Abstract
The development of biotechnological protocols based on cationic surfactants is a modern trend focusing on the fabrication of antimicrobial and bioimaging agents, supramolecular catalysts, stabilizers of nanoparticles, and especially drug and gene nanocarriers. The main emphasis given to the design of novel ecologically friendly and biocompatible cationic surfactants makes it possible to avoid the drawbacks of nanoformulations preventing their entry to clinical trials. To solve the problem of toxicity various ways are proposed, including the use of mixed composition with nontoxic nonionic surfactants and/or hydrotropic agents, design of amphiphilic compounds bearing natural or cleavable fragments. Essential advantages of cationic surfactants are the structural diversity of their head groups allowing of chemical modification and introduction of desirable moiety to answer the green chemistry criteria. The latter can be exemplified by the design of novel families of ecological friendly cleavable surfactants, with improved biodegradability, amphiphiles with natural fragments, and geminis with low aggregation threshold. Importantly, the development of amphiphilic nanocarriers for drug delivery allows understanding the correlation between the chemical structure of surfactants, their aggregation behavior, and their functional activity. This review focuses on several aspects related to the synthesis of innovative cationic surfactants and their broad biological applications including antimicrobial activity, solubilization of hydrophobic drugs, complexation with DNA, and catalytic effect toward important biochemical reaction.

Abstract
A promising approach to achieve a more efficient antitumor therapy is the conjugation of the active molecule to a nanostructured delivery system. Therefore, the main objective of this research was to prepare nanoparticles (NPs), with the polymer poly (ε-caprolactone) (PCL), as a carrier for the antitumor drug methotrexate (MTX). A pH-responsive behavior was obtained through conjugation of the amino acid-based amphiphile, 77KL, to the NP matrix. The NPs showed mean hydrodynamic diameter and drug entrapment efficiency of 178.5 nm and 20.52%, respectively. Owing to its pH-sensitivity, the PCL-NPs showed membrane-lytic behavior upon reducing the pH value of surrounding media to 5.4, which is characteristic of the endosomal compartments. The in vitro antitumor assays demonstrated that MTX-loaded PCL-NPs have higher antiproliferative activity than free drug in MCF-7 cells and, to a lesser extent, in HepG2 cells. This same behavior was also achieved at mildly acidic conditions, characteristic of the tumor microenvironment. Altogether, the results evidenced the pH-responsive properties of the designed NPs, as well as the higher in vitro cytotoxicity compared to free MTX, representing thus a promising alternative for the antitumor therapy.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disorder that has no cure till now. Piperine (PIP) is an alkaloid characterized by memory-enhancing properties but challenging oral delivery obstacles. The objectives of this study are as follows: preparation of microemulsion (ME) as a proposed oral PIP nanocarrier for treatment of Alzheimer's disease and testing its safety on the brain and other internal organs. This study employs bioactive surfactants in the common safe doses to improve PIP targeting to the brain. Selected ME systems encompassed Caproyl 90 (oil)/Tween 80/Cremophor RH 40 (surfactant) and Transcutol HP (co-surfactant). The particle size of the prepared formulations was less than 150 nm with negative zeta potential. The in vivo results showed a superior effect of ME over free PIP. Colchicine-induced brain toxicity results showed the safety of ME on brain cells. Nevertheless, toxicological results showed a potential ME nephrotoxicity. Oral microemulsion increased PIP efficacy and enhanced its delivery to the brain resulting in better therapeutic outcome compared to the free drug. However, the toxicity of this nanosystem should be carefully taken into consideration on chronic use.

Abstract
CONTEXT Nonionic surfactant vesicles have gained increasing scientific attention for hydrophobic drugs delivery due to their biocompatibility, stability and low cost. OBJECTIVE The aim of the present study was to synthesize and evaluate a novel creatinine-based nonionic surfactant in terms of its ability to generate biocompatible niosomal system for the delivery of Clarithromycin. MATERIALS AND METHODS The surfactant was synthesized by reacting creatinine with lauroyl chloride followed by characterization using 1HNMR and MS. The drug-loaded niosomal vesicles of the surfactant were characterized for drug encapsulation efficiency (EE) using LC-MS, vesicle size using dynamic light scattering (DLS) and vesicle shape using atomic force microscopy (AFM). The surfactant was also investigated for blood hemolysis, in vitro cytotoxicity against different cell lines and in vivo acute toxicity in mice. Furthermore, the in vivo bioavailability of Clarithromycin encapsulated in the novel niosomal formulation was investigated using rabbits and quantified through validated LC-MS/MS method. RESULTS AND DISCUSSION Findings showed that vesicles were able to entrap up to 67.82 ± 1.27% of the drug, and were rounded in shape with a size around 202.73 ± 5.30 nm and low polydispersity. The surfactant caused negligible blood hemolysis, very low cytotoxicity and was found to be safe up to 2500 mg/kg body weight using mice. The niosomal formulation showed twofold enhanced oral bioavailability of Clarithromycin as compared to commercial formulations of the drug. CONCLUSION The study has shown that the creatinine-based niosomes developed in our laboratory were biocompatible, safe and increased the oral bioavailability of the model hydrophobic Clarithromycin using experimental animals.

Abstract
There has been an increase in the use of botanicals as skin photoprotective agents. Pomegranate (Punica granatum L.) is well known for its high concentration of polyphenolic compounds and for its antioxidant and anti-inflammatory properties. The aim of this study was to analyze the photoprotection provided by P. granatum seed oil nanoemulsion entrapping the polyphenol-rich ethyl acetate fraction against UVB-induced DNA damage in the keratinocyte HaCaT cell line. For this purpose, HaCaT cells were pretreated for 1h with nanoemulsions in a serum-free medium and then irradiated with UVB (90-200 mJ/cm(2)) rays. Fluorescence microscopy analysis provided information about the cellular internalization of the nanodroplets. We also determined the in vitro SPF of the nanoemulsions and evaluated their phototoxicity using the 3T3 Neutral Red Uptake Phototoxicity Test. The nanoemulsions were able to protect the cells' DNA against UVB-induced damage in a concentration dependent manner. Nanodroplets were internalized by the cells but a higher proportion was detected along the cell membrane. The SPF obtained (~25) depended on the concentration of the ethyl acetate fraction and pomegranate seed oil in the nanoemulsion. The photoprotective formulations were classified as non-phototoxic. In conclusion, nanoemulsions entrapping the polyphenol-rich ethyl acetate fraction show potential for use as a sunscreen product.

Abstract
Engineered nanomaterials are emerging functional materials with technologically interesting properties and a wide range of promising applications, such as drug delivery devices, medical imaging and diagnostics, and various other industrial products. However, concerns have been expressed about the risks of such materials and whether they can cause adverse effects. Studies of the potential hazards of nanomaterials have been widely performed using cell models and a range of in vitro approaches. In the present review, we provide a comprehensive and critical literature overview on current in vitro toxicity test methods that have been applied to determine the mechanisms underlying the cytotoxic effects induced by the nanostructures. The small size, surface charge, hydrophobicity and high adsorption capacity of nanomaterial allow for specific interactions within cell membrane and subcellular organelles, which in turn could lead to cytotoxicity through a range of different mechanisms. Finally, aggregating the given information on the relationships of nanomaterial cytotoxic responses with an understanding of its structure and physicochemical properties may promote the design of biologically safe nanostructures.
