In an article recently published in the journal Nanotechnology, researchers employed a single particle imaging method for fluorescence excitation with moderate intensity to achieve spatial resolution. Here, the semiconductor nanocrystals were accessed, whose emission lifetimes depended on excitation intensity. Nanocrystals The excited fluorophore's de-excitation rate with optical modulation is an important tool to achieve super-resolution [...]

A new COVID-19 vaccine developed in South Australia and administered with a needle-free device is to begin human trials. Designed by University of Adelaide researchers the DNA vaccine also targets the Omicron variant of the virus and can be adapted for future variants. DNA vaccines require simple engineering design modifications that can be made [...]

Grinding is an essential manufacturing process, yet the heat due to friction associated with the process causes damage to the part being processed. Lubrication is used to reduce friction; however, traditional petroleum-based lubricants can harm the environment and are hazardous to humans. A paper published in the Journal of Cleaner Production addresses the issues associated with [...]

A team of researchers from HSE University, Skoltech, MPGU, and MISIS have developed a nanophotonic-microfluidic sensor whose potential applications include cancer detection, monitoring and treatment response assessment. Today, the device can identify gases and liquids dissolved at low concentrations with a high degree of accuracy. The paper is published in Optics Letters. According to the [...]

Researchers have made a scientific breakthrough with the development of ‘nanomachines’ that can kill cancerous cells. The research team headed by Dr Youngdo Jeong from the Center for Advanced Biomolecular Recognition at the Korea Institute of Science and Technology (KIST) has engineered molecules able to directly penetrate cancerous cells, destroying them, according to Scitechdaily. These nanomachines can kill cancer cells incredibly fast, attaching themselves to [...]

A novel freeze-dissolving approach has been devised that offers greater efficiency and sustainability compared to the classic freeze-drying process to make superfine powder or nanoparticles.​​​​​​​ In the research published in the journal ACS Sustainable Chemistry & Engineering, sphere-shaped ice particles were formed in an aqueous mixture of NH4H2PO4 or NaHCO3 to produce their respective nanoparticles. What is the Freeze-Drying Method? [...]

Would you like to help in some research on the regulation of what future AI-driven nanomedicines should look like? If so, researchers at the University of Bristol are looking for volunteers to discuss ethical and regulatory issues of using AI driven cancer therapies with swarm behaviour through a series of interviews. The research is [...]

Gold nanoparticles are minuscule particles made of gold. From drug and gene delivery to photothermal and photodynamic therapies to screening and diagnostic tests to radiation therapy, X-ray imaging and CT scans, these small particles engineered from the precious metal serve a variety of functions in the biomedical field and hold the potential for future [...]

In an article recently published in the journal Applied Surface Science, the researchers synthesized green fluorescent carbon dots (G-CDs) from 3,5-diaminobenzoic acid and citric acid. The as-prepared G-CDs were used to target the nucleolus and to carry exogenous DNA molecules into the nucleolus. In addition, the carbon dots (CDs) were used to monitor the levels [...]

Doxorubicin (DOX) is a powerful anti-cancer medication, and efforts have been made to design nanostructures for delivering it to cancerous cells. The nanostructures increase the cytotoxic effects of DOX on cancerous cells, while reducing the negative effects on healthy cells. In a research paper published in the journal Scientific Reports, layered double hydroxide (LDH) nanostructures were developed to [...]
