Challenges in Peptide Microspheres? BOC Sciences Can Solve Them!
Peptide instability and degradation
Peptide structures are sensitive and prone to inactivation due to heat, pH, or shear stress during the preparation process. BOC Sciences optimizes gentle processes and encapsulation strategies to protect peptide activity, enhancing product stability and preserving biological functionality.
Difficult control of microsphere particle size and uneven distribution
Particle size impacts release rate and injection performance, often resulting in uneven distribution due to unstable processes. We employ precision techniques such as microfluidics and membrane emulsification to precisely control the particle size range, achieving high consistency between batches.
Low drug loading efficiency and unsatisfactory release effects
Conventional processes often lead to low encapsulation rates and significant drug leakage. BOC Sciences improves the emulsion-solvent evaporation technique and material modification to enhance encapsulation efficiency and controlled release, enabling precise drug delivery.
Difficult solvent residue control affecting safety
Organic solvents are widely used in microsphere preparation, but excessive residue can impact biological safety. We optimize drying and solvent removal processes, coupled with precise detection methods like gas chromatography (GC), to ensure solvent residues are within regulatory limits.
Large batch-to-batch variability, difficult scale-up
From laboratory to pilot scale, product inconsistency often arises from imperfect process transfer. BOC Sciences follows the Quality by Design (QbD) approach, providing complete process validation and scale-up solutions to ensure stable production under GMP conditions.
Low delivery efficiency in skin or in vivo systems
Peptides are difficult to penetrate barriers and are often degraded by enzymes, impacting efficacy. We design targeted materials and functionalized encapsulating layers to enhance microsphere permeability and sustained action in skin or in vivo systems, improving therapeutic effects.
