“…In work by the Wang group, acrylic acid was polymerized from the surfaces of nanoparticles using O-ATRP mediated by PhenS-Ph. While polymerization control was not evaluated in this report, the successful polymerization of this monomer was verified by FT-IR and transmission electron microscopy . In 2021, Qian, Han, Zhang, and co-workers demonstrated the polymerization of hexadecyl acrylate from functionalized cellulose-based fibers, although polymerization control was again not evaluated .…”

“…In addition to these SiO 2 -based materials, a number of other nanoparticles have been modified using surface-initiated O-ATRP. These include ceria nanoparticles, nanodiamond, rare earth doped upconversion nanoparticles, magnetic Fe 3 O 4 nanoparticles, , ferroelectric BaTiO 3 nanoparticles, cellulose nanocrystals, and Eu 3+ doped luminescent hydroxyapatite. − In particular, the functionalization of hydroxyapatite nanorods by O-ATRP has received considerable attention, with target applications including biological imaging and drug delivery. Often, surface functionalization of the nanorods is used to improve their solubility and cell-uptake properties, with the most common monomer being PEG methacrylate (Figure ).…”

The development of photoinduced organocatalyzed atom transfer radical polymerization (O-ATRP) has received considerable attention since its introduction in 2014. Expanding on many of the advantages of traditional ATRP, O-ATRP allows well-defined polymers to be produced under mild reaction conditions using organic photoredox catalysts. As a result, O-ATRP has opened access to a range of sensitive applications where the use of a metal catalyst could be of concern, such as electronics, certain biological applications, and the polymerization of coordinating monomers. However, key limitations of this method remain and necessitate further investigation to continue the development of this field. As such, this review details the achievements made to-date as well as future research directions that will continue to expand the capabilities and application landscape of O-ATRP. CONTENTS 4.5.

“…The corresponding UV–vis absorption spectra of UCNP-OA and UCNP-PAA were almost the same (Figure S3) and upconversion photoluminescent spectrum of OA-capped UCNP and PAA-capped UCNP both possess three Er 3+ distinct emission bands (Figure S4). The green light emission was ascribed to the transitions of 2 H 11/2 – 4 I 15/2 (521 nm), 4 S 3/2 – 4 I 15/2 (539 nm), and red emission were connected with the transitions of 4 F 9/2 – 4 I 15/2 (654 nm) of the Er 3+ ions …”

Transparent upconversion photoluminescent polyamide nanocomposites were fabricated via a facile in situ polycondensation method with interfacial chemistry modification employing polyacrylic acid-functionalized upconversion nanoparticles (UCNP-PAA) as fillers and transparent semiaromatic polyamides (SAPA) as host materials. The as-prepared UCNP-PAA could be dispersed uniformly in the polyamide salt solution and the SAPA chains can be grafted to the UCNP-PAA through condensation reactions. The grafted SAPA ligand on the surface of UCNP increases the compatibility between SAPA and UCNP, thus causing uniform dispersion of the UCNP in the polyamide nanocomposites and improving the transmittance of the polyamide nanocomposites. The obtained polyamide nanocomposites are transparent and show strong green upconversion photoluminescence. This work solved the problem of the dispersity of incorporated nanoparticles and improving the transparency of nanocomposites and, more importantly, endowed the traditional engineering plastic with upconversion photoluminescent properties which can be applied in three-dimensional displays and the related solar cell field in the future.

“…Процедура подразумевает обмен между исходными лигандами (например, олеиновой кислотой), находящимися на поверхности наночастицы, и бифункциональными органическими молекулами или полимерами. К настоящему времени известны технологии, позволяющие модифицировать поверхность наночастиц следующими соединениями: полиэтиленгликоли, полиакриловая кислота, 3-меркаптопропионовая кислота, адипиновая кислота, 2-аминоэтилдигидрофосфат [122][123][124][125][126][127][128]. Следует отметить, что такой метод модификации поверхности наночастиц может приводит к снижению интенсивности люминесценции РЗИ за счет гашения свечения высокочастотными колебательными группами (−OH и −NH 2 ), введенными во время процедуры обмена [118].…”

Luminescent nanomaterials doped with rare-earth elements are characterized by such physicochemical properties as long-lived luminescence, large Stokes or anti-Stokes shifts, narrow emission bands, high photostability and low toxicity. These materials can be considered as a new generation of biosensors along with conventional molecular probes, such as organic dyes, quantum dots and chelate-based lanthanide probes. In recent years there has been significant interest in the study of functional nanomaterials based on rare earth elements. The purpose of this paper is to provide an overview of recent advances in the development of luminescent inorganic nanoparticles doped with rare earth elements which could be used for biomedical applications.
