Pepstatin A

(1) Background: Nanomedicine has recently emerged as a new area of research, particularly to fight cancer. In this field, we were interested in the vectorization of pepstatin A, a peptide which does not cross cell membranes, but which is a potent inhibitor of cathepsin D, an aspartic protease particularly overexpressed in breast cancer. (2) Methods: We studied two kinds of nanoparticles. For pepstatin A delivery, mesoporous silica nanoparticles with large pores (LPMSNs) and hollow organosilica nanoparticles (HOSNPs) obtained through the sol–gel procedure were used. The nanoparticles were loaded with pepstatin A, and then the nanoparticles were incubated with cancer cells. (3) Results: LPMSNs were monodisperse with 100 nm diameter. HOSNPs were more polydisperse with diameters below 100 nm. Good loading capacities were obtained for both types of nanoparticles. The nanoparticles were endocytosed in cancer cells, and HOSNPs led to the best results for cancer cell killing. (4) Conclusions: Mesoporous silica-based nanoparticles with large pores or cavities are promising for nanomedicine applications with peptides.

Maize Cobs

Silica has found applications in many industries. Its production from agricultural wastes has been reported but with marked agglomeration of the final product. This work investigated production of silica nanoparticles from maize cob and effect of sol-gel modification with ethylene glycol on degree of agglomeration was also examined. This work also explored the effects of acid pre/post calcination treatments of the maize cob. Maize cob was treated with HCl prior to and after calcination. Using sol-gel method, silica was produced from both untreated and treated maize cobs. Ethylene glycol was also added to sodium silicate prior to precipitation of silica gel for modification of the conventional sol-gel procedure. The results showed that acid treatments affect the purity of silica nanoparticles. Ethylene glycol was observed to reduce degree of agglomeration in silica nanoparticles production from agricultural wastes. Silica nanoparticles of sizes between 5 and 50 nm were successfully synthesized. Keywords: Agricultural Wastes, Maize cob, Amorphous silica, Agglomeration, Sol-gel, Acid pre-treatment.
