biomedical, forensic and environmental sciences 1− 4 as well as in anti bioterrorism …

Nanocrystals are fundamental to modern science and technology. Mastery over the shape of
a nanocrystal enables control of its properties and enhancement of its usefulness for a given …

Nanoscience includes the study of objects and systems in which at least one dimension is 1-
100 nm. The objects studied in this range of sizes are larger than atoms and small …

Although gold is the subject of one of the most ancient themes of investigation in science, its
renaissance now leads to an exponentially increasing number of publications, especially in …

Two-dimensional transition metal dichalcogenides (TMDs), such as MoS2, generally exist in
two different polymorphic structures, metallic (1T phase) and semiconducting (2H phase). In …

Peroxidase mimics with dimensions on the nanoscale have received great interest as
emerging artificial enzymes for biomedicine and environmental protection. While a variety of …

A robust solid sensing platform for an on-site operational and accurate detection of heavy
metal is still a challenge. We introduce chitosan based carbon dots rooted agarose hydrogel …

A variety of metallic nanoparticles with a narrow size distribution have been synthesized in a
facile one-phase method in which amine− borane complexes are applied as reducing …

Gold nanoparticles (AuNPs) have found a wide range of biomedical and environmental
