Abstract
Since the discovery of polymerization-induced self-assembly (PISA), convenient synthesis of concentrated block copolymer nano-assemblies dispersed in solvent has been achieved. Now, application of block copolymer nano-assemblies should be paid more attention. In this study, corona-cross-linked block copolymer nanoparticles of poly[dimethylacrylamide-co-(diacetone acrylamide)]-b-polystyrene [P(DMA-co-DAAM)-b-PS] containing the poly(DAAM) segment in the hydrophilic P(DMA-co-DAAM) block are synthesized initially by PISA following dispersion RAFT polymerization and then by covalent intraparticle cross-linking through the poly(DAAM) segment and adipic acid dihydrazide (ADH). Coating application of the corona-cross-linked block copolymer nano-assemblies is tried, and much higher water resistance of the corona-cross-linked block copolymer nano-assemblies than that of the linear block copolymer nano-assemblies is demonstrated.

Abstract
Soft nanoparticles continue to offer a promising platform for the encapsulation and controlled delivery of poorly water-soluble drugs and help enhance their bioavailability at targeted sites. Linear amphiphilic block copolymers are the most extensively investigated in formulating delivery vehicles. However, more recently, there has been increasing interest in utilizing branched macromolecules for nanomedicine, as these have been shown to lower critical micelle concentrations, form particles of smaller dimensions, facilitate the inclusion of varied compositions and function-based entities, as well as provide prolonged and sustained release of cargo. In this review, it is aimed to discuss some of the key variables that are studied in tailoring branched architecture-based assemblies, and their influence on drug loading and delivery. By understanding structure-property relationships in these formulations, one can better design branched star polymers with suitable characteristics for efficient therapeutic interventions. The role played by polymer composition, chain architecture, crosslinking, stereocomplexation, compatibility between polymers and drugs, drug/polymer concentrations, and self-assembly methods in their performance as nanocarriers is highlighted.

Abstract
Delivering active pharmaceutical agents to disease sites using soft polymeric nanoparticles continues to be a topical area of research. It is becoming increasingly evident that the composition of amphiphilic macromolecules plays a significant role in developing efficient nanoformulations. Branched architectures with asymmetric polymeric arms emanating from a central core junction have provided a pivotal venue to tailor their key parameters. The build-up of miktoarm stars offers vast polymer arm tunability, aiding in the development of macromolecules with adjustable properties, and allows facile inclusion of endogenous stimulus-responsive entities. Miktoarm star-based micelles have been demonstrated to exhibit denser coronae, very low critical micelle concentrations, high drug loading contents, and sustained drug release profiles. With significant advances in chemical methodologies, synthetic articulation of miktoarm polymer architecture, and determination of their structure-property relationships, are now becoming streamlined. This is helping advance their implementation into formulating efficient therapeutic interventions. This review brings into focus the important discoveries in the syntheses of miktoarm stars of varied compositions, their aqueous self-assembly, and contributions their formulations are making in advancing the field of drug delivery.

Abstract
Intracellular temperature plays a prominent role in cellular functions and biochemical activities inside living cells, but effective intracellular temperature sensing and imaging is still in its infancy. Herein, thermoresponsive double hydrophilic block copolymers (DHBCs)-based fluorescent thermometers were fabricated to investigate their application in intracellular temperature imaging. Blue-emitting coumarin monomer, CMA, green-emitting 7-nitro-2,1,3-benzoxadiazole (NBD) monomer, NBDAE, and red-emitting rhodamine B monomer, RhBEA, were copolymerized separately with N-isopropylacrylamide (NIPAM) to afford dye-labeled PEG-b-P(NIPAM-co-CMA), PEG-b-P(NIPAM-co-NBDAE), and PEG-b-P(NIPAM-co-RhBEA). Because of the favorable fluorescence resonance energy transfer (FRET) potentials between CMA and NBDAE, NBDAE and RhBEA, as well as the slight tendency between CMA and RhBEA fluorophore pairs, three polymeric thermometers based on traditional one-step FRET were fabricated by facile mixing two of these three fluorescent DHBCs, whereas exhibiting limited advantages. Thus, two-step cascade FRET among three polymeric fluorophores was further interrogated, in which NBD acted as a bridging dye by transferring energy from CMA to RhBEA. Through the delicate optimization of the molar contents of three polymeric components, a ∼8.4-fold ratio change occurred in the temperature range of 20-44 °C, and the detection sensitivity improved significantly, reached as low as ∼0.4 °C, which definitely outperformed other one-step FRET thermometers in the intracellular temperature imaging of living cells. To our knowledge, this work represents the first example of polymeric ratiometric thermometer employing thermoresponsive polymer-based cascade FRET mechanism.

