Gold nanoclusters with five discrete sizes (Au4, Au8, Au10, Au13, and Au25) are synthesized in a protein template with predefined conformation via a CO-mediated synthesis.

Objective(s): A novel technique for the early diagnosis of breast cancer involves the use of nanoparticles (NPs). The present study aimed to use gold NPs to assess the variations in light source transfer intensity. Materials and Methods: Blood samples with hemoglobin (Hb) concentrations of ×1, ×2, and ×4 were used to simulate normal and cancerous conditions in the breast. Spherical gold N...

We have developed a Boolean NAND logic gate for the fluorescent detection of nitrite ions by using bovine serum albumin (BSA) functionalized gold nanoclusters.

The ligand-to-metal charge transfer in gold nanoclusters gets influenced by the interacting lipid that regulates photoinduced electron aqueous medium.

Epigenetic modifications sit 'on top of' the genome and influence DNA transcription, which can force a significant impact on cellular behavior and phenotype and, consequently human development and disease. Conventional methods for evaluating epigenetic modifications have inherent limitations and, hence, new methods based on nanoscale devices are needed. Here, we found that antioxidant (glutathi...

background: breast cancer is the most common type of cancer in women demanding time and accurate diagnosis to take remedial measures to treat. objective: comparing the diagnostic capability of the computer regulation thermography (crt), as a novel and safe dignostic procedure, with common clinical examination and imaging methods including sonography and mammography for diagnosing breast cancer ...

Recent advances in nanoscience have led to the development of numerous methodologiesfor controlled synthesis of mono dispersed nanoparticles and/or nanoclusters via surface stabilization by organic capping ligands. The application of these nanoparticles in catalysis and other fields often requires the removal of organic ligands. It is known that the removal of organic capping agents or or...

Focusing on size-selected gold clusters consisting of up to 20 atoms, that is, in the size regime where properties cannot be obtained from those of the bulk material through scaling considerations, we discuss the current state of understanding pertaining to various factors that control the reactivity and catalytic activity of such nanostructures, using the CO oxidation reaction catalyzed by the...
