Abstract

Insights

Terahertz technology shows promise in cancer diagnosis and treatment. This bibliometric analysis reviews research trends, identifying "sensor" and "design" as key areas for future oncological applications.

Area of Science:

  • Biomedical Engineering
  • Medical Physics
  • Oncology

Background:

  • Terahertz technology offers significant potential for cancer diagnosis and treatment.
  • A bibliometric analysis of terahertz technology in cancer research is currently lacking.
  • This study systematically reviews the knowledge structure and frontier trends in this field.

Purpose of the Study:

  • To systematically review the knowledge structure and frontier trends in terahertz technology for cancer research.
  • To provide a bibliometric analysis of terahertz radiation applications in oncology.
  • To identify emerging research directions in this interdisciplinary field.

Main Methods:

  • Comprehensive literature search in the Web of Science database (2001-2025).
  • Bibliometric analysis using visualization tools (VOSviewer, CiteSpace, Origin, R package bibliometrix).
  • Analysis of publication trends, productive countries, institutions, journals, authors, and research hotspots.

Main Results:

  • 774 publications analyzed, showing a consistent annual growth rate of 18.88% since 2001.
  • China, India, and the UK are top producing countries; Chinese Academy of Sciences is the leading institution.
  • Research hotspots include 'terahertz', 'design', and 'sensor', with 'metamaterial' showing recent activity.

Conclusions:

  • This bibliometric analysis serves as a reference for the development of terahertz technology in cancer diagnosis and therapy.
  • The study identifies potential research directions and offers insights for scholars in the field.
  • Terahertz technology is an evolving area with significant implications for future cancer research.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Radiation: Applications01:17

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...
