Liposomes are spherical lipid vesicles with a bilayered membrane structure composed of natural or synthetic amphiphilic lipid molecules. Nano- Liposomes and lipid nanoparticles (LNPs) are similar by design, but slightly different in composition and function. Both are lipid nanoformulations and excellent drug delivery vehicles, transporting cargo of interest within a protective, outer layer of lipids. Triethylenetetramine (TETA) shows very poor CNS penetration because of the tight junctions of the blood-brain barrier and the ATP-driven efflux transporters. Liposomes were discovered in the 1960s. Among different nanomedicines, liposomes as spherical nanoparticles (NPs) have a particular structure. This review focuses on two nanotechnological drug delivery methods, liposomes and drug-conjugated nanoparticles. Here we have demonstrated that Sn/CD169 ligand decorated nanoparticles is an efficient alternative to the use of anti-Sn antibody as a means for delivery of antigens to macrophages. Lipid nanoparticles (or solid lipid nanoparticles) are simply nanoparticles that are composed of lipids. Lipid nanoparticles (LNPs) have emerged as a powerful non-viral carrier for drug delivery. Liposomes and lipid nanoparticles are similar in design, but slightly different in composition and function. In general, surface modification of nanomaterials and targeted drug delivery remain current research hotspots. Introduction.

Liposome Preparation. In liposomes, LIPOSOMES AND NANOPARTICLES Presented by G.PAVANI. Transfersomes and Ethosomes Production. Magnetic liposomes appear to be a versatile delivery system due to the biocompatibility, capabilities of the surface functionality and their potential for the combination of drug delivery and hyperthermia treatment of cancers. Nanoscale drug delivery systems using liposomes and nanoparticles are emerging technologies for the rational delivery of chemotherapeutic drugs in the treatment of cancer. Liposomes are spherical vesicles characterized by a bilayer of lipids with an internal aqueous cavity, being one of the most successful drug delivery systems With the prevalence of respiratory diseases, particularly highlighted by the current COVID-19 pandemic, investigations into applying LNPs to deliver inhaled therapeutics directly to the lungs are underway. The need for antibiotics with greater intracellular efficacy led to the development of endocytosable drug carriers, such as liposomes and nanoparticles, which mimic the entry path of the bacteria by penetrating the cells into phagosomes or lysosomes. Among them, nano-structured lipid carriers and solid lipid nanoparticles (SLNs) are dominant, which can be modied to exhibit various advantages, compared to liposomes and polymeric nanoparticles. Liposomal nanoparticles were successfully formed using this continuous processing system; along with, concentrating/buffer exchange and remote loading of the drug substances as a single unit step. Polymeric nanoparticles that can easily be modified to suit the needs not only act as a vehicle to efficiently deliver the drug to the target site but also enhance the bioavailability of the drug. INTRODUCTION DEFINITION: Nanoparticles are sub- nano sized colloidal structures composed of synthetic or semi synthetic polymers with a size smaller than 1mm. A method for promoting the controlled binding and release of a bioactive or pharmaceutical agent from a composition comprising silicon nanoparticles, wherein the silicon nanoparticles comprise at least 50% by weight silicon, the method comprising treating the surface of the silicon nanoparticles with at least one lipid, and treating the surface of the silicon nanoparticles with Biotechnology Industry. LIPOSOMES AND NANOPARTICLES Presented by G.PAVANI. Liposomes are composed of one or more closed shells, or lamellae, made of a phospholipid bilayer and enclosing a small volume of aqueous liquid.

Liposomes diameter ranges from tens Exelead develops and manufactures LNPs to encapsulate different types of genetic payloads including siRNA, mRNA and saRNA. Traditional liposomes include one or more rings of lipid bilayer surrounding an aqueous pocket, but not all LNPs have a contiguous bilayer that would qualify them as lipid vesicles or liposomes. Liposomes. Liposomes and lipid nanoparticles (LNPs) are similar by design, but slightly different in composition and function.

Liposomes, an early version of LNPs, are a versatile nanomedicine delivery platform. Liposomes are spherical vesicles formed mainly by phospholipids and other physiologic lipids, while lipid nanoparticles are solid particles at room and body temperature, consisting of solid lipids (SLN) or a mixture of a solid lipid and a liquid lipid (NLC). A number of liposomal drugs have been approved and applied to medical practice.
