Despite the application of aggressive surgery, radiotherapy and chemotherapy in clinics, brain tumors are still a difficult health challenge due to their fast development and poor prognosis. Brain tumor-targeted drug delivery systems, which increase drug accumulation in the tumor region and reduce toxicity in normal brain and peripheral tissue, are a promising new approach to brain tumor treatm...

In a large number of biological and environmental applications, ultrasound (US)-powered microand nanomotors have attracted considerable attention. However, their applications in biological settings have been limited due to the incompatibility of metallic motors and the lack of precision guiding. Here, we demonstrate that cellulosic polymer nanobubbles (200-800nm) can be propelled, aligned, acce...

In the present scenario, lung cancer is one of the most prevalent and malignant cancer especially among the smoking group of people. The targeted delivery of chemotherapeutic agents to the lungs represents a novel therapeutic approach in lung cancer. Lung is an ideal route for administration of anticancer drug as it provides larger alveolar surface area, low thickness of epithelial barrier & ex...

Day by day there are new developments in field of colon specific drug delivery system. Colonic drug delivery has gained increased importance not just for the delivery of the drugs for the treatment of local diseases associated with the colon like Crohn’s disease, ulcerative colitis, etc. but also for the systemic delivery of proteins, therapeutic peptides, anti-asthmatic drugs, antihypertensive...

Successful periodontal treatment is dependent on anti-inflammatory procedure which includes both mechanical and chemotherapeutic approach. Chemotherapeutic approach includes local application or sustained release of local drug delivery agents and systemic approaches. Locally delivered antimicrobial agents are administered to prevent plaque accumulation and to disinfect the root surface and adja...