Abstract
A novel nanocontainer, which has silica nanotube (SNT) core and pH-sensitive polymer shell attaching on the exterior surface of silica nanotube, is presented in this paper. Polymer nanorods, which are conveniently fabricated though polymerization-induced self-assembly and reorganization method, are used as templates for the deposition of silica to fabricate hybrid nanorods. Calcination of as-synthesized silica hybrid nanorods leads to hollow SNTs. SNTs are functionalized with reversible addition-fragmentation chain transfer (RAFT) agent, then surface RAFT polymerization is conducted to get poly(2-(diethylamino)ethyl methacrylate)-b-poly(oligo(ethylene glycol) methacrylate)-coated SNTs (SNT-PDEAEMA-b-POEGMA). Doxorubicin (DOX) can be encapsulated in SNT-PDEAEMA-b-POEGMA, and controlled release of loaded DOX is achieved by adjusting pH of the medium. In vitro cell viability and cellular internalization study confirm the potential application of this nanocontainer in drug and gene delivery.

Abstract
Cancer remains a major killer and a leading cause of death in the world; thus, a growing number of new treatments have been focused on cancer therapy over the past few decades. Chemotherapy, which is thought to be a powerful strategy for cancer treatment, has been widely used in clinical therapy in recent years. However, due to the complexity of cancer, a single therapeutic approach is insufficient for the suppression of cancer growth and migration. Therefore, increasing attention has been paid to the use of smart multifunctional carriers and combinatorially delivers chemotherapeutic drugs and functional genes in order to maximize therapeutic efficiency. Combination therapy using selected drugs and genes can not only overcome multidrug resistance and inhibit the cellular anti-apoptotic process but also achieve a synergistic therapeutic effect. Because multifunctional nanocarriers are important for achieving these goals, this review will illustrate and discuss some advanced biomaterial nanocarriers for co-delivering therapeutic genes and drugs, including multifunctional micelles, liposomes, polymeric conjugates and inorganic nanoparticles. In addition, the challenges and future perspectives for co-delivery systems, containing therapeutic drugs and genes to achieve better therapeutic effects for cancer treatment will be discussed.

Abstract
Two series of copolymers were prepared by ring-opening polymerization (ROP) of γ-(2-methoxyethoxy)esteryl-L-glutamate (L-EG2Glu) N-carboxyanhydride (NCA) and L-alanine (L-Ala) using HMDS and PEG-NH2 as initiator, respectively. Poly-(L-EG2Glu-co-L-Ala) displayed lower critical solution temperature (LCST) behavior but had a lower phase transition temperature than poly-L-EG2Glu at similar molecular weight (MW). The clouding point (CP) of random copolypeptides can be tuned by altering the alanine content and overall MW. Circular dichroism (CD) and Fourier transform infrared spectroscopy (FTIR) indicated that the thermal-responsive properties depended on the content of ordered conformations. PEG-b-poly-(L-EG2Glu-co-L-Ala) can spontaneously form hydrogels in water at room temperature. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) revealed that these hydrogels were formed by nanoribbons. The intermolecular hydrogen bonding among copolypeptide blocks accounted for the nanoribbon assemblies and hydrogel network formation.

Abstract
PLGA porous microspheres loaded with doxorubicin (DOX) and paclitaxel (PTX) were developed for in situ treatment of metastatic lung cancer. The synergistic effect of the combined drugs was investigated against B16F10 cells to obtain the optimal prescription for in vivo studies. The combination therapy showed great synergism when DOX was the majority in the combination therapy, while they showed moderate antagonism when PTX is in major. The combination of DOX and PTX at a molar ratio of 5/1 showed the best synergistic therapeutic effect in the free form. However, the drugs exhibited more synergism in the PLGA microspheres at a molar ratio of 2/1, due to the difference in drug release rate. The in vivo study verified the synergism of DOX and PTX at the optimal molar ratio. These results suggested that dual encapsulation of DOX and PTX in porous PLGA microspheres would be a promising technology for long effective lung cancer treatment.

Abstract
A novel methoxy poly(ethylene glycol)-b-poly(l-glutamic acid)-b-poly(l-phenylalanine) (mPEG-b-P(Glu)-b-P(Phe)) triblock copolymer was prepared and explored as a micelle carrier for the co-delivery of paclitaxel (PTX) and cisplatin (cis-diamminedichlo-platinum, CDDP). PTX and CDDP were loaded inside the hydrophobic P(Phe) inner core and chelated to the middle P(Glu) shell, respectively, while mPEG provided the outer corona for prolonged circulation. An in vitro release profile of the PTX+CDDP-loaded micelles showed that the CDDP chelation cross-link prevented an initial burst release of PTX. The PTX+CDDP-loaded micelles exhibited a high synergism effect in the inhibition of A549 human lung cancer cell line proliferation over 72 h incubation. For the in vivo treatment of xenograft human lung tumor, the PTX+CDDP-loaded micelles displayed an obvious tumor inhibiting effect with a 83.1% tumor suppression rate (TSR%), which was significantly higher than that of a free drug combination or micelles with a single drug. In addition, more importantly, the enhanced anti-tumor efficacy of the PTX+CDDP-loaded micelles came with reduced side-effects. No obvious body weight loss occurred during the treatment of A549 tumor-bearing mice with the PTX+CDDP-loaded micelles. Thus, the polypeptide-based combination of PTX and CDDP may provide useful guidance for effective and safe cancer chemotherapy.
