Energy trans-ducting gold nano-particles, with well-being physical, chemical and optical properties for utilization in different types of cancer therapy can be prepared through chemical seed growth reduction method. Gold nano particle is a umbrella term have a variety of size and shape. More regular gold nano-particles can be obtained by reduction of HAuCl4, selection of chemicals and parameters of growth medium are set in accordance with the required category of nano-particles. Nano-particles have longest dimension of 100 nm. Therapeutic treatments like photo-imaging, gene delivery, drug delivery, cell labeling and photo thermal therapy   can be done by gold nano particles.  They reduce the side effects of conventional therapy due to high target specificity and absorb and scatter specific wavelength of laser. Hyperthermia in cancerous cells is generated without damaging surrounding healthy tissues, cause the cell death by necrosis and apoptosis. The overall morphology of gold nano particles can be characterized by SEM and TEM.

G-quadruplexes (G4s) are a class of nucleic acids (DNA and RNA) with single-stranded G-rich sequences. Owing to the selectivity of some G4s, they are emerging as targeting agents to overtake side effects of several potential anticancer drugs, and delivery systems of small molecules to malignant cells, through their high affinity or complementarity to specific targets. Moreover, different systems are being used to improve their potential, such as gold nano-particles or liposomes. Thus, the present review provides relevant data about the different studies with G4s as drug delivery systems and the challenges that must be overcome in the future research.

Tannic acid and AuNP-TA lead to death of colon cancer cells via the ROS/p53/Akt pathway, and AuNP-TA is more potent.
