Antimicrobial resistance is a global health crisis. Nanoparticles, especially metal-based ones, show promise as novel therapies against drug-resistant bacteria, including through photothermal therapy and synergistic drug combinations.

Area of Science:

  • Biomaterials Science
  • Nanotechnology
  • Microbiology

Background:

  • Antimicrobial resistance (AMR) is a significant global public health threat, driven by multidrug-resistant microbes and a lack of new effective antimicrobial drugs.
  • The WHO highlights the alarming rise in infections caused by resistant pathogens, leading to increased morbidity and mortality.
  • Novel therapeutic strategies are urgently needed to combat the growing challenge of antimicrobial resistance.

Purpose of the Study:

  • To review the current insights into antimicrobial resistance mechanisms.
  • To explore the antibacterial activity of various nanoparticles, with a focus on metals and metal oxides.
  • To discuss the application of nanomaterials in photothermal therapy and drug delivery for combating resistant infections.

Main Methods:

  • Literature review of recent findings on nanomaterials against multi-resistant pathogenic bacteria.
  • Analysis of nanoparticle antibacterial mechanisms and photothermal therapy applications.
  • Discussion of synergistic interactions, microbial adaptation, challenges, and future prospects.

Main Results:

  • Nanoparticles, particularly metal and metal oxide types, are emerging as promising therapeutic agents against drug-resistant microbes.
  • Photothermal therapy using nanomaterials offers a light-activated strategy for microbial killing and enhanced drug delivery.

Development of Antibiotic Resistance

Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Combined Effects of Drugs: Synergism01:27

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

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...
