Porous hollow glass microspheres have many uses, including encapsulation of active materials. In this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. Then, a highly reactive amine was infiltrated into the etched glass microspheres. Scanning electron microscopy was conducted for the hollow glass micr...

Leptospirosis is one of the most prevalent zoonotic diseases worldwide. Currently, multivalent whole-cell leptospiral vaccines can induce protection against leptospirosis. Therefore, preparation and formulation of new generations of vaccines that can stimulate long-term immunity for leptospirosis control are essential. The aim of this study was to prepare and characterize alginate microspheres ...

  Objective: In dental treatments, use of carriers for targeted antibiotic delivery would be optimal to efficiently decrease microbial count. In this study, gentamicin was loaded into polylactic co-glycolic acid (PLGA) microspheres and its release pattern was evaluated for 20 days.   Methods: In this experimental study, PLGA microspheres loaded with gentamycin were produced by the W/O/W method....

     In this study, microspheres containing estradiol valerate were prepared by solvent evaporation method using poly (glycolide-co-lactide) (PLGA 50:50) and poly (lactide). The effect of different process variables such as polymer type, drugpolymer ratio, stirring rate, volume of internal phase and temperature of external phase on the morphology, particle size distribution, encapsulation effic...

Abstract Developing latent fingerprints is extremely significant for personal identification and criminal investigation. Sub‐micrometer core‐shell structured magnetic fluorescent composite which combines the merits of noncontact responsiveness strong fluorescence emission highly desired visualization fingerprint on various substrates with high resolutions. However, it remains a great challenge ...

Halide perovskites are extremely interesting semiconductors for innovation in optoelectronics and photovoltaics. In particular, they efficient emitters of both incoherent coherent light and, therefore, interest as active materials lasers, amplification systems (resonators waveguides), other photonic devices. Here, we present a set experimental results concerning nonlinear effects the radiative ...

Current materials used for adipose tissue reconstruction have critical shortcomings such as suboptimal volume retention, donor-site morbidity, and poor biocompatibility. The aim of this study was to examine a controlled delivery system of dexamethasone to generate stable adipose tissue when mixed with disaggregated human fat in an athymic mouse model for 6 months. The hypothesis that the contin...

Microencapsulation of biological and chemical agents and species (e.g., drugs, proteins, vitamins, cells, fragrances, and flavors) is of great importance to many applications ranging from food and pharmaceutical industry to inkless paper. Particularly, liquid core-polymer shell microcapsules have emerged attracting much attention. This is because using polymer shell makes microcapsules more sta...
