Nanotechnology : A New Option For Cancer?

Many doctors, physicians, researchers and biotech companies--including the revolutionary Seattle Genetics research facility--are now turning to antibody-assisted cancer treatments and precisely targeted cures instead of treating cancer with a cocktail of chemicals and radiation that generate risky side effects and damage the healthy tissue that patients need to recover. Cancers are among the most frightening and difficult-to-treat illnesses. Ranked as the leading cause of death and disability, cancer is actually an umbrella term that covers many different diseases. Each person faces a unique disease because cancers interact with the body's existing cells, so each case has a

Biotechnological solutions to a variety of illnesses, surgical procedures, genetic exploits and a myriad of other things are now in the form of nanotechnology. Big pharmaceutical companies now refer to many of their medications, in fact, as nanomedicines, which alludes to the nanotechnological inputs in pills that improve delivery methods and even deploy nanoparticles for specific purposes on occasion. A new study actually illustrates how attaching RNA nanoparticles that masquerade as antibodies to microvesicles capable of delivering RNA therapeutics to cancer cells.

Hugh Savagè has liver cancer. Chemotherapy failed, surgery failed. In a last ditch attempt to save his own life, Hugh signs up for a miracle trial using nanotechnology. In this trial, the widely-used chemotherapy drug Epirubicin was attached to nanodiamonds (carbon structures with a diameter of about five nanometres) to cultivate a nanodiamond-Epirubicin drug delivery complex (EPND). Researchers have found that while both the usual Epirubicin and EPND are capable of killing normal cancer cells, only EPND is capable of killing chemo resistant cancer stem cells and preventing secondary tumour formation in xenograft models of liver cancer.

Although there is not a cure for cancer, but cancer research treatment and early detection has been greatly improved by technology over the year. Improving health care and decreasing cancer related death. Technology has enabled researchers to understand cancer in ways never before, allowing more innovative treatment with less side effects and even ways to help cope with the side effects. Also, letting researchers create treatments that are more effective and personalize against the many types of cancer out there. More importantly, technology has improved cancer screening and detection at an early stage, which help increase people’s survivability. In addition, relieving people of their pain and suffering if the cancer is diagnosed at a later stage.

Cancer has become an epidemic across America. About 13 million Americans have cancer and a little over 1 million are diagnosed every year. For years Oncologist have been looking for treatments to cure this horrible disease(American Cancer Society, 2013). Chemistry has such a major impact on the research of cancer. The chemistry within Oncology & Cancer Research has greatly increased our knowledge and capabilities for developing new treatments or actually finding a significant cure (American Cancer Society,2013). This paper is explaining how chemistry is used to seek out cancer cells, treat, and also inform how the different chemicals are affecting our body.

Nanotechnology has immense numbers of avenues and directions that have been created, especially in the treatment of cancer. It is only projected to become a bigger field that’s more accurate as time passes. But is nanotechnology sustainable and though accurate, strong enough to be the best cancer therapy system? Is lung cancer too difficult to treat with nanotechnology due to its metastatic tendency? And is nanotechnology the best direction that we could be following in our quest for the treatment of cancer without damaging other tissues? As we discover more technology and tools, problems pop up as quick as we can solve past ones – toxicological aspects of cancer treatment, cost effectiveness and the like. Can these wonder child molecules created

But today, we propose for Nanomedical robots, since they will have no difficulty in identifying the target site cells even at the very early stages which cannot be done in the traditional treatment and will ultimately be able to track

Cancer is one of the leading causes of death worldwide as it can develop in almost any organ or tissue. Significant advances in understanding the cellular basis of cancer and the underlying biological mechanisms of tumour has been vastly improved in the recent years (Jiang et al. 1994). Cancer is a genetic disease which requires a series of mutation during mitosis to develop, its characteristics can be associated with their ability to grow and divide abnormal cells uncontrollable while in the mean time invade and cause nearby blood vessels to serve its need. Even though many people are affected by cancer today, the abilities which cancer cells have make it hard to find a single effective treatment for cancer. The focus of research now lies

Cancer is known to be one of the leading causes of death worldwide. Each year, this disease is responsible for taking the lives of millions of people. In recent years, our knowledge of cancer has grown immensely. We have discovered ways to lower our chances of developing cancer and even treatments for those who already have the disease. Treatments such as radiation and chemotherapy are used on patients to shrink or kills cancer cells. Sometimes these treatments work and patients enter remission and eventually become cancer free, but this doesn’t always happen. Depending on the location and type of cancer that they are

