Carbon dots: a novel platform for biomedical applications.

Carbon dots (CDs) are a recently synthesised class of carbon-based nanostructures known as zero-dimensional (0D) nanomaterials, which have drawn a great deal of attention owing to their distinctive features, which encompass optical properties (., photoluminescence), ease of passivation, low cost, simple synthetic route, accessibility of precursors and other properties. These newly synthesised nano-sized materials can replace traditional semiconductor quantum dots, which exhibit significant toxicity drawbacks and higher cost.

Nanoassembled Peptide Biosensors for Rapid Detection of Matrilysin Cancer Biomarker.

Early detection of cancer is likely to be one of the most effective means of reducing the cancer mortality rate. Hence, simple and ultra-quick methods for noninvasive detection of early-stage tumors are highly sought-after. In this study, a nanobiosensing platform with a rapid response time of nearly 30 s is introduced for the detection of matrilysin-the salivary gland cancer biomarker-with a limit of detection as low as 30 nm.

Particle-shape-, temperature-, and concentration-dependent thermal conductivity and viscosity of nanofluids.

In this study, using the Green-Kubo-method-based molecular dynamics simulations, correlations for predicting the thermophysical properties of nanofluids are developed based on particle shape, fluid temperature, and volume concentration. Silver nanofluids with various nanoparticle shapes including spheres, cubes, cylinders, and rectangular prisms are investigated. The numerical study is conducted within the concentration range 0.

Optimized Synthesis of Poly(deoxyribose) Isobutyrate, a Viscous Biomaterial for Bone Morphogenetic Protein-2 Delivery.

Injectable and phase-transitioning carriers from natural polysaccharides have great potential for the minimally invasive delivery of therapeutic proteins in the field of bone tissue engineering. In this study, a novel and highly viscous drug carrier was synthesized by a sequential process of deoxyribose polycondensation and esterification. The effect of synthesis parameters on the molecular weight, viscosity, and adhesion of the material was studied and correlated to temperature and time of polycondensation ( T and t), time and temperature of esterification ( T and t), and the molar ratio of the monomer ( R).
