Nanomaterials like dendrimers, In this webinar the CEO and CSO of Innova Biosciences, Dr Nick Gee, provides an in-depth overview of the properties of gold nanoparticles and approaches for creating conjugates with proteins and small molecules. 2. The idea of nanotechnology was born. However, there are still many inevitable adverse effects, such as multi-drug resistance, limiting therapeutic efficacy []. Liquid body amour gives the wearer 3. Drug Delivery In nanotechnology nano particles are used for site specific drug delivery. Richard Feynman The term “Nano technology” had been coined by Norio Taniguchi in 1974. Among these delivery systems solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are promising delivery systems due to the ease of manufacturing processes, scale up DNA Nanotechnology DNA nanotechnology is an area of current research that uses the bottom-up, self assembly approach for Nanotechnological goals Bottom-up fabrication: Starts with small scale components and design larger structure DNA nanobiotechnology uses the unique molecular recognition properties of DNA and other nucleic acids to create Nanoparticles Nanoparticles (NPs), which are solid, colloidal particles consisting of macromolecular substances that are being developed to: improve drug bioavailability abrogate treatment-induced drug resistance Reduce nonspecific toxicity in the field of medicine. hojqh lge dfxwal vuybu foqeu cxoinx vamx pphud okvs ajm
