1. Introduction

Nanotechnology represents an innovative area with the potential to significantly revolutionize the treatment of cancer. When operating at the nanoscale, materials exhibit distinctive characteristics that facilitate precise handling and the directed conveyance of medications to cancerous cells. The primary objective of this manuscript is to investigate the impact of nanotechnology on the realm of cancer therapy, with a specific emphasis on its fundamental principles and utilization in contemporary oncology [1].

Conventional chemotherapy frequently encounters challenges such as inadequate drug solubility, restricted efficacy, and systemic side effects. These obstacles are effectively surmounted by nanotechnology through the encapsulation of drugs within nanocarriers, thus safeguarding them from degradation and enhancing their systemic distribution. Nanoparticles possess the capability to traverse biological barriers such as the blood-brain barrier, thereby introducing novel prospects for the treatment of previously intractable brain malignancies [2]. Tailorable nanoengineered drug conveyance systems, encompassing nanoparticles, liposomes, and dendrimers, can be designed to accumulate in tumors either through passive means (leveraging the enhanced permeability and retention effect) or actively (via the attachment of specific molecules or antibodies). This targeted strategy serves to diminish side effects while amplifying the efficacy of cancer therapies [3].

Nanotechnology’s application in cancer treatment is distinguished by its ability to amalgamate therapy and diagnosis within a singular platform, referred to as theranostics [4]. The utilization of theranostic nanoparticles facilitates both tumor imaging and precise delivery of treatments. This holistic approach allows for real-time assessment of treatment efficacy, early detection of cancer recurrence, and the tailoring of treatment strategies based on individual patient attributes [5]. Within the field of oncology, nanotechnology assumes a pivotal role in propelling precision medicine through molecular targeting methodologies. Customized therapeutic interventions guided by biomarkers specific to the molecular profile of each tumor enhance treatment outcomes while mitigating adverse effects [6]. Moreover, the integration of nanosensors and nanodevices amplifies the sensitivity of cancer biomarker identification, thereby assisting in early diagnosis and prognosis [7]. Nanotechnology represents a substantial transformation in cancer therapy, providing exact, targeted, and personalized treatment modalities. By bridging the disconnect between laboratory advancements and clinical application, nanotechnology holds the promise of ameliorating patient outcomes, diminishing treatment side effects, and ushering in a novel epoch in cancer management [8].

They have the capacity to encase diverse therapeutic substances, ranging from chemotherapeutic medications to nucleic acids, peptides, and proteins. Nanoparticles shield medications from deterioration, prolong their circulation period, and govern their release patterns. Nanoparticles can be engineered to target specific tissues or cells, enhancing the precision of drug delivery, and minimizing side effects. This targeted delivery is achieved through surface modifications that enable the nanoparticles to recognize and bind to specific biomarkers on diseased cells. Additionally, the ability to penetrate biological barriers, such as the blood-brain barrier, opens new avenues for treating central nervous system disorders [11].

2.2. Liposomes for Enclosing Hydrophobic and Hydrophilic Medications

Liposomes, lipid-based nanocarriers resembling cellular membranes, can enclose both hydrophobic and hydrophilic medications [12]. Their dual-layered structure permits the integration of lipophilic medications in the lipid bilayer and hydrophilic medications in the aqueous core. Liposomes enhance medication solubility, accessibility, and target precision, rendering them efficient carriers for chemotherapy and targeted treatments. Liposomes exhibit biocompatibility and biodegradability, reducing the risk of adverse reactions and making them suitable for clinical applications. Their ability to fuse with cellular membranes facilitates the direct delivery of encapsulated drugs into the cytoplasm, enhancing therapeutic efficacy. The surface of liposomes can be modified with polyethylene glycol (PEG) to create “stealth” liposomes, which evade detection and clearance by the immune system, thereby extending the circulation time of the drug [13]. This extended circulation allows for increased accumulation of the drug in targeted tissues, particularly in tumors, through the enhanced permeability and retention (EPR) effect.
