Kumar Bishwajit Sutradhar, Md. Nanoparticles are rapidly being developed and trialed to overcome several limitations of traditional drug delivery systems and are coming up as a distinct therapeutics for cancer treatment. Conventional chemotherapeutics possess some serious side effects including damage of the immune system and other organs with rapidly proliferating cells due to nonspecific targeting, lack of solubility, and inability to enter the core of the tumors resulting in impaired treatment with reduced dose and with low survival rate. Nanotechnology has provided the opportunity to get direct access of the cancerous cells selectively with increased drug localization and cellular uptake.

Numerous investigations have shown that both tissue and cell distribution profiles of anticancer drugs can be controlled by their entrapment in submicronic colloidal systems nanoparticles. The rationale behind this approach is to increase antitumor efficacy, while reducing systemic side-effects. This review provides an update of tumor targeting with conventional or long-circulating nanoparticles. The in vivo fate of these systems, after intravascular or tumoral administration, is discussed, as well as the mechanism involved in tumor regression. Nanoparticles are also of benefit for the selective delivery of oligonucleotides to tumor cells. Moreover, certain types of nanoparticles showed some interesting capacity to reverse MDR resistance, which is a major problem in chemotherapy.

Chapter Multifunctional polymeric micelles as therapeutic nanostructures: targeting, imaging, and triggered release. Chapter Recent advances in diagnosis and therapy of skin cancers through nanotechnological approaches.
The use of nanocarriers as drug delivery systems for therapeutic or imaging agents can improve the pharmacological properties of commonly used compounds in cancer diagnosis and treatment. Advances in the surface engineering of nanoparticles to accommodate targeting ligands turned nanocarriers attractive candidates for future work involving targeted drug delivery. Furthermore, there are several formulations, which are now in various stages of clinical trials.

Although cancer survival rates have remarkably increased over the past 50 years, those in late stage cancers remain low such as glioma, pancreatic cancer, liver cancer, breast cancer, etc. Global researchers are working hard to find cures for these cancers. Among several emerged technologies over the past two Among several emerged technologies over the past two decades e. Nanoparticles possess several advantages such as combination therapy, tumor targeting, controlled release, long circulation, reduced toxicity and concurrent live imaging.
Cancer is one of the leading causes of death worldwide. In the last two decades, the development of nanotechnology has facilitated our ability to design new nanoparticles for the diagnosis and treatment of cancer. In this chapter, we reviewed the applications of gold nanoparticles as contrast agents for cancer imaging, including optical imaging, photoacoustic imaging, and X-ray—based imaging.

Еще толком не отдавая себе отчета в своих действиях и повинуясь инстинкту, она резким движением согнула ноги и со всей силы ударила Хейла коленом в промежность, ощутив, как ее коленные чашечки впились в его мягкие незащищенные ткани. Хейл взвыл от боли, и все его тело сразу же обмякло. Он скатился набок, сжавшись в клубок, а Сьюзан, высвободившись из-под него, направилась к двери, отлично понимая, что у нее не хватит сил ее открыть. Но тут ее осенило. Она остановилась у края длинного стола кленового дерева, за которым они собирались для совещаний.
Дэвид Беккер стоял в центре пустого зала и думал, что делать. Весь вечер оказался сплошной комедией ошибок. В его ушах звучали слова Стратмора: Не звони, пока не добудешь кольцо. Внезапно он почувствовал страшный упадок сил. Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно .
Мотор кашлянул и захлебнулся. - El anillo. Кольцо, - совсем близко прозвучал голос. Беккер поднял глаза и увидел наведенный на него ствол.
