Sustainable algal proteins, novel extraction techniques and applications in the bakery, dairy and pharmaceutical industries: A comprehensive review.

Microalgae have emerged as favorable substitutes for traditional animal-based proteins in the search for sustainable protein sources. Despite being underexplored, microalgae offer the possibility of large-scale protein production via novel extraction techniques. This review synthesizes current knowledge on microalgal proteins, shedding light on their novel extraction techniques and techno-functional properties, which are still in the early stages of exploration.

Revolutionizing Glucose Monitoring: Enzyme-Free 2D-MoS Nanostructures for Ultra-Sensitive Glucose Sensors with Real-Time Health-Monitoring Capabilities.

The growing requirement for real-time monitoring of health factors such as heart rate, temperature, and blood glucose levels has resulted in an increase in demand for electrochemical sensors. This study focuses on enzyme-free glucose sensors based on 2D-MoS nanostructures explored by simple hydrothermal route. The 2D-MoS nanostructures were characterized by powder X-ray diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and XPS techniques and were immobilized at GCE to obtain MoS-GCE interface.

Lemon extract supported green synthesis of bimetallic CuO/Ag nanoporous materials for sensitive detection of vitamin D3.

In modern era, deficiency of Vitamin D3 is predominantly due to limited exposure to sunlight and UV radiation resulting from indoor lifestyles. Several studies have revealed that vitamin D deficiency can lead to chronic vascular inflammation, diabetes mellitus, hypertension, congestive left ventricular hypertrophy, and heart failure. This study introduces a green synthesis of novel bimetallic nanoporous composite, CuO/Ag using lemon extract.

Graphene-amplified femtosensitive aptasensing of estradiol, an endocrine disruptor.

We report the construction of a novel electrochemical femtomolar aptasensing APT-ERGO/GCE interface based on the covalent immobilization of 38-mer amine-functionalized (NH2-APT) 17β-estradiol (E2) DNA aptamers on a graphene amplifying platform. Graphene oxide (GO) was synthesized and characterized by using FTIR, UV-vis spectroscopy, XRD spectroscopy, and SEM technique. The strategy for the construction of the E2-aptasensing interface involves in a three-step modification process.

Next generation NIR fluorophores for tumor imaging and fluorescence-guided surgery: A review.

Cancer is a group of diseases responsible for the major causes of mortality and morbidity among people of all ages. Even though medical sciences have made enormous growth, complete treatment of this deadly disease is still a challenging task. Last few decades witnessed an impressive growth in the design and development of near infrared (NIR) fluorophores with and without recognition moieties for molecular recognitions, imaging and image guided surgeries.

Polycyclodextrin and Carbon Nanotubes as Composite for Tyrosinase Immobilization and Its Superior Electrocatalytic Activity Towards Butylparaben an Endocrine Disruptor.

We developed a protocol for the immobilization of tyrosinase (Tyr) on the composite of polycyclodextrin polymer (CDP) and carbon nanotubes for the detection of an endocrine disruptor, i.e., butylparaben (BP).

Voltammetric quantitation of nitazoxanide by glassy carbon electrode.

The present study reports voltammetric reduction of nitazoxanide in Britton-Robinson (B-R) buffer by cyclic and square-wave voltammetry at glassy carbon electrode. A versatile fully validated voltammetric method for quantitative determination of nitazoxanide in pharmaceutical formulation has been proposed. A squrewave peak current was linear over the nitazoxanide concentration in the range of 20-140 µg/mL.

Carbon nanotubes based electrochemical aptasensing platform for the detection of hydroxylated polychlorinated biphenyl in human blood serum.

A novel strategy to sense target molecules in human blood serum is achieved by immobilizing aptamers (APTs) on multi-walled carbon nanotubes (MWCNT) modified electrodes. In this work, the aminated aptamer selected for hydroxylated polychlorinated biphenyl (OH-PCB) was covalently immobilized on the surface of the MWCNT-COOH modified glassy carbon electrode through amide linkage. The aptamers function as recognition probes for OH-PCB by the binding induced folding of the aptamer.

Rapid microwave synthesis of high aspect-ratio ZnO nanotetrapods for swift bisphenol A detection.

Highly crystalline and high aspect-ratio ZnO nanotetrapods were grown by a novel and swift microwave synthesis. FESEM analysis revealed that each tetrapod has four thin arms and are derived from the midst of the crystal. The diameter of each arm is larger at the base and smaller at the tip.

A biosensor fabricated by incorporation of a redox mediator into a carbon nanotube/nafion composite for tyrosinase immobilization: detection of matairesinol, an endocrine disruptor.

An electrochemical matairesinol biosensor was fabricated by immobilizing tyrosinase on a poly(thionine)/nafion/multi-walled carbon nanotube composite film. A polymeric film of the redox dye thionine enables the stable immobilization of tyrosinase while acting as a mediator for the enzymatic process has been incorporated into the carbon nanotube/nafion composite film. The immobilization method is based on crosslinking of the tyrosinase layer with an electropolymerized film of poly(thionine).

Voltammetric determination of antibacterial drug gemifloxacin in solubilized systems at multi-walled carbon nanotubes modified glassy carbon electrode.

A sensitive electroanalytical method for determination of gemifloxacin in pharmaceutical formulation has been investigated on the basis of the enhanced electrochemical response at multi-walled carbon nanotubes modified glassy carbon electrode in the presence of CTAB.
