Ti3C2-MXene based fluorescent biosensor for rapid detection of lung cancer biomarker
Over the last decade, zero-dimensional (0D) and two-dimensional (2D) nanomaterials such as nanostructured metals, and graphene derivatives delivered an extraordinary impact as fluorescence quenchers or energy acceptors in developing fluorescent biosensors. However, these OD/2D materials have a
Photonic biosensors for mycotoxin detection in milk
Contamination of food and agricultural products by various types of toxigenic molds (fungi) is a serious and global problem. Fungal toxins, in particular, mycotoxins produced by several species of fungi are naturally present in food species such
Biomimetic approach for an artificial nose
The dream of monitoring odours is certainly very old, but only recently scientists have come-up with realistic approaches and proposals. As soon as the olfactory system started to reveal its secrets and the specific sensing elements (the
Enrichment, quantification and glycan analysis of prostate cancer oncomarker in a single step
In recent decades, there is an increasing trend in prostate cancer occurrence and mortality worldwide, caused partly by a more available diagnostics, prolonged life period but also increased risk factors present in the environment. Most commonly, age
Novel biosensors for the rapid detection of toxicants in foods
The specific objective of this monograph is mainly to exploit progress in nanosciences to deploy nanotechnology in affordable, mass-produced sensors, and to integrate these into components and systems (including portable ones) for mass market applications in environmental
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
