“…The high scientific activities around this material can be expressed with around 2000 research articles in the last twenty years (source: web of science, keywords: nanocomposites and biosensor). This technology even became of interest for commercialised devices where a couple of nanobiosensors are already in clinical use [98] Here, some recent original examples are summarized since there are already excellent exhaustive review articles about the different nanocomposites for health care biosensing [99][100][101].…”

Biosensors are essential tools in the health and the environmental sectors since they allow fast and reliable diagnostics and analysis. Biosensors are defined by the biological sensing element, which contains biomolecules or synthetic, bioinspired entities with unique specificity towards the analyte. The biological or bioinspired recognition even can be transduced into an electric, electrochemical, or optical signal. A constant challenge for the development of biosensors is the confinement of these selective entities in devices without altering the biological activity. Polymers are great candidates to serve as substrates for the immobilization or entrapment of bioreceptors related to well established synthesis routes with highly modulable chemical functions to create an almost ideal environment for the biomolecules. Nanomaterials are of constant increasing interest since they allow not only to increase drastically the specific surface for higher amounts of receptor units, but also provide electric or optical properties leading to enhanced signal capture. As for bioreceptors, such nanomaterials can be integrated polymer matrices for reliable processability. This review aims to summarize selected original examples about biosensors for health monitoring using beneficial combinations of nanomaterials and polymers.

“…Therefore, replacement and recalibration of these sensors are another challange in this field. When designing a nanomaterial based biosensors, it should be considered to be novel, rapid, low cost, on site and multiple testing properties (D'Souza et al, 2017). This section of the review summarizes the significance of composite nanomaterial based biosensors for biomedical applications.…”

“…The upconversion nanoparticles (UCNPs) are an important optical material with the ability to convert NIR into UV by antistoke emission. , In biology, UCNPs have been gifted the luxury of deep tissue penetration, UV-activated opening of drug gates, folate target activation, photodynamic therapy in bone cell monitoring, and in vivo cancer imaging . But UCNPs have not found application in food and nutrition studies so far to our knowledge; sensors are the exceptions. , …”

“…31 But UCNPs have not found application in food and nutrition studies so far to our knowledge; sensors are the exceptions. 32,33 Hence, the objective of the present study is to develop an UCNP disk having maximum UV emission to plug into the mushroom for efficient ergosterol to vitamin D conversion with the assistance of solar irradiation. The casting of UCNPs into a disk pose engineering challenges hence it needs careful optimization as in the case of fibers.…”

Mushrooms are rich in ergosterol, a precursor of ergocalciferol, which is a type of vitamin D2. The conversion of ergosterol to ergocalciferol takes place in the presence of UV radiation by the cleavage of the “B-ring” in the ergosterol. As the UV radiation cannot penetrate deep into the tissue, only minimal increase occurs in sunlight. In this study, upconversion nanoparticles with the property to convert deep-penetrating near-infrared radiation to UV radiation have been cast into a disk to use sunlight and emit UV radiation for vitamin D conversion. An engineered upconversion nanoparticle (UCNP) disk with maximum particles and limited clusters demonstrates ∼2.5 times enhanced vitamin D2 conversion.
