or industrial sources. This dangerous heavy metal has the ability to enter the food chain and accumulate

Sensory deprivation early in life has lasting impacts

What happens to a brain area when it is underutilized when a person or animal is growing up? Does this kind of deprivation of experiences lead to negative effects for brain development? For a long time, the

Detecting biological hydrogen sulphide gas using metal-organic frameworks

Remember the unpleasant smell of boiled egg? It’s a Hydrogen Sulphide(H2S) an infamous flammable gas known for its smell and toxic effects.The exposure to H2S causes loss of sense of smell (Olfactory Paralysis) while the prolong exposure

Silver clusters change form and color with each atom

Metal clusters are particles consisting of a few (usually between 2 and 100) metal atoms. Very often, metal clusters possess properties that differ markedly from both the constituting atoms and the bulk. Furthermore, they show nonscalable size

New generation Opto-Electronic Patch Sensor (OEPS): CareLight

In recent decades, the number of people suffering from chronic diseases has increased dramatically. Referring to the report of British Heart Foundation (BHF), almost 2.6 million people in the UK are living with heart and circulatory disease.

Bees get their ‘fix’ in virtual reality

How does a small insect, with its tiny eyes and brain, see the world it moves through? Obviously an insect can’t answer our question directly, so scientists have developed other means to uncover the answers. One approach
