Classification of nanobased systems used in pharmaceuticals (1)
The nanotechnology based on pharmaceutical application can be divided into two important parts
1.Nanomaterials: The nano materials can be sub divided into nanocrystalline and nanostructured materials.
Nanocrystalline materials are readily manufactured and can substitute the less performing bulk materials. Raw nanomaterials can be used in drug encapsulation, bone replacements, prostheses
(Artificial mechanical devices to replace body parts lost in injury and or by birth e.g. artificial
limbs, facial prosthetics and neuroprosthetics etc.), and implants.
Nanostructured materials are processed forms of raw nanomaterials that provide special shapes or functionality, for example quantum dots, dendrimers, fullerenes and carbon nanotubes.
2.Nanodevices: Nanodevices can be defined divices any instruments which are much smaller in sizes generally in the nano-scale ranges .Nanodivices can be divided into electromechanical systems (NEMS/ MEMS),which include nano- and micro-electromechanical systems (NEMS/ MEMS), microfluidics(control and manipulation of micro or nanolitre of fluids), and microarrays(different kind of biological assay e.g. DNA, protein, cell, and antibody ). Examples include biosensors and detectors to detect trace quantities of bacteria, airborne pathogens, biological hazards, and disease signatures. (1)
