Potentialities of nanomedicine and nanocarriers for infectious disease treatment

The promise of nanomedicine to revolutionize infectious disease prevention, detection, and treatment is a ray of hope. Treatment of infectious diseases, which is a critical and an unmet need, got benefited with the advent of nanoapproaches for safe and effective delivery systems. Drugs encapsulated in carrier systems made of lipids, polymers particles, or prepared as crystals at nanosize can provide long-term, targeted drug delivery. For systemic medication delivery, injectable nanocarriers are being investigated, and they are showing greater benefits over the existing conventional modalities. Preclinical and clinical research in this field has been presented here with a special emphasis on bacterial, viral, fungal, and protozoal infectious illnesses. Furthermore, the influence of nanointerventions in the form of successful cell-based vaccines as well as theranostics are facing difficulty of moving these technologies as realistic alternatives to the existing technologies available.
