One of potential drug carrier for this purpose is chitosan based polyelectrolytes complexes (PECs) because micron-sized particles with good biocompatibility, non-toxic and antibacterial properties, that was inherited from chitosan, could be achieved. In this research, PECs were prepared by simple mixing method between chitosan solution and poly-2-acrylamido-2-methylprophane sulfonic acid (PAMPS) solution. The influence of chitosan concentration on obtained PECs were studied by varying chitosan concentration from 0.1 to 2.0% w/v. Based on dynamic light scattering (DLS) and zetasizer results, increasing chitosan concentration lead to increase the particle size from 1.1 m to 10.7 m and their net surface charge of particles were changed from-4,2 mV to 32.8 mV. Considering that particle size of pulmonary drug carrier should be around 1-3 m and preferable possesses positive net surface charge, PECs prepared from chitosan solution 0.5% w/v might be potentially useful as drug carrier for pulmonary drug delivery system.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antibacterial properties,Chitosan concentration,Drug concentration,Micron-sized particles,PAMPS,Pulmonary delivery,Pulmonary drug delivery,Systemic toxicities[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]chitosan,PAMPS,polyelectrolytes complexes,pulmonary drug delivery system[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research was funded by Overseas Research Collaboration Fund from Indonesian Ministry of Research, Technology and Higher Education 2018[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1757-899X/547/1/012028[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
