Lipid Nanostructured Particles as Emerging Carriers for Targeted Delivery of Bioactive Molecules: Applications in Food and Biomedical Sciences (An Overview)

Patricia MUNTEAN, Carmen SOCACIU, Mihai Adrian SOCACIU

Abstract


Lipid nanoparticles are getting a growing scientific and technological interest, worldwide. Either Solid Lipid Nanoparticles (SLNs), Nanostructured Lipid Carriers (NLCs), Lipid Drug Conjugates (LDCs) or Polymer-Lipid Nanoparticles (PLNs) have been produced and investigated last years, being reccomended as emerging carrier systems for many food and biomedical applications. An overview of the last publications, mainly since 2017 is presented, underlying the most important methods and techniques used for their preparation (e.g. high shear homogenization in hot and cold conditions, ultrasound assisted melt emulsification) as well techniques applied for measuring the size, calorimetric properties, zeta-potential, etc. Most relevant data related to the use of food-grade ingredients and designed lipid nanoparticles as delivery systems for organic and inorganic bioactive molecules in food or packaging’s are presented. The major reason for this trend in food science is the aim to overcome problems associated with the low bioavailability of many lipophilic bioactive compounds which are claimed to bring benefits to human health (carotenoid or anthocyanin pigments, sterols, vitamins). Finally, the recent applications of different formulas of lipid nanoparticles as drug carriers for in vitro experiments or for in vivo therapy (oral, parenteral or transdermal formulas) are presented.

Keywords
