Nano-alternatives used in the manufacture of prosthetic limbs to reduce microbial infections

Background: This research addresses a medical and bioengineering topic: bacterial infections associated with prosthetic limb implants. This is one of the most common and serious challenges in the field of joint and limb implants, as these infections can lead to implant failure and subsequent limb loss. This review aims to reduce the use of traditional antibiotics most of which have become resistant in prosthetic limb implantation procedures to limit microbial infections. The use of non-toxic nanomaterials in various forms in the coating or manufacture of prosthetic limbs helps to minimize microbial infections that could lead to prosthetic limb implant failure. Prosthetic limb infections represent a major medical challenge because the complications they cause can negatively impact a patient's quality of life and the quality of the implant. This research revealed that bacterial infections associated with prosthetic limb implants are often resistant to conventional antibiotic treatments because of the formation of biofilms that provide a protective environment for bacteria. In contrast, nanomaterials have shown promising potential in combating these infections, both through their physical and chemical properties, which prevent bacterial adhesion, and through their ability to penetrate biofilms and kill microbes. Several types of nanoparticles (such as silver, copper and zinc) have also demonstrated high efficiency in combating microbes without affecting healthy tissue, paving the way for their widespread use in future medical applications. This research underscores the importance of combining advances in nanomaterial science with clinical practice to improve the quality of prosthetic implants and reduce infection rates.