As one of the most prevalent causes of death globally, cancer has been a main focus for bioengineers. While it is understood that, to treat cancer, malignant tissue must be resected, many issues arise when these tumors are not removed thoroughly, when the tumors are not determined accurately, or when more time has passed for the cancer to spread to other parts of the body. Currently, there are various technologies and applications that are being researched such as the application of microfluidic devices (Han, Park and Kim). Many of these emerging technologies are important to continue studying and developing for numerous biomedical applications, including cancer diagnosis. While there are various technologies and applications that are currently being studied, many of these are still considered to be new and need further application, trials, and approval. In addition to

In conclusion, cancer fighting nanobots are leading into our future and leading into more new discoveries in the medical field. This new technology will not only help everyone's live but also will help the lives of cancer patients, in medical form. This invention may just be the solution to help save millions of lives in today's

While it seems like this burgeoning field has only recently blossomed, its roots date back as far as 1869, with the first reported description of CTCs by Thomas Ashworth (Ashworth, 1869). After a sparse trail of publications, early reports on methods for detecting CTCs via filtration (Salgado et al., 1959) and sedimentation (Alexander and Spriggs, 1960) emerged nearly 100 years later. Perhaps the most commonly used technique for detection today, immunomagnetic separation, was not reported until 1998 (Racila et al., 1998). In addition to introducing a new detection method, Racila et al. also demonstrated that CTCs exist early in disease and correlate with disease progression e providing a new perspective on the potential role of CTCs in modern cancer research and therapy. Today, researchers look to profiling components, including CTCs, in serial blood draws (liquid biopsy) to transform the current landscape of cancer therapy by i) determining patient prognosis, ii) monitoring tumor recurrence and therapeutic responses in real-time, iii) identifying new therapeutic targets, iv) elucidating drug resistance mechanisms, and v) improving our current understanding of tumor progression and metastatic disease. Multiple studies have demonstrated that elevated CTC counts indicate a poor prognosis for metastatic breast, prostate, colorectal, and lung cancer patients (Cristofanilli et al., 2005; Smerage et al., 2014; de Bono et al., 2008; Cohen et al., 2008; Miller et al., 2010; Krebs et al.,

In this study,the success of siRNA-based gene theraphy in vitro is doubled by in-vivo studies.However,some researchers performing siRNA delivery in vivo in mice introduce naked siRNA by high-pressure tail injections [1]. High-pressure injections, however, would be fatal for humans and are not a realistic in vivo method of naked siRNA delivery [2].I would like to know if this gold nanoparticle conjugates might be same affect on human.Because of that,I suggest that gold particles should be tracked via MRI imaging after systemic injection to evaluate targeting or manipulated to target

Inspired by the trans-endothelial migration of nanoparticle-loaded neutrophils to inflammatory sites, the application of this system in the treatment of cancer was reported 27. TA99, a monoclonal antibody, is specific for gp75 antigen on melanoma 61. When administrated, TA99 can activate and initiate neutrophil recruitment in tumor sites. In this study27, the authors addressed whether targeting of neutrophils in tumors using albumin NPs can enhance cancer immunotherapy. In a mouse model of melanoma, it was found that the internalization of albumin NPs in neutrophils and the accumulation of NPs in tumor dramatically increased after co-administration of TA99 and NPs than those with NPs alone. The further study found that the accumulation of BSA NPs in tumors was mediated by the recruitment of

Cancer disease is one the most complicated fatal disease which scientists are looking for methods to either stop or cure this malady (Hook, Ptak, Farrell, Hinkal, Panaro and Grodzinski, 2010). Based on the cancer overlook disease, the cells are transformed and infected to cancer after a while and it starts to metastasize and proliferate (ibid). The cardinal issue is that how cancer may occur based on transformation of cells and genes. To illustrate that question, there are two factors that must be carried out together preemptory; one is cell replication and gene mutation and both of which results in programmed cell death, apoptosis. (Mansoori, Mohazzabi, McCormack, and Jabbari, 2007). Veraciously, apoptosis will likely to happen when the healthy cells could not be repaired and the errors stay put on the cells (ibid). The stimuli of this kind of cells behavior still debatable (Hook et al, 2010), yet there are some explanation that how it started by a virus infection which is not going to be discuss in this paper. Nevertheless, there are multifarious techniques for cancer treatment clinically, one of the significant promising methods to struggle inhibition or prognosis of cancer is nanotechnology.
