“…Second, oligoradicals could continue to form new particles via the nucleation process. Due to the fact that these two processes controlled the reaction in each step . At a low initiator concentration, the oligoradicals could grow less into particles with a small change size resulting in the particle size of 44 to 46 nm.…”

Poly(methy methacrylate) (PMMA)-SiO 2 nanoparticles were prepared via differential microemulsion polymerization. The effects of silica loading, surfactant concentration, and initiator concentration on monomer conversion, particle size, particle size distribution, grafting efficiency, and silica encapsulation efficiency were investigated. A high monomer conversion of 99.9% and PMMA-SiO 2 nanoparticles with a size range of 30 to 50 nm were obtained at a low surfactant concentration of 5.34 wt% based on monomer. PMMA-SiO 2 nanoparticles showed spherical particles with a core-shell morphology by TEM micrographs. A nanocomposite membrane from natural rubber (NR) and PMMA-SiO 2 emulsion was studied for mechanical and thermal properties and pervaporation of water-ethanol mixtures. PMMA-SiO 2 nanoparticles which were uniformly dispersed in NR matrix, significantly enhanced mechanical properties and showed high water selectivity in permeate flux. Thus, the NR/PMMA-SiO 2 hybrid membranes have great potential for pervaporation process in membrane applications. POLYM. ENG. SCI.,

“…The particle size increased slightly with an increase in the initiator concentration. This phenomenon can be explained in that increasing the initiator concentration results in more nucleation in the water phase as a result of more free radicals being formed [26]. Thus, some dead polymer occurred from combination of two radicals having carbon double bonds in polymer chains probably have more chance to be initiated to new radicals that could play a role on the polymerization resulting in the larger particle size.…”

“…[441][442][443][444] To produce hydrophobic polymeric NPs, the most commonly used precursors are poly-lactic acid (PLA), 445 poly-lactic-co-glycolic acid (PGLA), 446 or polystyrene (PS), 447 while for hydrophilic NPs the most favored materials are PEG, 448 poly-ethyleneimine (PEI), 449 poly-lysine, 450 and sometimes poly-methyl methacrylate (PMMA) when appropriately modified. 451 Each of them have their respective advantages and disadvantages. For instance, hydrophobic particles are ideal to encapsulate hydrophobic drugs and fluorophores while hydrophilic NPs are more compatible with bodily fluids and can be more easily functionalized with biorecognition or targeting molecules.…”

Functionally integrating DNA and other nucleic acids with nanoparticles in all their different physicochemical forms has produced a rich variety of composite nanomaterials which, in many cases, display unique or augmented properties due to the synergistic activity of both components. These capabilities, in turn, are attracting greater attention from various research communities in search of new nanoscale tools for diverse applications that include (bio)sensing, labeling, targeted imaging, cellular delivery, diagnostics, therapeutics, theranostics, bioelectronics, and biocomputing to name just a few amongst many others. Here, we review this vibrant and growing research area from the perspective of the materials themselves and their unique capabilities. Inorganic nanocrystals such as quantum dots or those made from gold or other (noble) metals along with metal oxides and carbon allotropes are desired as participants in these hybrid materials since they can provide distinctive optical, physical, magnetic, and electrochemical properties. Beyond this, synthetic polymer-based and proteinaceous or viral nanoparticulate materials are also useful in the same role since they can provide a predefined and biocompatible cargo-carrying and targeting capability. The DNA component typically provides sequence-based addressability for probes along with, more recently, unique architectural properties that directly originate from the burgeoning structural DNA field. Additionally, DNA aptamers can also provide specific recognition capabilities against many diverse non-nucleic acid targets across a range of size scales from ions to full protein and cells. In addition to appending DNA to inorganic or polymeric nanoparticles, purely DNA-based nanoparticles have recently surfaced as an excellent assembly platform and have started finding application in areas like sensing, imaging and immunotherapy. We focus on selected and representative nanoparticle-DNA materials and highlight their myriad applications using examples from the literature. Overall, it is clear that this unique functional combination of nanomaterials has far more to offer than what we have seen to date and as new capabilities for each of these materials are developed, so, too, will new applications emerge.
