Abstract
Zeolites have attractive features making them suitable carriers for drug delivery systems (DDS). As such, we loaded the anticancer drug 5-fluorouracil (5-FU), into two different zeolite structures, faujasite (NaY) and Linde Type L (LTL), to obtain different DDS. The prepared DDS were tested in vitro using breast cancer, colorectal carcinoma, and melanoma cell lines and in vivo using the chick embryo chorioallantoic membrane model (CAM). Both assays showed the best results for the Hs578T breast cancer cells, with a higher potentiation for 5-FU encapsulated in the zeolite LTL. To unveil the endocytic mechanisms involved in the internalization of the zeolite nanoparticles, endocytosis was inhibited pharmacologically in breast cancer and epithelial mammary human cells. The results suggest that a caveolin-mediated process was responsible for the internalized zeolite nanoparticles. Aiming to boost the DDS efficacy, the disc-shaped zeolite LTL outer surface was functionalized using amino (NH2) or carboxylic acid (COOH) groups and coated with poly-l-lysine (PLL). Positively functionalized surface LTL nanoparticles revealed to be non-toxic to human cells and, importantly, their internalization was faster and led to a higher tumor reduction in vivo. Overall, our results provide further insights into the mechanisms of interaction between zeolite-based DDS and cancer cells, and pave the way for future studies aiming to improve DDS anticancer activity.

Abstract
The biomimetic anisotropic particles have different physicochemical properties on the opposite two sides, enabling diverse applications in emulsion, photonic display, and diagnosis. However, the traditional anisotropic particles have a very small size, ranging from submicrons to a few microns. The design and fabrication of anisotropic macron-sized particles with new structures and properties is still challenging. In this study, anisotropic polycaprolactone (PCL) microparticles well separated with each other were prepared by crystallization from the dilute PCL solution in a porous 3D gelatin template. They had fuzzy and smooth surfaces on each side, and a size as large as 70 μm. The fuzzy surface of the particle adsorbed significantly larger amount of proteins, and was more cell-attractive regardless of the cell types. The particles showed stronger affinity toward fibroblasts over hepatocytes, which paved a new way for cell isolation merely based on the surface morphology. After a successive seeding process, Janus cell microparticles with fibroblasts and endothelial cells (ECs) on each side were designed and obtained by making use of the anisotropic surface morphology, which showed significant difference in EC functions in terms of prostacyclin (PGl2) secretion, demonstrating the unique and appealing functions of this type of anisotropic microspheres.

Abstract
Empty spaces are abhorred by nature, which immediately rushes in to fill the void. Humans have learnt pretty well how to make ordered empty nanocontainers, and to get useful products out of them. When such an order is imparted to molecules, new properties may appear, often yielding advanced applications. This review illustrates how the organized void space inherently present in various materials: zeolites, clathrates, mesoporous silica/organosilica, and metal organic frameworks (MOF), for example, can be exploited to create confined, organized, and self-assembled supramolecular structures of low dimensionality. Features of the confining matrices relevant to organization are presented with special focus on molecular-level aspects. Selected examples of confined supramolecular assemblies - from small molecules to quantum dots or luminescent species - are aimed to show the complexity and potential of this approach. Natural confinement (minerals) and hyperconfinement (high pressure) provide further opportunities to understand and master the atomistic-level interactions governing supramolecular organization under nanospace restrictions.

Abstract
Zeolites are crystalline porous materials with a regular framework which have non-toxic effects on a variety of human cell lines and have been explored for cell imaging and drug delivery. Understanding the interaction between zeolite nanoparticles and cells is imperative for improving their potentialities, since the process of internalization of these particles is still poorly understood. In this study, the intracellular trafficking and internalization kinetics of zeolite L into breast cancer cells and normal epithelial mammary cells were analysed using scanning electron microscopy (SEM), confocal microscopy and transmission electron microscopy (TEM). We also studied the involvement of endocytic pathways using two pharmacological inhibitors, chlorpromazine and dynasore. Zeolite nanoparticles were taken up by both cell types and the cellular uptake was fast, and started immediately after 5 min of incubation. Interestingly, the uptake was dependent on the cell type since in breast cancer cells it was faster and more efficient, with a higher number of nanoparticles being internalized by cancer cells over time, compared to that in the epithelial mammary cells. TEM results showed that the internalized nanoparticles were mainly localized in the cell vacuoles. The data obtained upon using endocytic pharmacological inhibitors suggest that the zeolite L uptake is mediated by caveolin.

Abstract
Recently, there has been much interest in the chirality-dependent cell affinity to enantiomorphous nanomaterials (NMs), since, at the nanoscale level, enantiomers of (bio)molecules have different effects on cell behaviors. In this respect, this study used enantiomorphous NMs with which to generate the Janus nanocomposite (NC) hydrogels as multifunctional biomaterials for studying chirality-dependent cell adhesion and cell migration. These Janus NC hydrogels possess two enantiomorphous NC hydrogels, in which the different halves of the hydrogel contain the opposite enantiomers of a biopolymer functionalized nanomaterials. Thus, the enantiomers contact each other only at the midline of the hydrogel but are otherwise separated, yet they are present in the same system. This advanced system allows us to simultaneously study the impact that each enantiomer of a biopolymer has on cell behavior under the same reaction conditions, at the same time, and using only a single biomaterial. Our results show that cells have higher affinity for and migrate toward the part of the Janus NC hydrogel containing the biopolymer enantiomer that the cells prefer.

Abstract
Porous materials with molecular-sized periodic structures, as exemplified by zeolites, metal-organic frameworks, or mesoporous silica, have attracted increasing attention due to their range of applications in storage, sensing, separation, and transformation of small molecules. Although the components of such porous materials have a tendency to pack in unidirectionally oriented periodic structures, such ideal types of packing cannot continue indefinitely, generally ceasing when they reach a micrometer scale. Consequently, most porous materials are composed of multiple randomly oriented domains, and overall behave as isotropic materials from a macroscopic viewpoint. However, if their channels could be unidirectionally oriented over a macroscopic scale, the resultant porous materials might serve as powerful tools for manipulating molecules. Guest molecules captured in macroscopically oriented channels would have their positions and directions well-defined, so that molecular events in the channels would proceed in a highly controlled manner. To realize such an ideal situation, numerous efforts have been made to develop various porous materials with macroscopically oriented channels. An overview of recent studies on the synthesis, properties, and applications of macroscopically oriented porous materials is presented.
