III. THE SYSTHESIS OF HYDROGELS, THE WAYS TO LOAD DRUGS INTO<br />

HYDROGELS AND THE RELEASE OF DRUGS FROM HYDROGELS<br />

3.2. Preparation of drug-loaded hydrogels<br />

• The dry polymer blends with known<br />

weight 0.1 g), were soaked into the<br />

drug solutions at room temperature<br />

until the complete adsorption for 72 h.<br />

• Then the amount of drug adsorbed<br />

onto polymer hydrogels at different<br />

compositions w<strong>as</strong> determined by<br />

using UV–Vis spectrophotometer at<br />

identical drug absorbance wavelength.<br />

Chlorotetracycline<br />

(CTC) - Antibiotic<br />
