Managing diabetes with 3D nanostructured

Researchers have synthesized a sensitive nanosensor that can monitor the blood glucose levels though glycated hemoglobin (HbA1c) detection. HbA1c monitoring is very useful for patients suffering from Diabetes which provide patients to plan for their quantity and

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

When graphene meets lectin for sensitive glycan analysis

The importance of glycans (chains of carbohydrates) in human body is relatively well known. They have a number of essential roles not only in physiology, but also in origin of various diseases. The majority of proteins and

The application of biosensors for meat quality analysis

To meet the demands of growing meat consumption in recent years, animal farming tended to increase meatiness. The rise of meatiness was not in concordance with the improvement of the meat quality. The quality of meat is

The earlier, the better and the controlled. Glucose level sensing in diabetic patients through nano biosensors

Gone are the days when there was a big pain for patients suffering from high blood glucose (blood sugar) level that early and rapid detection was a long wait & rather unpleasant. Now recently developed approaches using

Ultrasensitive detection and glycan analysis of a prostate cancer biomarker

In recent years we have seen an increased frequency of diagnosed prostate cancer (PCa) cases accompanied with an enhanced mortality worldwide. Symptoms of an early-stage PCa can be mild or even absent, thus there is an urgent

Imaging of viruses with the help of surface plasmons

For a long time biosensors based on the surface plasmon resonance (SPR) phenomenon were not considered as effective tools to detect and visualize the binding of individual nano-scale objects to the functionalized sensor surface. However, innovative studies

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

Chemesthesis affects taste

The sensations of taste, which are divisible into several distinct qualities: sweet, sour, bitter, salty, umami, and possibly fatty, play an important role for accepting or rejecting food and serve to protect us from ingesting harmful substances,

A electrochemical biosensor for the detection of antibodies against avian influenza virus type H5N1 in hen sera

Avian influenza (AI) is a highly contagious disease caused by Orthomyxoviridae family viruses. Highly pathogenic avian influenza (HPAI) virus can be easily transmitted between poultry, leading to severe disease outbreaks or even pandemics. It is difficult to

The new photoelectrochemical aptamer biosensor

The photoelectrochemical (PEC) biosensing is a new and promising analytical technique to detect biomolecules with high sensitivity. As core unit of PEC biosensor, photoelectrode materials play an irreplaceable role for its detecting performance. Among them, titanium dioxide
