Modifications of the polymer surface aimed at improving cell adhesion and interaction

Aneliya Kostadinova*; Ivan Keranov

The most commonly used biomaterials are polymers – natural (collagen, laminin, chitosan) or synthetic (polylactide, polyethylene oxide, polyglutamate, etc.), which have certain (appropriate) mechanical properties, but most importantly, they are biodegradable. Chemical polymers have recently been preferred and displaced natural ones such as donor skin, collagen, bone implants, etc...

New trends of antimicrobial packaging applying nanotechnology

Rennan Felix da Silva Barbosa; Derval dos Santos Rosa*

Modernity has brought great comfort for society but to maintain that there is a continually increasing demand especially with population growth. One major concern is associated with the food demand that is rising fast, especially for emerging countries, particularly in Asia, Eastern Europe, and Latin America [1]. The Food and Agriculture Organization of the United Nations (FAO) and the International Food Policy Research Institute (IFPRI) have published projections of an increase in global food demand out to 2050 with projections that indicate that world food demand may increase by 70 percent by 2050...

Nanotechnology: Applications, techniques, approaches, & the advancement in toxicology and environmental impact of engineered nanomaterials

Sumera Zaib*; Jamshed Iqbal

Nanoscience refers to the handling of materials, systems and devices at atomic, molecular and macromolecular level, whereas, nanotechnology is the cluster of techniques involved in design, synthesis, characterization and application of structures, materials, devices and systems by manipulating shape and size at nanometer scale. At nanometer level, individual molecules and interaction between them becomes important in comparison with the macroscopic properties of the material or device...

Applications of mesoporous material for drug delivery

Nasir Vadia*; Sadhana Rajput

In recent years mesoporous silica is gaining attention because of their emerging applications in drug delivery. Since their first appearance in materials science in the 1990s, these inorganic carriers have been successfully used in other areas such as catalysis, purification, and adsorption. The majority of ordered MSNs have two-dimensionally ordered arrays of cylindrical pores of uniform size disposed parallel to each other and separated by thin walls.
