Abstract Electroanalytical and optical techniques are widely used in the development of nanomaterials-based sensor platforms. These have a quick response, high sensitivity, selectivity. nanomaterial-based sensors must be able to detect biomarkers, pathogens, toxins, pharmaceuticals biological matrices associated with cardiovascular disease, cancer, neurodegenerative diseases. Considering these ...

Electrochemical biosensing systems coupled with graphene quantum dots (GQDs) have demonstrated suitability for cancer diagnostic strategies, particularly to identify the changes facilitating early phases of tumorigenesis as well detect ultralow concentrations biomarkers that distinguish between normal and malignant cells. GQDs, known a novel class zero-dimensional semiconductor nanocrystals, ar...

We report an inexpensive TiO2 based quantum dot solar cell (QDSSC) with improved power conversion efficiency prepared by simple techniques. Barium doped zinc sulfide has been successfully deposited on cadmium dots (QDs) successive ion layer adsorption and reaction (SILAR) technique. The is utilized as a passivation in the QDSSC, which helped better charge separation. copper (Cu2S) reduced graph...
