Nanomaterials have transformed scientific fields due to their unique physicochemical properties. This review highlights recent advances in synthesis and characterization techniques, with a focus on applications in energy, medicine-particularly cancer immunotherapy-and environmental remediation. Future challenges and directions are also addressed.
Nanomaterials, typically <100nm in size, exhibit high surface area, quantum effects, and enhanced reactivity. These properties enable their use in catalysis, drug delivery, biosensing, and energy storage [1].
Modern techniques such as green synthesis, atomic layer deposition, and electrospinning allow precise control over nanomaterial morphology. Tools like TEM, AFM, and XRD reveal structure–property relationships essential for functional optimization [2].
Energy
A. Nanostructured electrodes improve lithium-ion battery performance.
B. Quantum dots enhance solar cell efficiency via superior light absorption [3].
Medicine
Targeted drug delivery: Liposomes and polymeric nanoparticles deliver drugs directly to tumor cells, minimizing side effects.
Imaging: Gold and iron oxide nanoparticles enhance MRI and CT contrast.
Cancer Immunotherapy:
a) Nanoparticles deliver immune checkpoint inhibitors (e.g., anti-PD-1, anti-CTLA-4) to tumor sites, reducing systemic toxicity.
b) Lipid nanoparticles are used in mRNA-based cancer vaccines,
c) stimulating antigen-specific immunity [2,3].
Diagnosis:
a) Nanobiosensors detect disease biomarkers with high sensitivity.
b) Lab-on-a-chip devices enable rapid diagnostics for infectious diseases.
c) Quantum dots and SERS amplify signals in molecular assays [1].
Therapeutics:
a) Gold nanoshells enable photothermal therapy.
b) Iron oxide nanoparticles induce magnetic hyperthermia.
c) Nanocarriers improve chemotherapy delivery and RNAbased
gene modulation [3].
Environment
Nanomaterials contribute to water purification, pollutant degradation, and air filtration, offering sustainable solutions for environmental challenges [1].
Key challenges include scalability, biocompatibility, and regulatory approval. Future efforts should focus on eco-friendly synthesis, long-term safety, and integration into clinical and industrial platforms [2].
Nanomaterials are reshaping science and technology. With interdisciplinary collaboration and responsible innovation, their full potential can be realized across medicine, energy, and environmental sectors.
