Development and characterization of cell membrane coated Carboplatin-loaded mesoporous silica nanoparticles, functionalized with APTES, for lung cancer therapy.
Mesoporous silica nanoparticles (MSN) attracted the attention of researchers owing to their excellent properties including biocompatibility, high porosity, and optimal functionalization. These properties allow a greater drug loading capacity of different sizes for target and gene therapy. This research project uses these properties to produce a drug delivery as a target therapy in non-small cell lung cancer, using APTES-functionalized mesoporous silica nanoparticles loaded with the drug Carboplatin (CNSM-CPt) and encapsulated in the cell membrane.

Bioinspired and biomimetic nanostructured systems for nose-to-brain administration: a novel perspective for glioblastoma therapy
The blood-brain barrier (BBB) represents the main obstacle that limits adequate concentrations of different drugs designed for brain tumors therapy. The nose-to-brain delivery, which allows a direct connection to the CNS, has been proposed as an alternative. This study proposes the development of biomimetic and bioinspired nanostructured systems, containing temozolamide, the first-choice drug for glioblastoma treatment. Membrane-coated polymeric nanoparticles extracted from tumor cells will be rationally designed to provide an improved biological response, opening an unprecedented new therapeutic opportunity for GBM treatment.

Noninvasive tumor diagnostics using proteolytic activity nanosensors
The currently available diagnostic technologies of tumours are limited to relatively large lesions despite all advances in imaging techniques and the discovery of new biomarkers. A promising approach is utilizing smart nanomaterials that sense proteolytic activity misregulation in the tumour microenvironment and release a reporter in response to aid in the management of early tumour detection.

Nanosystems for siRNA delivery in glioblastoma therapy.
RNA interference using siRNA is a promising technique for the therapy of various diseases, including cancer, as it allows the specific inactivation of target genes. The effectiveness of this approach depends on nanocarriers that protect and transport this molecule to the target cells. In patients with glioblastoma multiforme, interference in genes related to cell proliferation can reduce tumor growth and improve the patient's prognosis. Therefore, this technology has the potential to transform glioblastoma treatment, providing a more targeted and less toxic approach.

Bionanomaterials as a breakthrough tool for radiotherapy
Our main focus is to improve cancer treatment, especially radiotherapy. Since such treatment is not specific for tumor cells, we studied the use of high atomic number nanoparticles as radiosensitizers. These nanoparticles increase the absorption of radiation in cancer cells, allowing treatments with lower doses of radiation, leading to a decrease in side effects for the patient.

Immunomodulatory potential, in the context of glioblastoma, of exosomes encapsulated by biocompatible polymeric nanoparticles.
Exosomes (Exo) are small vesicles that mediate intercellular communication and are produced by the endocytic system of several cell types, including cells that make up the immune system and tumor cells. Exo tumors have been used as a source of tumor antigens to sensitize the immune system and exosomes derived from dendritic cells (DC) are potentially capable of making tumor cells more immunogenic. Considering the potential of nanostructured systems for the delivery of bioactive molecules capable of stimulating the immune response, this project aims to design and use biocompatible polymeric nanoparticles (NP) loaded with exosomes derived from tumor cells (NP Exo-GBM) or cell-derived dendritic (NP Exo-DC) as immunomodulation instruments in the context of GBM.

Cell membrane-based nanocapsules containing novel chemotherapics for brain tumor therapy via nose-to-brain delivery.
Conventional glioblastoma (GBM) therapy has limited efficacy due to the blood-brain barrier presence, which limits the appropriate concentration of drugs in the brain. Due to its unique anatomical and physiological characteristics, nose-to-brain delivery has been proposed as an alternative in the drug administration destined for the CNS. This study intends to combine the antineoplastic properties of chromenes and melatonin, encapsulated in polymeric nanostructures, with the cell membrane coating technology, aiming for biological response improvement, providing valuable and innovative strategies for GBM treatment.

Carrier Nanoparticles for Controlled Release of Assets of Interest in Agriculture
Traditional fertilizers, while crucial for plant growth, can have detrimental effects on soil quality, contribute to water and air pollution, and lead to pest resistance. Innovative approaches, such as the use of microbial biological control agents (MBCAs), can act as elicitors, stimulating plant defense mechanisms. Nanotechnology offers further advancements by optimizing the delivery of defense-related compounds like Methyl Jasmonate (MeJA) and salicylic acid (SA) through zein nanoparticles coated with propylene glycol alginate (PGA), enabling controlled release. This project aims to develop these nanoparticles to enhance plant defenses and improve fruit quality, providing a sustainable alternative for agriculture.

Cisplatin-loaded nanostructured systems for the treatment of lung cancer.
Cisplatin is a drug, approved in 1978, as the gold standard for the treatment of lung cancer; however, only 10% of the drug reaches the tumor tissue. Its lack of selectivity and the predisposition of tumor cells to become drug-resistant results in high toxicity. In this scientific initiation project, the main objective is to increase the effectiveness of nanoencapsulated cisplatin aiming at specific targeting and increasing its effectiveness in antitumor treatment.
