The Journal for NanoScience and Nanotechnology Education or Nanoeducation literature have been included in section part of ‘Journal of Materials NanoScience‘ under NanoEdu section.
The faculty members now can published their literary work required for teaching and learning of NanoScience and Nanotechnology concepts. The following type of work will be considered for publication
Lecture Notes: for undergraduate level or postgraduate level.
Chapters : Detailed chapters in field of nano.
Practical experimental details: If you are conducting experiments as part of curriculum study, then you can submit the details of experiments for undergraduate as well as postgraduate courses.
The chapters or NanoEdu articles should be prepared as per journal guidelines and submit on the journal site in NanoEdu section
In this study, we have prepared a novel, dual-biomarker, targeting ligand having high affinity and specificity for PSMA/GRPr receptors that are expressed on most prostate cancers. [DUPA-6-Ahx-Lys(DOTA)-6-Ahx-RM2] was synthesized and the new conjugate was metallated macroscopically with GaCl3, InCl3, and LuCl3 to form [DUPA-6-Ahx-Lys(M-DOTA)-6-Ahx-RM2] (where M = Ga, In, or Lu). These new agents, when radiolabeled with Ga-68, In-111, or Lu-177 hold theranostic potential for patients presenting with prostate cancer disease.
In this paper we report the synthesis of 68Ga labeled NODAGA-Erlotinib for imaging of EGFR over-expressing tumors. NODAGA-Erlotinib conjugate was synthesized by reaction of the terminal alkyne of Erlotinib using Cu catalyzed click reaction. The conjugate was then radiolabeled with 68Ga in high radiochemical yields. The 68Ga NODAGA-Erlotinib conjugate also exhibited high in vitro stability. The log P value of 68Ga-NODAGA-Erlotinib was lower than that of 68Ga-NOTA-Erlotinib, a 68Ga based Erlotinib conjugate previously reported by our group. In the in vitro cell binding studies carried out in EGFR-positive A431 cells, 68Ga-NODAGA-erlotinib exhibited an uptake (7.8±1.3 %) lower than that of 68Ga-NOTA-Erlotinib (9.8±0.4%) showing that an increase in hydrophilicity possibly effected a decrease in cell permeability. The higher hydrophilicity of 68Ga-NODAGA-Erlotinib also led to significantly lower accumulation of 68Ga-NODAGA-Erlotinib in non-target organs in the biodistribution studies in Swiss mice. The overall properties of the 68Ga-NODAGA-Erlotinib conjugate are promising and reflect the role of hydrophilicity in reducing the non-specific uptake of the final radiotracer towards improving signal/noise ratio for further imaging studies.

Applications of Nanoparticles and nanopharmulations in drug development and drug delivery have been an extensive field of research to find out the alternative better therapeutics. The past research in nanomedicine and nanobiotechnology mostly emphasized on improving the profile of existing drugs, however, a recent pattern has seen in variation of field and aspects studied using nanomedicine. The current nanomedicine research has oriented in developing new drugs based on the interaction of nanoparticles on targets like cancer therapeutics, development of new biosensors, bioimaging (cellular and in vivo), new vistas of anti-viral drugs, besides the most researched field of nano delivery of drugs for cancer, diabetes, anti-bacterial, and other ailments. An overview of current research trends is presented based on the literature published at different platforms in recent time.

Khurana, Amita Malik, Chetan Sharma, Harsh Panwar A series of novel 2-(3-aryl/alkylaminopropoxy)-12-aryl-9,10-dihydro-8H– benzo[a]xanthen-11-one derivatives were synthesized from 2-hydroxy-12-aryl 9,10-dihydro-8H-benzo[a]xanthen-11-ones by reaction with 1-bromo-3-chloropropane in presence of K2CO3 in dry acetone under reflux followed by reaction with aryl/alkyl amines in presence of KI in dry DMF at 100oC. Structures have been confirmed by spectroscopic analysis. All the newly synthesized 2-(3- aryl/alkylaminopropoxy)-12-aryl xanthene derivatives were screened for their antimicrobial activity against four microbial strains Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. The selected synthesized compounds showed moderate antimicrobial activity.
