Abstract
There are several requirements for the safe and effective delivery of therapeutic agents for human use. Direct injection of drugs may cause side effects due to their permeation to other, undiseased regions of the body so that concealment and targeting with appropriate materials is a critical consideration in the design of practical drug delivery systems. In particular, carriers with structures which can be flexibly controlled are more useful since functional structure units can be assembled in component-by-component and/or layer-by-layer fashion. In this review, we focus on preparation of layer-by-layer shells directed at drug delivery applications. After a description of the fundamentals of layer-by-layer (LbL) assembly, recent progress in the field of self-assembled microshells and nanoshells for drug delivery applications are summarized. In addition, concepts developed to solve current difficulties are also described. Encapsulation of insoluble drugs in nanoshells and their delivery can satisfy some of the demands of practical medical use. Thus, aqueous suspensions of insoluble drugs have been subjected to powerful ultrasonic treatment followed by sequential addition of polycations and polyanions to the particle solution leading to assembly of ultra-thin polyelectrolyte shells on the nano-sized drug particles. In another innovative example, stepwise release of drugs from LbL films of mesoporous capsules to the exterior in the absence of external stimuli was demonstrated. It can be regarded as stimuli-free auto-modulated material release.

Abstract
Nano-encapsulation of a poorly soluble anticancer drug was demonstrated with a sonication assisted layer-by-layer polyelectrolyte coating (SLbL). We changed the strategy of LbL-encapsulation from making microcapsules with many layers in the walls for encasing highly soluble materials to using a very thin polycation/polyanion coating on low solubility nanoparticles to provide them with good colloidal stability. SLbL encapsulation of paclitaxel resulted in stable 100-200 nm diameter colloids with a high electrical surface ξ-potential (of -45 mV) and drug content in the nanoparticles of 90 wt%. In the top-down approach, nanocolloids were prepared by rupturing a powder of paclitaxel using ultrasonication and simultaneous sequential adsorption of oppositely charged biocompatible polyelectrolytes. In the bottom-up approach paclitaxel was dissolved in organic solvent (ethanol or acetone), and drug nucleation was initiated by the addition of aqueous polyelectrolyte assisted by ultrasonication. Paclitaxel release rates from such nanocapsules were controlled by assembling multilayer shells with variable thicknesses and were in the range of 10-20 h.

Abstract
Aptamer-polyelectrolyte microcapsules are prepared for potential use as triggered delivery vehicles and microreactors. The hollow microcapsules are prepared from the sulforhodamine B aptamer and the polyelectrolytes poly(allylamine hydrochloride) and poly(sodium 4-styrene-sulfonate), using layer-by-layer (LbL) film deposition templated on a sacrificial CaCO(3) spherical core. Scanning electron microscopy and confocal microscopy confirm the formation of spherical CaCO(3) cores and LbL-aptamer microcapsules. Colocalization studies with fluorescently-tagged aptamer and sulforhodamine B verify the ability of the aptamer to recognize its cognate target in the presence of the K(+) ions that are required for its characteristic G-quadruplex formation. Fluorescence recovery after photobleaching studies confirms a significant difference in the permeability of the aptamer-polyelectrolyte microcapsules for the sulforhodamine B dye target compared to control microcapsules prepared with a random oligonucleotide. These results suggest that aptamer-based 'smart' responsive films and microcapsules could be applied to problems of catalysis and controlled release.

Abstract
Inspired by the game of "pinball" where rolling metal balls are guided by obstacles, here we describe a novel microfluidic technique which utilizes micropillars in a flow channel to continuously generate, encapsulate and guide Layer-by-Layer (LbL) polyelectrolyte microcapsules. Droplet-based microfluidic techniques were exploited to generate oil droplets which were smoothly guided along a row of micropillars to repeatedly travel through three parallel laminar streams consisting of two polymers and a washing solution. Devices were prototyped in PDMS and generated highly monodisperse and stable 45±2 µm sized polyelectrolyte microcapsules. A total of six layers of hydrogen bonded polyelectrolytes (3 bi-layers) were adsorbed on each droplet within <3 minutes and a fluorescent intensity measurement confirmed polymer film deposition. AFM analysis revealed the thickness of each polymer layer to be approx. 2.8 nm. Our design approach not only provides a faster and more efficient alternative to conventional LbL deposition techniques, but also achieves the highest number of polyelectrolyte multilayers (PEMs) reported thus far using microfluidics. Additionally, with our design, a larger number of PEMs can be deposited without adding any extra operational or interfacial complexities (e.g. syringe pumps) which are a necessity in most other designs. Based on the aforementioned advantages of our device, it may be developed into a great tool for drug encapsulation, or to create capsules for biosensing where deposition of thin nanofilms with controlled interfacial properties is highly required.

