In this study the ability of spherical particles (SPs) obtained from the tobacco mosaic virus (TMV) virions to enhance the immunogenic potential of the vaccine was evaluated. TMV SPs were shown to increase the protective properties of the widely used effective Russian adjuvant-free rabies vaccine, composed of killed rabies virions. The results of the NIH potency test showed enhancement of protectivity, that is comparable with the effect of the incomplete Freund׳s adjuvant on the same vaccine.

Background: Chitosan nanoparticles (CsNPs) are an effective and inexpensive approach for DNA delivery into live cells. However, most CsNP synthesis protocols are not optimized to allow long-term storage of CsNPs without loss of function. Here, we describe a protocol for CsNP synthesis, lyophilization, and sonication, to store CsNPs and maintain transfection efficiency.

The synergistic optical, electronic, and chemical properties of metal nanoparticles present in close proximity have potential applications in energy, medicine, and sustainability. Fundamental studies and application development based on spontaneous self-assembly of one-dimensional (1D) chains of metal nanoparticles without external organization agencies have been pursued for over four decades. The spontaneous formation of 1D chains in a solution of stabilized spherical nanoparticles may be driven by the emergence of local anisotropy due to dipolar interaction, representing a trapped non-equilibrium state.

Gold nanoparticles are widely used in biomedical applications due to their unique properties. However, traditional synthesis methods generate contaminants that cause cytotoxicity and compromise the biocompatibility of the nanomaterials. Therefore, green synthesis methods are essential to produce pure and biocompatible nanoparticles, ensuring their effectiveness in biomedical applications.

Traditional drug-delivery methods are limited by low bioavailability and nonspecific drug distribution, resulting in poor therapeutic efficacy and potential risks of toxicity. Mesoporous silica nanoparticles (MSNs) have attracted wide attention as drug-delivery carriers due to their large specific surface area, adjustable pore size, good mechanical strength, good biocompatibility, and rich hydroxyl groups on their surface. In this paper, MSNs were synthesized by a template method, and the morphology and pore structure were regulated.
