“…in our opinion, by using nano-technological therapeutic agents during cancer treatment will represent a great potential and hope for successful cancer therapy in near future. As an application, here we discussed how a nano-robot agent can able to diagnose and kill the specific cancer cell [12][13][14] by controlled drug transfer to particular site. The result, we have obtained from our research work are validated with the clinical findings and only with some minor enhancement in some fields, the final result will give satisfactory output.…”

In developed countries, one of the major causes in cancer-related deaths among women are due to Metastatic breast cancer (MBC). Some of the many challenges one faced are diagnostic and therapeutic limitations. The causes of these limitations are due to tumor heterogeneity and also various physiological barriers that make drug delivery to specific metastatic sites difficult. To overcome such challenges, targeted nanoparticles are used. The targeted nanoparticles are exploited for surface fictionalization, and can be directed towards tumor markers and tissue-specific metastases. These targeted nanoparticles techniques may provide an effective tool towards treatment for Metastatic breast cancer (MBC) related patients in case of lowvascularised and small-sized metastases. In this article we considered surface fictionalization nanoparticles as nono machines and presents an approach to control them at the nano-meter or molecular scale (10-9 meter) in the perspective of the theory of cybernetics, the science of control, communication and computation. In this paper, we discuss a specific method of special autonomous nano-robotic systems which can be used for bio-mechanical and bio-medical purposes. We have considered a fuzzy shaped based approach in describing how a single malignant cell can be recognises along with its stage, as a suitable target for medical treatment. After synthesis and imaging of magnetic nanoparticles is complete, functional binding of the magnetic nanoparticles with its medicine takes place which is then directed towards effected regions for targeted drug delivery. Such as in this case cancer treatment which is also presented specially to metastatic breast cancer treatment. The result portrays its massive potential in upcoming transition of the research work into practical clinical practice for an effective diagnosis and treatment of the disease in near future.

The self-assembly of nanoparticles is a prominent strategy for fabricating nanomaterials and nanodevices. Herein, FePt-based nanoparticles are self-assembled at a diethylene glycol-air interface, under an applied in-plane static magnetic field. The effect of the field on the self-assembly is apparent at a field strength of 60 mT, whereby nanoparticles arranged into randomly oriented nanoparticle chains. Increasing the field strength to 90-120 mT resulted in the nanoparticle chains becoming increasingly disintegrated, and large islands form at the expense of the uniform nanoparticle monolayer. The pattern arising from self-assembly is described based on the drag force and ligand-ligand interactions, which compete with van der Waals forces and magnetic dipole interactions induced by the applied magnetic field.

“…Nanometer (1x10 -9 m to 100x10 -9 m) sized particles are of today's interests because of their shape and size-dependent (Karan et al, 2012) physical properties. The chemical and physical properties of such aggregates, comprising only a few hundred atoms are in a transition region between the bulk and individual atomic or molecular properties (Dutta Majumder et al, 2007).…”

This article presents a systematic study of the effect of size and shape on the spectral response of individual nanoparticles (NPs). When developing NPs as catalysts, their shape is very important. For a certain volume of material, nanoparticles make the best catalysts when they have a large surface area. It is a challenge to find the shape that has the largest surface area for its volume. The main focus of this paper is the interesting change in properties of the materials due to increase surface area to its volume. The particle shape contours were measured by transmission electron microscope with high resolution. These TEM images are analyzed with image clustering techniques and generalized shape theory that results the computational indicators for shape, degree of atomic compactness of NPs. These types of characterization help the researchers in sizebased spectral tuning, biological labeling, and toxicity studies and suggest general protocols to address these problems.