Abstract
Aqueous nanocolloids of poorly soluble materials were produced via sonicated layer-by-layer (LbL) encapsulation with polycation / polyanion shells. Synergy of simultaneous breaking powder particles with ultrasonication and coating them with polycations allowed for the production of 150-200 nm diameter polyelectrolyte coated nanoparticles with sufficient surface electrical potential for colloidal stability. This technique increases water dispersibility of low soluble materials ranging from anticancer drugs to anticorrosion agents, dyes and inorganic salts.

Abstract
Multilayered polymer capsules attract significant research attention and are proposed as candidate materials for diverse biomedical applications, from targeted drug delivery to microencapsulated catalysis and sensors. Despite tremendous efforts, the studies which extend beyond proof of concept and report on the use of polymer capsules in drug delivery are few, as are the developments in encapsulated catalysis with the use of these carriers. In this Concept article, the recent successes of poly(methacrylic acid) hydrogel capsules as carrier vessels for delivery of therapeutic cargo, creation of microreactors, and assembly of sub-compartmentalized cell mimics are discussed. The developed technologies are outlined, successful applications of these capsules are highlighted, capsules properties which contribute to their performance in diverse applications are discussed, and further directions and plausible developments in the field are suggested.

Abstract
We propose dextran and dextran polyaldehyde (DPA) coatings for modification of layer-by-layer (LbL) assembled polyelectrolyte microcapsules which provide stability against aggregation in 0.75 M aqueous solutions of mono- and bivalent ions (Na(+), Cl(-), Ca(2+), HPO(4)(2-)). The microcapsules were prepared of three bilayers of poly(4-styrenesulfonate) (PSS) and poly(allylamine) (PAH). Dextran and its derivatives were attached to amino-terminated surface of the microcapsules via three types of chemical bonds of subsequently increasing strength: (1) hydrogen bonds, (2) hydrolyzable covalent cross-links resulting from aldehydes and primary amines coupling, and (3) nonhydrolyzable covalent C-N single bonds of secondary amines. Attachment of the DPA materials via the latter two types of bonds resulted in strengthening the capsules' walls which preserved a fraction of the microcapsules from disintegration upon electrostatic swelling in 0.1 M NaOH. The non-disintegrated fraction of the DPA-coated microcapsules restored their initial size after pH was decreased back to neutral. The microcapsules coated with the original dextran immobilized via hydrogen bonds and the bare microcapsules were fully dissolved under the alkaline conditions. The preserved fraction of the microcapsules was higher for the DPA materials with higher contents of the aldehyde groups and after conversion of the hydrolyzable covalent cross-links to the nonhydrolyzable secondary amines via reduction with NaBH(4). The higher contents of the aldehyde groups and the reduction led to the lower limiting swelling degree of the DPA-coated microcapsules at alkaline pH. The proposed coatings can be used for colloid stabilization of polyelectrolyte microcapsules in aqueous medium, encapsulation of pH-insensitive macromolecules at the postpreparation stage, and pH-triggered release of encapsulated material.

