Classification of drug-release textiles

Drug-encapsulated non-woven fabrics are produced by putting small fibres together in the form of sheets or web-like stractures following entangling of drug-loaded fibres or filaments mechanically, thermally, or chemically. Non-woven fabrics can be produced to meet specific requirements and are used extensively as bacterial barriers, sterile 

The electrospinning process was established in 1934 when the first patent on electrospinning was filed (Formhals, 1934). Nanofibres based on polymeric materials can be produced featuring a wide range of dimensions. The diameter of the fibre can range from 10 up to several hundred nanometres. Electrospinning can be carried out 

Phase separation is another method that can be employed for the preparation of nanoscale sttucmres and is frequently used to prepare three-dimensional tissue-engineering scaffolds. Phase separation of a polymer solution can produce a polymer-rich domain and a solvent-rich domain and this morphology can be fixed by quenching under low temperamre conditions. 

Removal of the solvent through freeze-drying or extraction can produce porous polymer scaffolds. Phase separation can be induced by changing the temperature or by adding non-solvent to the polymer solution. These are known as thermally induced and non-solvent-induced phase separation, respectively. The scaffolds obtained by
