A wide range of challenges are faced during the storage of blood products, including storage lesions, contamination that must be removed, and cell and protein damage due to chemicals and UV exposure. The enhancement of stability exhibited by gold nanoparticles (GNPs) is a notable advantage of these nanoparticles for the storage of blood products. The results of our review of articles from 2011 to 2022 discussing the effect of GNPs on blood products revealed that in RBCs, the dose, concentration, amount, and surface charge of GNPs significantly affect their compatibility.

Article Synopsis
  • PEGylation, the process of attaching polyethylene glycol to blood proteins and cells, helps solve issues like short half-life and instability of blood products.
  • Different PEGylation strategies can improve the quality of blood components such as red blood cells, platelets, and albumin by enhancing their stability and preventing unwanted reactions during storage.
  • While PEGylation generally improves stability, the effectiveness can vary; for example, the size of PEG molecules affects how long proteins stay in circulation, and utilizing branched PEG can improve retention for certain antibodies.

Maintaining the quality of platelet products and increasing their storage time are priorities for treatment applications. The formation of platelet storage lesions that limit the storage period and preservation temperature, which can prepare a decent environment for bacterial growth, are the most important challenges that researchers are dealing with in platelet preservation. Nanotechnology is an emerging field of science that has introduced novel solutions to resolve these problems.

Today, Platelets and platelet-derived nanoparticles and microparticles have found many applications in nanomedical technology. The results of our review study show that no article has been published in this field to review the current status of applications of these platelet derivatives so far. Therefore, in the present study, our goal is to compare the applications of platelet derivatives and review their latest status between 2010 and 2020 to present the latest findings to researchers.

Article Synopsis
  • This review study analyzes articles from 2010-2020 regarding the use of chitosan nanocarriers to enhance the effectiveness of amphotericin B (AmB) for treating leishmaniasis, a tropical parasitic disease.
  • Leishmaniasis treatment is complicated by AmB's toxicity and solubility issues, making nanoparticles like chitosan a promising solution to improve drug delivery and reduce side effects.
  • Studies show that loading higher doses of AmB into chitosan nanoparticles increases their effectiveness in inhibiting and killing the Leishmania parasite while also minimizing toxicity, suggesting a viable future treatment option.
