Why use liposomes in drug delivery?

Applications of liposome-based formulations and products cover a wide variety of delivery systems as they are able to incorporate a series classes of substances such as anticancer drugs, antiviral, antibacterial, hormones, enzymes, steroids, nucleotides, peptides, proteins and bronchodilators. Liposomes are characterized as an advanced technology to deliver active molecules to the site of action with reduced side effects and enhanced efficacy, which is particularly vital for tumors and inflammations therapy. Advanced liposome delivery undertakes a highly engineered approach that, by tailoring constituent bilayer lipid compositions, lamellarity, bilayer curvature, as well as surface modification, enables active or passive targeting with excellent precision. These modified liposomes can increase circulation time (e.g. stealth liposomes), improve delivery of poorly soluble drugs (e.g. pharmacosomes), and enhance their elasticity through skin penetration (e.g. transferosomes and ethosomes). With the advancement of technologies in medicine, liposomes are expected to play an even more important role in battling with difficulties in formulation development of drug delivery.

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
