Abstract
The goal of this review is to present enzymosomes as an innovative means for site-specific drug delivery. Enzymosomes make use of an enzyme's special characteristics, such as its capacity to accelerate the reaction rate and bind to a particular substrate at a regulated rate. Enzymosomes are created when an enzyme forms a covalent linkage with a liposome or lipid vesicle surface. To construct enzymosomes with specialized activities, enzymes are linked using acylation, direct conjugation, physical adsorption, and encapsulation techniques. By reducing the negative side effects of earlier treatment techniques and exhibiting efficient medication release, these cutting-edge drug delivery systems improve long-term sickness treatments. They could be a good substitute for antiplatelet medication, gout treatment, and other traditional medicines. Recently developed supramolecular vesicular delivery systems called enzymosomes have the potential to improve drug targeting, physicochemical characteristics, and ultimately bioavailability in the pharmaceutical industry. Enzymosomes have advantages over narrow-therapeutic index pharmaceuticals as focusing on their site of action enhances both their pharmacodynamic and pharmacokinetic profiles. Additionally, it reduces changes in normal enzymatic activity, which enhances the half-life of an enzyme and accomplishes enzyme activity on specific locations.

Abstract
As the field of nanoscience is rapidly evolving, interest in novel, upgraded nanomaterials with combinatory features is also inevitably increasing. Hybrid composites, offer simple, budget-conscious and environmental-friendly solutions that can cater multiple needs at the same time and be applicable in many nanotechnology-related and interdisciplinary studies. The physicochemical idiocrasies of dendritic polymers have inspired their implementation as sorbents, active ingredient carriers and templates for complex composites. Ceramics are distinguished for their mechanical superiority and absorption potential that render them ideal substrates for separation and catalysis technologies. The integration of dendritic compounds to these inorganic hosts can be achieved through chemical attachment of the organic moiety onto functionalized surfaces, impregnation and absorption inside the pores, conventional sol-gel reactions or via biomimetic mediation of dendritic matrices, inducing the formation of usually spherical hybrid nanoparticles. Alternatively, dendritic polymers can propagate from ceramic scaffolds. All these variants are covered in detail. Optimization techniques as well as established and prospected applications are also presented.

Abstract
Proteins and peptides have a great potential as therapeutic agents; they have higher efficiency and lower toxicity, compared to chemical drugs. However, their oral bioavailability is very low; also, the transdermal peptide delivery faces absorption limitations. Accordingly, most of proteins and peptides are administered by parenteral route, but there are many problems associated with this route such as patient discomfort, especially for pediatric use. Thus, it is a great challenge to develop drug delivery systems for administration of proteins and peptides by routes other than parenteral one. This review provides an overview on recent advances adopted for protein and peptide drug delivery, focusing on oral and transdermal routes. This is followed by an emphasis on two recent approaches adopted as delivery systems for protein and peptide drugs, namely aquasomes and microneedles. Aquasomes are nanoparticles fabricated from ceramics developed to enhance proteins and peptides stability, providing an adequate residence time in circulation. It consists of ceramic core coated with poly hydroxyl oligomer, on which protein and peptide drug can be adsorbed. Aquasomes preparation, characterization, and application in protein and peptide drug delivery are discussed. Microneedles are promising transdermal approach; it involves creation of micron-sized pores in the skin for enhancing the drug delivery across the skin, as their length ranged between 150 and 1500 μm. Types of microneedles with different drug delivery mechanisms, characterization, and application in protein and peptide drug delivery are discussed. Graphical abstract.

Abstract
Aquasomes, a new drug delivery system comprised of surface-modified nanocrystalline ceramic carbohydrate composites, was developed to serve as haemoglobin carrier for oxygen delivery. The hydroxy-apatite ceramic core was prepared by coprecipitation and self-precipitation and coated with various sugars like cellobiose, maltose, sucrose, and trehalose. The effect of drying methods, i.e., air drying, vacuum drying, and lyophilization, on the degree of binding was studied by concanavalin-induced aggregation method. Haemoglobin was adsorbed over the sugar-coated ceramics, and percent loading was estimated by benzidine method. The adsorption of sugars on calcium hydro-apatite powder and haemoglobin adsorption on sugar-adsorbed ceramic followed both Freundlich and Langmuir isotherm. The haemoglobin aquasome formulations (equivalent to 7.5% Hb) were suspended in a phosphate buffer containing 7.5% w/v albumin and 0.01% w/v lecithin, and they were evaluated for oxygen-carrying capacity, which was found to be similar to fresh blood. The Hill coefficients were found to be fairly good for its use as oxygen carrier. The haemoglobin aquasome formulations did not induce haemolysis of red blood cells nor alter the blood coagulation time. The haemoglobin content of the formulation remained unchanged on storage for 30 days. The haemoglobin desorption was fairly low under shear conditions, indicating good stability of formulation in biological system. During in vivo study in rats the survivals were monitored as function of hematocrit in rats receiving isovolemic exchange transfusion. Arterial blood pressure and heart rate did not change significantly in animals transfused with aquasomal suspension on 50% exchange transfusion.

