Background: Nanotechnology has significantly altered human life in numerous ways, particularly in the field of medicine. It is one of the more recent branches from which you can benefit. In the mechanism for delivering drugs, it is crucial. In this review, we primarily concentrate on the many strategies and methods for administering drugs to any specimen while utilising biocompatible nanomaterials. In the review article, a different feature of nanoparticles and information on the drug delivery method are covered. It is put through both traditional and cutting-edge medication delivery methods, like targeted drug administration. Additionally, the chemistry of drug delivery systems such nanocapsules and unilamellar lipid vesicles is covered. Additionally, various drug profiles and the impact of nanotechnology on transdermal and Blood-Brain Barrier drug delivery systems, as well as the superiority of targeted drug administration over other types of drug delivery systems, are also examined. In order to investigate safety limits, this review paper compiles an extensive overview of the drug delivery system and the fundamental concepts supporting the use of nanoparticles in drug administration. The description of the created methodologies and procedures makes a contribution to the future trends and limitations in this field of research.

Due to the advantages of material abundance and synthetic simplicity, polyaniline can be used as a high-capacity cathode material. However, its practical application in batteries has been hindered by poor electrochemical utilization and cycling instability. This paper reports the enhancement in the conductivity of the polymer (PAni) using the oxidation polymerization method. After successfully synthesis of PAni the vibrational properties have been analyzed by using FTIR. From experimental data, it has been observed that after doping of BaTiO3 the carriers along the surface enhanced which increases vibration along with the fingerprint reason. The polymers showed less electrical conductivity than polyaniline. Unlike polyaniline, the presence of the nitro group caused higher frequency dependence of electrical conductivity. The FTIR bands at 1492, 1291 and 1147 cm−1 are corresponding to the polyaniline salt.
