“…Furthermore, the silica layer confers protection to the QDs surface and avoids any change by surrounding molecules, such as cations, anions or biomolecules that could affect their emission properties. 28 The InP/ZnS@silica nanospheres (Fig. 1A) have been synthesized using previously reported methods.…”

In this work we describe the synthesis and characterization of InP/ZnS@silica@LDH nanoparticles and, moreover, their use as biomarkers. The use of dual systems combining silica shells and hydrotalcite nanocoatings favors the cell viability in clear contrast with the system with only silica shells. Furthermore, the use of Cd-free luminophores extends the cells lifetime and illustrates the potential of the InP/ZnS@silica@LDH material as biomarker.

“…This state ment has been confirmed by various studies devoted to their practical application. It is natural that safe InP QDs are primarily of interest for biomedical applica tions, such as early in vivo diagnostics of increased production of pancreas cancer cells [1], multispectral luminescent analysis of organs and tissues [70], cell visualization [71,72], drug delivery [73], detection of adenosine triphosphate [74], etc. Semiconductor lasers [75] and materials for solar cells [76] are being developed based on these QDs.…”

Semiconductor colloidal quantum dots possessing unique spectral luminescent characteristics are of great interest for the development of novel materials and devices, which are promising to be used in var ious fields. However, the contemporary high quality quantum dots contain Cd, Pb, Hg, Se, and Te ions and are toxic, with this circumstance limiting their wide practical application. Therefore, the attention of researchers has recently been focused on A III B V semiconductor quantum dots-in particular, InP ones, which are markedly more environmentally safe. InP quantum dots have spectral characteristics similar to those of well studied CdSe quantum dots and can, in principle, replace the latter in many cases, especially, taking into account their more pronounced size effect caused by the narrow energy gap and the large Bohr radius of the exciton. Moreover, the stronger InP covalent bond than the ionic one in A II B VI semiconductors makes it possible to expect that they have a higher photostability and stability in active media. This work pre sents a review of the modern literature devoted to the synthesis and properties of colloidal indium phosphide quantum dots, which are very promising for use as substitutes of toxic cadmium based quantum dots.

“…21,23,24 This is due to the lower mobility of indium compared to Cd ions that can be released from the core despite a shell. The InP/ZnS system as an addressable optical probe was successfully employed for labeling pancreatic cancer cells, 25 fluorescently detecting adenosine triphosphoric acid, 26 and monitoring food freshness. 27 Thus, these biocompatible and environmentally safe core/shell QDs can be unlimitedly utilized in any application.…”
