While these structural changes induced by laser pulses could be used to deactivate the photothermal effects of these particles after treatment, the resulting spherical particles or other particle fragments could lead to complications during or after treatment when gold nanoparticles are used for clinical treatment and imaging of cancer cells.
Nanoparticle drug delivery systems are engineered technologies that use nanoparticles for the targeted delivery and controlled release of therapeutic agents. The modern form of a drug delivery system should minimize side-effects and reduce both dosage and dosage frequency.
The depletion force is an effect of increased osmotic pressure in the surrounding solution. When colloids get sufficiently close, that is when their excluded volumes overlap, depletants are expelled from the interparticle region. This region between colloids then becomes a phase of pure solvent. When this occurs, there is a higher depletant ...
Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [1] The colloid is coloured usually either wine red (for spherical particles less than 100 nm) or blue-purple (for larger spherical particles or nanorods). [2]
Due to their unique size-dependent properties, lipid nanoparticles can possibly develop new therapeutics. The ability to incorporate drugs into nanocarriers offers a new prototype in drug delivery that could hold great promise for attaining bioavailability enhancement along with controlled and site-specific drug delivery. SLNs are also ...
Metal nanoparticles are associated with risks of neurotoxicity and cytotoxicity. These heavy metals generate reactive oxygen species, which causes oxidative stress and damages the cells' mitochondria and endoplasmic reticulum. [28] This leads to further issues in cellular toxicity, such as damage to DNA and disruption of cellular pathways.
Theranostic probes – capable of detection and treatment of cancer in a single treatment – are nanoparticles that have binding sites on their shell that allow them to attach to a desired location (typically cancerous cells) then can be imaged through dual modality imagery (an imaging strategy that uses x-rays and radionuclide imaging) and ...
Water treatment. Treatment of municipal waste water normally includes a phase where fine solid particles are removed. This separation is achieved by addition of a flocculating or coagulating agent, which induce the aggregation of the suspended solids. The aggregates are normally separated by sedimentation, leading to sewage sludge.
