“…The first study on polyacetylene began approximately one half century ago, and so far series of exciting achievements have been 40 made in fundamental research; [19][20][21][22][23][24][25][26][27][28][29][30][31][32] however the progress in practical applications of polyacetylenes is far from being satisfying. The major reason for this terrible situation is attributed to the limitations of polyacetylene and a considerable part of the derivatives, i.e.…”

How to prepare polymeric particles from acetylene and its derivatives, in particular in aqueous media, has remained as a challenging research topic for a rather long period. In recent years, this research area has achieved exciting progress and a variety of novel functional particles have been reported. However, there has not yet a review article exclusively summarizing the progress. This article presents an overview on the advanced particles with emphasis on the preparation and their applications. The state-of-the-art preparation methods fall into two major groups: emulsion, precipitation, suspension polymerization approaches by starting from monomers; and post-treatment of 10 pre-formed polymers (i.e. self-assembly). The polymer particles were investigated in such applications as circuits, sensors, drug release and chiral-related processes for instance asymmetric catalysis, enantioselective crystallization, enantioselective release, amongst many others. The review article is expected to stimulate more unprecedented functional particles derived from acetylene and its derivatives.

presence of an analyte is fi rst detected by interaction with a receptor and is then followed by the transduction of this binding event into a measurable signal. [ 2 ] Selectivity and sensitivity are the most important requirements of a sensor. The selectivity of a chemical sensor is very dependent on its receptor. To attain high selectivity, specifi c interaction between the receptor and an analyte should exist. [ 3 ] Polymers used for chemical sensing applications can be classifi ed into two categories: polymers interacting with analyte molecules in a receptor and those functioning in a transducer with generating signals. Molecularly imprinted polymers (MIPs) are an interesting class of polymers designed as artifi cial receptors. Conjugated polymers (CPs) are typical Polymers are widely used for chemical sensing applications, as a receptor or as a signal transducer. Fluorescent conjugated polymers (CPs) are extensively studied for signaling. Water-soluble CPs are particularly attractive due to their potential sensing applications in environmental and biorelated fi elds. The CPs by themselves do not provide specifi c binding sites by folding into secondary or tertiary structures. Molecularly imprinted polymers (MIPs) are artifi cial receptors fabricated using the molecular-imprinting technique. They contain in-built information about the shape and functionality of specifi c potential analytes. However, most MIPs do not have optical-signaling properties. In this article, the recent developments regarding luminescent polymeric sensors are briefl y summarized. It will be of great interest if the optical-signal properties of CPs and the selectivity of MIPs are integrated in an advanced polymeric sensor.

“…17 Passing few decades' exploration by scientists, some modification strategies have emerged, mainly including covalent and non-covalent modification methods. [18][19][20][21][22][23] However, most of the existed strategies are still have some 55 drawbacks for surface modification of CNTs. For example, the covalent modification method is based on the surface oxidation of CNTs using strong oxidizing agents.…”

Mussel-inspired PEGylated carbon nanotubes: biocompatibility evaluation and drug delivery applications

Carbon nanotubes (CNTs) have been widely examined for biomedical applications. However, surface functionalization of CNTs with polymers is often required to improve their application performance. To obtain these CNT-based polymer nanocomposites, surface-initiated polymerization strategies are generally adopted. However, all of these methods rely on the surface oxidation of CNTs, which is a rather complex and time-consuming procedure, and involves hazardous reagents. In this work, a facile and efficient bio-inspired strategy was developed for surface PEGylation of CNTs a combination of mussel-inspired chemistry and the Michael addition reaction. The potential biomedical applications of these PEGylated CNTs were evaluated for intracellular delivery of a normally used anticancer drug (Doxorubicin hydrochloride). Two steps were involved in this strategy, which included the surface coating of CNTs with polydopamine (PDA) through self-polymerization of dopamine, and a Michael addition reaction between thePDA-coated CNTs (CNT-PDA) and amino-functionalized polymers, which were obtained by free radical polymerization using poly(ethylene glycol) methyl methacrylate and -(3-aminopropyl) methacrylamide as monomers. Results suggested that these PEGylated CNTs are well dispersed in aqueous solution and showed improved biocompatibility toward cancer cells. On the other hand, we also demonstrated that DOX can be effectively loaded on these PEGylated CNTs and delivered into cells for cancer treatment. More importantly, this strategy can also be utilized for surface modification of many other materials with different polymers due to the strong and universal adhesion of PDA and designability of polymerization. Therefore, this method should be of great interest for the fabrication of multifunctional nanocomposites for biomedical applications.
