Therefore, the detection and quantitation of antibiotics, i.e., streptomycin by robust, easy, and sensitive methods is in great demand. Among different strategies, new analytical methods for the efficient detection and quantitative determination of streptomycin have been developed. Aptasensors or aptamer-based biosensors have attracted more attention due to their unique recognition, simple fabrication, and significant selectivity, sensitivity, and specificity. Advantages of aptasensors will be highlighted in this review, with emphasis on methodological technique and specific properties of aptasensors developed for STR determination.  In this review paper, we will focus on the recent development of aptasensors for streptomycin detection, considering the papers summarized in the data bases scopus and google scholar covering the period of time from 2013 till 2021.","PeriodicalId":18933,"journal":{"name":"Nanomedicine Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48383150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Available anthrax vaccines have low stability and require multiple injections in order to be effective. Poly lactic acid (PLA) has been approved as a biodegradable and biocompatible polymer for drug and vaccine delivery applications. The purpose of this study is to evaluate the antibody titer against the protective antigen recombinant protein (PA63) encapsulated by the mPEG-PLA double-block copolymers and to compare with the non-encapsulated PA63.Materials and Methods To attain this purpose, to start, the desired protein was purified and confirmed and then PA63 was encapsulated with mPEG-PLA double-block copolymers using a water- oil- water solvent evaporation method. Produced nanoparticles was characterized in terms of morphological specifications using scanning electron microscopy, size and polydispersity index using dynamic light scattering and zeta potential using a zeta seizer. The synthesized nanoparticle antigenic content and also its antigen release profile was measured. In the following, the nanoparticles containing antigens (PA63-NPs), blank nanoparticles (mPEG-PLA- NPs), PA63 and adjuvant control were injected subcutaneously to mice and the IgG polyclonal antibody titr was measured by indirect ELISA. Finally to evaluate biocompatibility and toxicity, synthesized nanoparticles were investigated  by cell culture testing.Results  The results of this study showed that the synthesized nanoparticles are of good quality. ELISA results showed that antibody production titr in mice receiving PA63-NPs was higher than those receiving the PA63 (P<0.05). Cell culture results revealed that the synthesized nanoparticles have no toxicity.Conclusion The findings of the study indicated that the obtained nano vaccine formulations had a higher ability than non-encapsulated recombinant proteins to stimulate the immune system of animal, and that PLA could be used as an appropriate carrier for an effective, stable, safe and biodegradable engineered recombinant vaccine against anthrax.","PeriodicalId":18933,"journal":{"name":"Nanomedicine Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42459550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early diagnosis of cancer may significantly increase the chance of effective treatment. In the recent years, the importance of medical imaging usage has been increased to identify cancer’s nature and pattern of growth in order to provide the most advantageous treatment approaches for cancer tumors. Magnetic resonance imaging is an efficient non-invasive tool for early diagnosis of cancer which provides clear scans of various tissues without radiation. Contrast Agents such as Gadoterate Meglumine enhance contrast MR imaging and provide imaging from inside the cells without entering them.Materials and Methods: In this study, Gadoterate Meglumine nano-sized anionic linear globular dendrimer second generation was first synthesized and then qualitative and quantitative methods were carried out to ensure the proper synthesis and to assess the toxicity of the compound. Once the non-toxicity of the chemical was ensured, in vivo MR imaging studies was performed to test the impact of the synthesized compound on the resolution of image. Results: The result obtained from this study demonstrated that the attachment of Gadolinium (III) to a nano dendrimer reduces its cytotoxicity and also improved resolution of image. In this research, Gadoterate Meglumine nano-sized anionic linear globular dendrimer second generation was effectively able to enter the cells while showing low cytotoxicity in the normal cells and moderate cytotoxicity on cancer cells.

Conventional imaging techniques usually depend on the tissues’ anatomical structure. Epidermal growth factor receptor-2 (HER-2) is a transmembrane protein with an extracellular ligand-binding domain. HER2 plays an essential role in cell proliferation, differentiation, and survival, and its overexpression is associated with various cancers, especially breast and ovarian cancers. Access to its extracellular domain makes HER2 an ideal target for drug preparation and molecular imaging probes. In this study, a targeted magnetic nanoprobe for molecular imaging of HER2 positive cancers was synthesized, and also its potential as a T2-weighted targeted contrast agent was assessed.Materials and Methods: Superparamagnetic SPION nanoparticles were synthesized using the co-precipitation method in the presence of CMD and were labeled with SLTVSPWY peptide. The SPION@CMD@SLTVSPWY nanocomplex was characterized by TEM, DLS, XRD, AAS, FTIR, EDX, and VSM. The r1 and r2 relaxivities were then calculated using a 1.5 Tesla clinical magnetic field. The cytotoxicity of the nanocomplex was evaluated by MTT assay. Finally, the difference between uptake of targeted nanocomplexes and SPION by the human SKOV-3 cell line (HER2 +) was investigated.Results: The SPION@CMD NPs were synthesized with spherical shape and superparamagnetic behavior. Characterization results confirmed the formation of SPION@CMD@SLTVSPWY.  r2 relaxivity and r2/r1 calculations resulted in suitable values of 313 mM-1s-1 and 8.05 for SPION@CMD@SLTVSPWY, respectively. Increased uptake of targeted nanocomplexed (SPION@CMD@SLTVSPWY) compared to non-targeted NPs (SPION@CMD) was very noticeable visually, and its numerical ratio was 3.51 at a concentration of 0.075 mM.  Conclusion: The targeted synthesized nanocomplex in this study has great potential as a T2 weighted probe contrast agent in MR imaging owing to its appropriate high uptake in HER2 + cells.","PeriodicalId":18933,"journal":{"name":"Nanomedicine Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42717275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to prepare a targeted nano-carrier for co-delivery of doxorubicin (Dox) and gene using polyethylenimine. Materials and Methods: In order to prepare the ligand-containing polymer conjugates, succinic anhydride was conjugated onto the hydroxyl group of Dox through an ester bond following the protection of Dox amines by Fmoc. Drug-polymer conjugates were then coupled with L-DOPA in order to prepare the targeted nanocarriers to the cells through Large Amino Acid Transporter-1 (LAT-1). The PEI derivatives were characterized using 1H-NMR. The toxicity of conjugated polymer, Dox and PEI was assessed on HepG2 and A375 cell lines with different expression level of LAT-1 transporters using MTT assay. Results: The chemical structure of PEI conjugate was confirmed by 1H-NMR. The cytotoxicity measurement demonstrated a cell line-dependent toxicity profile at the concentrations tested in this study. It was shown that there was no significant difference in cell-induced toxicity between conjugated polymer and its parent form in A375 cell line while the cytotoxicity of conjugated polymer was significantly lower than the parent PEI in HepG2 cells.Conclusion: These results provide promising evidence for further evaluation of PEI conjugate for co-delivery of drug and gene via LAT-1 transporters.","PeriodicalId":18933,"journal":{"name":"Nanomedicine Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46497236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
