Nanospheres are the particles having the size range between 10-200 nm in diameter. Nanospheres can be amorphous or crystalline in nature and also they have the ability to protect the drug from enzymatic and chemical degradation. It has been shown that the hydrophobic surfaces of these particles are highly susceptible to opsonization and clearance by the reticulo endothelial system. The tiny cap...

objective(s) several antigens, adjuvants and delivery systems have been evaluated for induction of protective immune responses against leishmaniasis, but most of them have been inefficient. in this study, plga nanospheres as antigen delivery system cpg-odn as an immunoadjuvant for increasing the immune responses against autoclaved leishmania major (alm) were prepared and characterized. material...

Inexpensive, easy-to-implement coatings exhibiting extremely low reflectance within a broad spectral range, and good adhesion to substrates are in high demand for high-precision optical instruments solar energy harvesting. Herein, we demonstrate highly absorbing coating based on hollow carbon nanospheres (HCSs). The formed via simple high-performing air-spraying process with tailored paint form...

In a gas membrane, gas is transferred between a liquid and a gas through a microporous membrane. The main challenge is to achieve a high gas transfer while preventing wetting and clogging. With respect to the oxygenation of blood, haemocompatibility is also required. Here we coat macroporous meshes with a superamphiphobic-or liquid repellent-layer to meet this challenge. The superamphiphobic la...

In induction of systemic and mucosal immunity, particulate antigens are more effective than soluble antigens possibly because they are more efficiently endocytosed by mucosal-associated lymphoid tissue (MALT) M cells. In this study, we determined the systemic and mucosal immune responses in rabbits following intranasal immunization of tetanus toxoid TT and CpG-ODN encapsulated within PLGA nanos...

In this work, a facile one-step microwave-assisted method for deposition of monodisperse Ni nanospheres on reduced graphene oxide (rGO) sheets to form Ni-rGO nanohybrids is discussed. In the presence of hydrazine monohydrate, Ni nanospheres are grown onto rGO sheets using nickel precursor and GO as starting materials in ethylene glycol (EG) solution under a low level of microwave irradiation (3...

Incorporation of aromatic motifs into the nanosized shells of hollow carbon nitride nanospheres has been reported to develop functional photosynthetic structures for solar energy application. This modification results in an extended π-conjugation system, red-shift of the optical absorption, and an improved charge separation in the shell, while still retaining the unique hollow polymeric nanoarc...