Abstract
Multilayers formed by the sodium salt of poly(4-styrenesulfonate), PSS, and triblock copolymers of the form PDMAEMA-PCL-PDMAEMA (PDMAEMA corresponding to poly[2-(N,N-dimethylamino)ethyl methacrylate), and PCL to poly(epsilon-caprolactone) have been built by layer-by-layer self-assembly from the aqueous polyelectrolyte solutions. Two types of block copolymers have been used which differ on the type of the amino groups, either hydrochloride or quaternized. This leads to changes in the charge density of the chains for the same content of amino groups. The growth of the multilayers has been followed using dissipative quartz crystal microbalance and ellipsometry techniques. The results show that, independently of the conditions used in the assembling, the film thickness grows linearly with the number of layers. The comparison of the thickness values obtained from D-QCM and ellipsometry has allowed us to calculate the water content of the polymer film. The analysis of the D-QCM data also provides the shear modulus, whose values are typical of a rubber-like polymer system. The analysis of the mass adsorbed calculated by the ellipsometric measurements indicated that the nature of the charge compensation mechanism is extrinsic for all the studied systems, although the degree of extrinsic compensation is strongly dependent on the copolymer used and the concentration in solution. Finally, it was found that the adsorption kinetic of the layers is bimodal for all the films built. Even though the characteristic adsorption times depend on the specific copolymer used, no dependence on the number of layers has been found for a given multilayer.

Abstract
A new method of nanoparticle formulation for poorly water-soluble materials was demonstrated for curcumin. The drug was dissolved in organic solvent that is miscible with water (ethanol), and drug nucleation was initiated by gradual worsening of the solution by the addition of an aqueous polyelectrolyte assisted by ultrasonication. Curcumin crystals of 60-100 nm size were obtained depending on the component concentrations, sonication power, and initial solvent. Layer-by-layer shell assembly with biocompatible polyelectrolytes was used to provide a particle coating with a high surface potential and the stabilization of drug nanocolloids. Polyelectrolyte layer-by-layer encapsulation allowed sustained drug release from nanoparticles over the range of 10-20 h.

Abstract
Aim: The lack of sensitivity of chronic myeloid leukemia (CML) stem cells to imatinib mesylate (IM) commonly leads to drug dose escalation or early disease relapses when therapy is stopped. Here, we report that packaging of IM into a biodegradable carrier based on polyelectrolyte microcapsules increases drug retention and antitumor activity in CML stem cells, also improving the ex vivo purging of malignant progenitors from patient autografts. Materials & methods: Microparticles/capsules were obtained by layer-by-layer (LbL) self-assembly of oppositely charged polyelectrolyte multilayers on removable calcium carbonate (CaCO3) templates and loaded with or without IM. A leukemic cell line (KU812) and CD34+ cells freshly isolated from healthy donors or CML patients were tested. Results & discussion: Polyelectrolyte microcapsules (PMCs) with an average diameter of 3 µm, fluorescently labelled multilayers sensitive to the action of intracellular proteases and 95–99% encapsulation efficiency of IM, were prepared. Cell uptake efficiency of such biodegradable carriers was quantified in KU812, leukemic and normal CD34+ stem cells (range: 70–85%), and empty PMCs did not impact cell viability. IM-loaded PMCs selectively targeted CML cells, by promoting apoptosis at doses that exert only cytostatic effects by IM alone. More importantly, residual CML cells from patient leukapheresis products were reduced or eliminated more efficiently by using IM-loaded PMCs compared with freely soluble IM, with a purging efficiency of several logs. No adverse effects on normal CD34+ stem-cell survival and their clonogenic potential was noticed in long-term cultures of hematopoietic progenitors in vitro. Conclusion: This pilot study provides the proof-of-principle for the clinical application of biodegradable IM-loaded PMC as feasible, safe and effective ex vivo purging agents to target CML stem cells, in order to improve transplant outcome of resistant/relapsed patients or reduce IM dose escalation.

Abstract
Nanomagnetic particles have been already taken into account as drug carriers thank to the possibility to control their movement to a specific location where the treatment is required by means of high gradient magnetic fields (HGMF). In this work the layer-by-layer technique (LbL) and nanomagnetic particles were used to developed innovative nanostructured magnetic capsules (NSMC). Their potential application as magnetic drug carriers was investigated under the influence of both static and oscillating magnetic fields used respectively to control capsule displacement and shell permeability. The assembly process of the nanostructured magnetic capsules, its characterization by Quartz Crystal Microbalance (QCM), and the results obtained under the influence of the magnetic fields are presented.
