cell based therapeutics is one of the most rapidly advancing medical fields, bringing together a range of fields including transplantation, tissue engineering and regeneration, biomaterials and stem cell biology. however, traditional cell-based therapeutics have many limitations, one of which is their harmful effects exhibited on healthy body cells due to their lack of specificity. nanomedicine...

A novel magnetic nanoparticle-based electrochemical immunoassay of carcinoembryonic antigen (CEA) was designed as a model using CEA antibody-functionalized magnetic beads [DNA/Fe(3)O(4)/ZrO(2); Fe(3)O(4) (core)/ZrO(2) (shell) nano particles (ZMPs)] as immunosensing probes. To design the immunoassay, the CEA antibody and O-phenylenediamine (OPD) were initially immobilized on a chitosan/nano gold...

Nanotechnology has proposed many new effective forms of nutritional supplement ingredients due to their low toxicity and high bioavailability, among which are nano-selenium, distinctive properties small particles increased surface area ​​compounds, allowing the opportunity for biological interactions. In this study, 48 laying hens, aged 47 weeks, a rose type were used, experiment lasted two mon...

A watermelon-like internally inflated core-buffer-shell structural Si/electrochemically exfoliated graphene/C (Si/EG/C) composite is designed and prepared by the industrially established ball milling spray drying method. Owing to numerous folds voids in EG filled between nano silicon carbon shell, volume fluctuations of inside Si/EG/C particles are buffered lithium ions also could transport fas...

Silicon (Si) is recognized as a promising anode material for high-energy-density lithium-ion batteries. However, under condition of electrode comparable to commercial graphite anodes with low binder content and high density, the practical use Si limited due huge volume change associated Si-Li alloying/de-alloying. Here, we report novel core-shell composite, having reversible capacity ~ 500 mAh ...

Colorectal cancer (CRC) is the third most frequently occurring tumor in human population. CRCs are usually adenocarcinomatous and originate as a polyp on inner wall of colon or rectum which may become malignant due course time. Although therapeutic options CRC limited, early diagnosis play an important role preventive interventions to decrease mortality rate. The CRC-affected tissues exhibit se...

Introduction In this study, we describe the results of controlled synthesis and application of gold coated Fe3O4/SiO2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (SPR) Phenomena. Materials and Methods Magnetite Nano-Particles (MNPs) were prepared by means of co-precipitat...

Noble metal nanoparticles exhibit localized plasmon resonance modes that span the visible and near-infrared spectral ranges have many applications. Modifying size, shape, composition of changes number their properties. The characteristics these are transiently affected when illuminating nano-objects with ultrashort laser pulses. Here, we synthesize core-shell gold-silver nanocuboids measure sig...