Abstract
The aim of this study was to prepare nanoparticles in form of aquasomes with Indomethacin as a low solubility drug mode. Aquasomes charged with Indomethacin were obtained through the formation of an inorganic core of calcium phosphate covered with a Lactose film and further adsorption of the Indomethacin. Structural analyses, particle size, and morphology were evaluated by X-ray powder diffractometry, transmission electron microscopy, and scanning electron microscopy. The X-ray analysis of the samples and their observation through electronic microscopy allowed us to identify the inorganic calcium phosphate nucleus formation, as well as the layers of Lactose and Indomethacin. The particle size analysis of the aquasomes obtained with the Lactose layer and charged with the drug indicated an average particle size in the range of 60-120 nm, with a media of 90 nm. Standard deviation was 18.0234 and the standard error of the media 4.1348. The method was reproducible under the conditions used to prepare the aquasomes, such as ultrasound frequency and the moment of sonication for the formation of inorganic cores.

Abstract
The progress toward subunit vaccines has been limited by their poor immunogenicity and limited stability. To enhance the immune response, subunit vaccines universally require improved adjuvants and delivery vehicles. In the present study, we propose the use of ceramic core based nanodecoy systems for effective immunization, which seems to exhibit a broad range of surface properties. Nanodecoy systems were prepared by self-assembling of hydroxyapatite core and cellobiose and finally the hepatitis B surface antigen (HBsAg) was adsorbed over the preformed nanodecoy systems. HBsAg loaded nanodecoy systems were characterized for size, shape and antigen loading efficiency. The effect of processing steps on the stability and integrity of HBsAg was assessed by in vitro antigenicity and SDS-PAGE experiments. Nanodecoy preparations were nanometric in size range and almost spherical in shape. SDS-PAGE studies confirmed the integrity of HBsAg protein in the formulation. Vaccine efficacy was determined in female Balb/c mice and results indicated that specific anti-HBsAg antibody titers in mice receiving nanodecoy system were more efficient than the conventional adjuvant alum followed by subcutaneous immunization. Studies also indicated that nanodecoy formulations could elicit combined Th1 and Th2 immune response. It is inferred that nanodecoy systems are a class of novel carriers and hold potential as an alternative adjuvant in vaccine technology.

Abstract
Applications of nanotechnology for treatment, diagnosis, monitoring, and control of biological systems has recently been referred to as "nanomedicine" by the National Institutes of Health. Research into the rational delivery and targeting of pharmaceutical, therapeutic, and diagnostic agents is at the forefront of projects in nanomedicine. These involve the identification of precise targets (cells and receptors) related to specific clinical conditions and choice of the appropriate nanocarriers to achieve the required responses while minimizing the side effects. Mononuclear phagocytes, dendritic cells, endothelial cells, and cancers (tumor cells, as well as tumor neovasculature) are key targets. Today, nanotechnology and nanoscience approaches to particle design and formulation are beginning to expand the market for many drugs and are forming the basis for a highly profitable niche within the industry, but some predicted benefits are hyped. This article will highlight rational approaches in design and surface engineering of nanoscale vehicles and entities for site-specific drug delivery and medical imaging after parenteral administration. Potential pitfalls or side effects associated with nanoparticles are also discussed.

Abstract
Spherical hydroxyapatite cores were prepared by using carboxylic acid terminated half-generation poly(amidoamine) (PAMAM) dendrimer as templates or crystal modifiers. The hydroxyapatite cores were characterized by infrared spectroscopy (IR), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The spherical core formation depended on phosphate saturation, pH of the simulated body fluid (SBF) and rate of crystal growth. Hydroxyapatite so formed was amorphous and a mixture of various calcium phosphates. Ca/P ratio determination which showed phosphate rich apatite formation. Hydroxyapatite ores were coated with a sugar layer followed by hemoglobin to obtain aquasomes. Aquasomes were characterized for size, hemoglobin loading, oxygen-binding characteristics and storage stability. The nanometric sized aquasome formulation could load approximately 13.7 mg hemoglobin per g of core and retained oxygen-affinity and cooperativity and stability for at least 30 days. Formulation efficacy was tested in albino rats and indicated its potential utility as blood-substitute.

Abstract
The insulin-bearing aquasomes were fabricated by first preparing the nanosize calcium phosphate dihydrate core. The calcium phosphate dihydrate core was prepared by colloidal precipitation and sonication of disodium hydrogen phosphate solution and calcium chloride solution at low temperature. This core was coated with cellobiose, pyridoxal-5-phosphate, or trehalose under sonication and was further loaded with the drug at low temperature by a partial adsorption mechanism. The prepared systems were characterized for size, shape, size distribution, drug loading efficiency, and in vivo performance. The in vivo performance of the formulated aquasome was compared with standard porcine insulin solution, and better results were observed compared to insulin solution.
